Pfizer vaccine: Protection against Omicron coronavirus variant improves with three vaccine doses

Samples from people who had two doses of the Covid-19 vaccine saw, on average, a more than 25-fold reduction in neutralization ability against the Omicron variant than the earlier virus, “indicating that two doses of BNT162b2 may not be sufficient to protect against infection with the Omicron variant,” the companies said.

The companies said two doses may still provide protection against severe disease.

“Although two doses of the vaccine may still offer protection against severe disease caused by the Omicron strain, it’s clear from these preliminary data that protection is improved with a third dose of our vaccine,” Pfizer Chairman and CEO Albert Bourla said in a statement. “Ensuring as many people as possible are fully vaccinated with the first two dose series and a booster remains the best course of action to prevent the spread of COVID-19.”

The initial lab studies used serum from blood from individuals who received two or three doses of the Pfizer/BioNTech Covid-19 vaccine. The sera was collected from subjects three weeks after their second dose, or one month after a third dose. The data released Wednesday has not been peer-reviewed or published.

“We believe that with the two doses, you still have relevant protection for severe disease, but clearly the drop is antibodies is substantial,” Dr. Mikael Dolsten, chief scientific officer at Pfizer, told CNN Chief Medical Correspondent Dr. Sanjay Gupta on Wednesday. “However, the good news this morning is that our data show convincingly when you get your boost — the third boost — the antibody levels rise 25 fold and are now similar to the originally two dose boost that protected well against ancestral strains as well as Delta.

“Go and get your third boost and you have a robust, quite impressive antibody response as well as a strengthening of the other arm of the immune system, the T cells,” Dolsten said. “That’s really the takeaway … two doses is on the weak end against this new variant, T cells may help you to be protected against severe disease, hospitalization — but it’s really time to get the third boost.”

NYC anime convention may offer 'earliest looks' at Omicron spread in US, CDC director says

President Joe Biden called the preliminary results “very, very encouraging.”

“I have some good news this morning that Pfizer’s lab report came back saying that the expectation is that the existing vaccines protect against Omicron but if you get the booster you’re really in good shape. So that’s very encouraging news,” Biden told reporters on the South Lawn Wednesday.

“That’s the lab report. There’s more studies going on but that’s very, very encouraging.”

Another study, released Tuesday by researchers in South Africa, showed the Omicron coronavirus variant partly escapes the protection offered by the Pfizer vaccine. The preprint study showed people who have been previously infected and then vaccinated are likely to be well protected, and Alex Sigal of the Africa Health Research Institute in Durban, who led the study team, told CNN that boosters are also likely to protect people.

“My impression is if you get a booster you are protected, especially against severe disease,” Sigal said.

Since reports of the Omicron variant emerged in late November, US health officials have urged people to get vaccinated and boosted. Last week, the US Centers for Disease Control and Prevention began recommending all adults get a Covid-19 vaccine booster.

Adults who have had the Pfizer or Moderna Covid-19 vaccines are eligible to get a booster six months after their second shot. Those who got the Johnson & Johnson one-shot vaccine are eligible for a booster of any authorized vaccine two months after their first dose.

About a quarter of adults who are vaccinated against Covid-19 have also received a booster dose, according to CDC data. More than 144 million adults should get a booster, based on CDC guidance, but only about 48 million adults have received one.

Pfizer and BioNTech also said Wednesday they are continuing to develop a variant-specific vaccine for Omicron and it will be available by March, if it’s needed.

“I’m not sure that we’ll need it because it’s one very likely scenario that the current booster will be enough to maintain protection, but if we need one, I’m sure we can make one and the good news is that we will have it by March,” Bourla said on NBC’s “Today” show on Wednesday.

US coronavirus: The US is averaging more than 100,000 new Covid-19 cases a day, the highest level in two months

The seven-day moving average of new cases was 121,437 as of Saturday, according to data from Johns Hopkins University (JHU). Prior to this week, the US last topped the 100,000-cases-a-day mark in early October.

Also on the rise is the number of Covid-19 deaths, with a seven-day average of 1,651 people dying from the virus each day as of Saturday, the JHU data showed. Average daily deaths haven’t been this high in more than a month.

The vast majority of new cases in the US continue to be from the Delta variant, but US health officials have detected the new Omicron coronavirus variant in at least 16 states as of Saturday.

The first case was found in California on Wednesday, and by the weekend the variant had been identified in 15 other states: Colorado, Connecticut, Hawaii, Louisiana, Maryland, Massachusetts, Minnesota, Missouri, Nebraska, New Jersey, New York, Pennsylvania, Utah, Washington, and Wisconsin.

The Omicron variant has been alarming officials because early indications show it could be more contagious than the original strain, and the significant number of mutations it carries poses a potential risk of reducing some of the effectiveness the current vaccines provide. Scientists are working to determine the severity and transmissibility of Omicron — but that could take weeks, officials have said.

Still, the US is more equipped now to deal with the newly detected variant than it was during the onset of the pandemic, US Surgeon General Dr. Vivek Murthy said Thursday.

What the Omicron variant means for the holidays

“We are in such a different place now than we were one year ago because we’ve learned a lot more. We have vaccines available. We have far more tests available, and what we’ve got to do to get through this winter is to make sure that we are doubling down on our vaccination strategy,” Murthy told CNN.

The surgeon general stressed that even though there’s a lot to learn about the new variant, mitigation efforts, including masks and hand hygiene combined with physical distancing, remain effective in providing some protection.

Just under 60{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of the total US population is fully vaccinated and nearly 23{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of those have received a booster, according to the latest data from the US Centers for Disease Control and Prevention (CDC).

Delta remains the dominant strain in the world

While the Omicron variant has the potential to become the dominant strain in the US, the Delta variant continues to show up in 99.9{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of coronavirus cases, according to Dr. Rochelle Walensky, director of the CDC.

“We know what we need to do against Delta, and that is get vaccinated, get boosted if you’re eligible and continue all of those prevention measures, including masking. And those are very likely to work against the Omicron variant,” Walensky told CNN chief medical correspondent Dr. Sanjay Gupta.

Travel restrictions by country following the Omicron variant outbreak
The Delta variant managed to take over the entire nation in the early weeks of summer, changing the outlook as vaccines were rolling out and becoming more widely available. The variant continues to rage in hotspots across the country.
More than 59,000 Americans are hospitalized with Covid-19, according to data from US Department of Health and Human Services. And overall, hospitalizations have been on the rise for more than three weeks.
The World Health Organization said the Delta variant has outcompeted other variants in most countries — making it the most common strain in much of the world.

“Even if the Omicron strain doesn’t turn out to be any worse, we are losing close to a thousand people every day from the Delta variant, and that in and of itself is a reason for people to get boosted,” Dr. Richard Besser, former acting director of the CDC, told CNN earlier this week.

A medical worker seals a test tube with a Covid-19 nasal swab at the Dignity Health-GoHealth Urgent Care testing site in the international terminal at San Francisco International Airport in California, on December 2, 2021.

Stricter travel rules to begin Monday

Dr. Anthony Fauci said earlier this week that traveling during the holidays is OK — but getting vaccinated and boosted are a must.

“Just as I said and I’ll say it again, if you have a vaccinated situation, enjoy the holidays with your family in a family setting,” said Fauci, the director of the National Institute of Allergy and Infectious Diseases, at a CNN Global Town Hall.
For international travelers, proof of a negative Covid-19 test within one day of departure for the US will be required as of Monday, the Biden administration announced Thursday. Previously a test could be taken up to three days before entering the country.

Plus, any foreign national who travels to the US must be fully vaccinated, though there is no vaccination requirement for American citizens for air travel, either globally or domestically.

However, the White House said this week that a vaccine requirement for domestic travel remained on the table as an option for the future.

Today’s coronavirus news: Ontario reports another 1,053 cases, eight deaths for Saturday; Outgoing Chancellor Angela Merkel makes final appeal for Germans to get vaccinated

The latest coronavirus news from Canada and around the world Saturday. This file will be updated throughout the day. Web links to longer stories if available.

10:57 p.m.: More cases of the Omicron COVID-19 variant were confirmed in Ontario on Saturday as the province recorded more than 1,000 new virus cases for the second day running.

The latest infections involving the variant of concern emerged in Hamilton and Peel Region, according to news releases from local authorities.

Officials said a Hamilton local resident who returned from travelling to South Africa recently tested positive for Omicron, while a second potential case is under investigation with sequencing results expected in the coming days.

It also noted that Hamilton Public Health Services is conducting case and contact management and the two individuals and their case contacts continue to self-isolate.

10:18 p.m.: Five people in Sydney have contracted the omicron variant locally, New South Wales health authorities said.

The cases are linked to two schools and a climbing gym in Sydney’s western suburbs, which may also be the source of a confirmed omicron infection in the Australian Capital Territory, NSW Chief Health Officer Kerry Chant said Sunday. Urgent genome testing is under way for a number of other cases linked to the venues and should be available in coming days, she said in a video update.

New South Wales state has confirmed 15 omicron infections and more are likely, Chant said. The outbreak was seeded from infected travelers on a flight from Doha who had been in southern Africa.

Separately, Australia will begin vaccinating young children starting early next year once authorities receive final approvals in the coming weeks.

9:41 p.m.: Ten people aboard a Norwegian Cruise Line ship approaching New Orleans have tested positive for COVID-19, officials said Saturday night.

The Norwegian Breakaway had departed New Orleans on Nov. 28 and is due to return this weekend, the Louisiana Department of Health said in a news release. Over the past week, the ship made stops in Belize, Honduras and Mexico.

More than 3,200 people are on board the ship, officials said.

According to the statement, Norwegian “has been adhering to appropriate quarantine and isolation protocols as new cases and exposures have been identified aboard this vessel.”

Prior to disembarking in New Orleans, each person on board will be tested for the coronavirus. Anyone who tests positive will either go directly home or self-isolate in accommodations provided by the cruise line, officials said.

Officials did not release any information about the conditions of those who have contracted the virus.

Cruise ships were an early source of outbreaks last year at the start of the coronavirus pandemic as some ships were rejected at ports and passengers were forced into quarantine. Some passengers died of COVID-19 at sea while others fell so ill they had to be carried out of the vessels on stretchers.

The U.S. Centers for Disease Control and Prevention issued a no-sail order in March 2020, prompting a standstill that ended last June as cruise ships began to leave U.S. ports with new health and safety requirements. According to Norwegian’s website, the company requires all passengers and crew members to have been vaccinated against the virus at least two weeks prior to departure.

8:55 p.m.: About 15 people who attended an animé convention in New York in November with a Minnesota man who later was found to have the omicron variant have also tested positive for the coronavirus, the man has told health officials in his state. It is uncertain whether any of those cases involved the omicron variant.

The man said that his friends — a group of about 30 people — had come from all over the country for the event, which was held Nov. 19-21. About half of them also later tested positive for the virus, he told the officials.

The man, officials said, was fully vaccinated and had gotten a booster just weeks before the convention. He has recovered from mild symptoms that began shortly after the convention ended and has provided health officials with names and contact information of several in his group. Because the friends live in other states, their names were forwarded to those states’ health departments. Details of their cases are not known.

The Minnesota man’s case was among the first reports of omicron in the United States, and it presented a worrisome possibility for health officials: Might the animé convention, which drew tens of thousands of people to the Jacob K. Javits Convention Center for three days, have been a vector for spreading the new variant, which scientists fear may be able to spread more quickly than any other variant?

After learning that the man had attended a large convention in New York, Kathy Como-Sabetti, manager of the COVID epidemiology section for the Minnesota Department of Public Health, said, “I kind of went, ‘Wow, well, this changes our story.’ This changes the picture of what we’re dealing with.”

At the Animé NYC conference, focused around a popular animation style that originated in Japan, attendees were fairly compliant about wearing masks, the man told officials. But some rooms were very crowded, at capacity, with crowds standing shoulder to shoulder, he said.

Convention attendees were required to provide proof that they had received at least one vaccine shot, and they had to wear masks, according to the convention website. The rules allowed entry “immediately after” a first dose. People are seen as having full vaccination protection two weeks after a second dose of a two-dose vaccine.

7:37 p.m.: Australia’s Parliament House will be closed to the public for the foreseeable future after a political staffer for Greens leader Adam Bandt tested positive for the coronavirus.

The staffer is fully vaccinated and tested positive upon return to Melbourne after attending parliament last week, a spokesperson for Bandt said in a statement. Other staffers have been cleared while Bandt, who is vaccinated, is isolating until he receives a result, according to the statement.

Given the positive result, officials “have decided that Parliament House should close to the public until further notice,” the Department of Parliamentary Services said in a separate statement. Authorities said they are investigating possible close contacts, exposure locations in parliament as well as in the broader community.

The Australian Capital Territory, home to capital Canberra, recorded six cases on Sunday, a health department spokeswoman said by phone. Neighboring New South Wales state found 286 new virus cases, while Victoria state recorded 980 new infections, according to separate statements on Twitter.

6:06 p.m.: A rush of vaccine-seeking customers and staff shortages are squeezing drugstores around the U.S., leading to frazzled workers and temporary pharmacy closures.

Drugstores are normally busy this time of year with flu shots and other vaccines, but now pharmacists are doling out a growing number of COVID-19 shots and giving coronavirus tests.

The push for shots is expected to grow more intense as President Joe Biden urges vaccinated Americans to get booster shots to combat the emerging omicron variant. The White House said Thursday that more than two in three COVID-19 vaccinations are happening at local pharmacies.

And pharmacists worry another job might soon be added to their to-do list: If regulators approve antiviral pills from drugmakers Merck and Pfizer to treat COVID-19, pharmacists may be able to diagnose infections and then prescribe pills to customers.

“There’s crazy increased demand on pharmacies right now,” said Theresa Tolle, an independent pharmacist who has seen COVID-19 vaccine demand quadruple since the summer at her Sebastian, Florida, store.

5:46 p.m.: The U.K. will require all travelers to take a pre-flight COVID-19 test within 48 hours prior to their flight regardless of their vaccine status, a surprise government move that prompted a swift and angry reaction from the airline industry.

The measure, which takes effect on Dec. 7, will be temporary and be reviewed as the omicron outbreak develops, Health Secretary Sajid Javid said. More than 150 people across the U.K. have been identified with the new variant.

Travelers will be allowed to take either an instant test or a PCR test. After omicron was detected in the U.K. a week ago, the government added a required PCR test within two days of arrival, requiring travelers to self-isolate until they received a negative result.

The risk of a second lost winter has already tanked shares of airline stocks, with the Bloomberg EMEA Airline Index losing 18 per cent in November, its worst monthly performance in more than a year.

4:43 p.m.: As the number of confirmed cases of the omicron coronavirus variant rose to 160 in Britain, the government Saturday announced further tightening of travel restrictions to combat its spread. Beginning Tuesday, travelers will be required to take a coronavirus test within 48 hours of traveling to Britai…

As the number of confirmed cases of the omicron coronavirus variant rose to 160 in Britain, the government Saturday announced further tightening of travel restrictions to combat its spread.

Beginning Tuesday, travelers will be required to take a coronavirus test within 48 hours of traveling to Britain regardless of their vaccination status and restrictions will be placed on travelers from Nigeria, the country’s health secretary said in a statement. Nigeria announced Wednesday that it had detected the variant in three travelers who arrived from South Africa in November, according to Dr. Ifedayo Adetifa, director-general of the Nigeria Center for Disease Control.

The two additional measures being imposed by Britain are the latest to come after a week of heightened concern led to the introduction of a number of restrictions intended to slow the incursion of the omicron variant.

At the moment, travelers are required to self-isolate and take a coronavirus test on the second day after arriving. If that test is negative, they can end their isolation. If not, they are expected to remain in self-isolation until they do get a negative result.

4:22 p.m.: The major of Rio de Janeiro canceled plans for the city’s New Year’s Eve celebrations following advice from the state that they weren’t safe to go ahead as the first cases of the omicron variant were reported in Brazil.

“We respect science,” Mayor Eduardo Paes wrote on his Twitter account Saturday. “The City Council says it can go ahead. The State’s says no. So it can’t. We will thus cancel the official New Year’s Eve celebration in Rio.”

Paes said there was no way to organize the celebrations without a guarantee from all health authorities. The party “will be missed, but the important thing is that we continue vaccinating and saving lives,” he said.

Rio de Janeiro Gov. Claudio Castro said on his Twitter account that he’ll meet Paes next week to make a final decision on the issue.

Brazil has reported 22.1 million COVID-19 cases, with 10,627 confirmed in the last 24 hours, according to Health Ministry data. More than 20 capitals have canceled their New Year’s Eve events amid concerns regarding the omicron variant, Exame reports, citing official statements.

4:08 p.m.: One more case of the Omicron COVID-19 variant was confirmed in Ontario on Saturday as the province recorded more than 1,000 new virus cases for the second day running.

The latest infection involving the variant of concern emerged in Hamilton, according to a news release from the city. Officials said one local resident who returned from travelling to South Africa recently tested positive for Omicron, while a second potential case is under investigation with sequencing results expected in the coming days.

It also noted that Hamilton Public Health Services is conducting case and contact management and the two individuals and their case contacts continue to self-isolate.

“As we have since the beginning of the COVID-19 pandemic, Hamilton Public Health Services follows up directly with all individuals diagnosed with COVID-19 and their close contacts,” the release reads. “Hamilton Public Health Services is working with the Province of Ontario and Public Health Ontario to monitor COVID-19 variants of concern including Delta and Omicron and will take strong action if necessary.”

Canada’s first known cases of the Omicron variant emerged last week when two positive tests were confirmed in Ottawa.

3:36 p.m.: New York announced three more cases of the omicron variant of the coronavirus Saturday, bringing the number of state cases linked to the new variant to eight.

“The omicron variant is here, and as anticipated we are seeing the beginning of community spread,” state Health Commissioner Mary Bassett said in a news release.

The number of states finding the variant is growing as well, with authorities in New Jersey, Georgia, Pennsylvania and Maryland reporting their first confirmed cases Friday, and Missouri reporting its first presumed case.

The variant also has been detected in Nebraska, Minnesota, California, Hawaii, Colorado and Utah.

In New York, seven of the cases have been found in New York City, once a global epicenter of the pandemic, and the other in Suffolk County.

The arrival of omicron comes as hospitals statewide continue to strain under a surge in coronavirus cases, most traced to the delta variant, along with staffing shortages.

The number of people testing positive statewide each day for the virus has doubled in the last 30 days.

Gov. Kathy Hochul in recent days has authorized the Health Department to limit nonessential, non-urgent procedures at hospitals close to running out of beds and deployed National Guard teams to relieve healthcare workers at facilities dealing with staffing issues and surging caseloads.

Fifteen members of the National Guard arrived at Monroe Community Hospital in Rochester on Saturday, WROC reported. Lt. Gov. Brian Benjamin said Wednesday the state would send 13 National Guard teams to the western New York county, where County Executive Adam Bello has declared a state of emergency.

3:15 p.m.: Health officials in New Brunswick are reporting 77 new cases of COVID-19 on Saturday as the province prepared to enter the first phase of its so-called winter action plan.

The province will enter Level 1 of the plan as of Sunday, which is the least restrictive of the three tiers.

Among other things, masking will be required outdoors when physical distancing cannot be maintained.

Physical distancing will also be mandatory in indoor public spaces that do not require proof of vaccination, such as retail stores, malls, salons and spas.

A maximum of 20 people is permitted for informal indoor household gatherings, and 50 for informal outdoor gatherings.

And it is recommended that unvaccinated individuals who are eligible to be vaccinated should not attend household gatherings.

The province’s number of active COVID-19 cases stood at 722 as of Saturday, which included 51 people in hospital — 16 of them in intensive care.

Eighteen of the hospitalized patients were initially admitted for other reasons and contracted COVID-19 due to outbreaks at hospitals in Moncton, Saint John and Miramichi.

3:14 p.m.: Chile on Saturday reported its first case of the omicron variant of the coronavirus.

A foreign national residing in Chile returned from Ghana on Nov. 25 and tested positive in a PCR test at the Santiago airport, according to authorities.

The foreigner, who had two Pfizer vaccines, is in good health and in quarantine, while other passengers on the flight he was on were being monitored, health officials in Valparaíso said in a statement.

12:22 p.m.: A Hamilton resident who recently returned from travelling to South Africa has tested positive for the COVID-19 Omicron variant, the city of Hamilton said in a news release Saturday.

The resident is one of two people under investigation by the city’s Public Health Services.

Testing results for the second case are expected in the coming days.

The statement from the city said the two individuals and their case contacts are self-isolating.

11:47 a.m.: Quebec is reporting another jump in COVID-19 cases today with 1,512 infections and one further death attributed to the virus.

The Health Department says 225 people are hospitalized, a drop of five, including 60 people listed in intensive care, an increase of three patients.

The province hasn’t reported more than 1,500 daily infections since mid-April, and the seven-day average for new cases is 1,089.

More than half of the new cases were among people who were either unvaccinated or less than two weeks removed from receiving their first dose of vaccine.

Quebec has reported 453,380 COVID-19 cases and 11,586 deaths since the beginning of the pandemic.

Due to a technical error, the province was not able to provide an update on vaccinations today.

10:49 a.m.: Rio de Janeiro on Saturday canceled its New Year’s Eve party due to renewed COVID-19 fears.

Rio Mayor Eduardo Paes announced the decision on social media.

Paes had previously promised the biggest New Year’s Eve party ever, with multiple firework displays and artists performing on a dozen stages across the city. He said there is no decision about Carnival taking place in March.

The yearly celebration on Copacabana beach has in the past gathered more than one million locals and tourists.

Other Brazilian cities, including Sao Paulo and Salvador, have also canceled New Year’s Eve celebrations due to fears of the omicron variant,. So far, the Ministry of Health has confirmed five omnicron cases in Brazil.

9:51 a.m.: Ontario is reporting another 1,053 cases and eight deaths on Saturday.

Individuals who are not fully vaccinated represent 23.4 per cent of Ontario’s total population, amounting to 494 of Ontario’s 1,053 new reported cases, and 60 cases are in individuals with an unknown vaccination status.

The current seven-day average is 894 cases per day, which is up 22.7 per cent in a week, or a doubling pace of every 24 days.

Additionally, in the province 23,913,372 vaccine doses have been administered — 90.0 per cent of Ontarians aged 12+ have had one dose and 87.3 per cent have had two doses.

There are 284 people hospitalized with the virus, of which 220 are not fully vaccinated or have an unknown vaccination status and 64 are fully vaccinated.

In the ICU there are 160 people due to COVID-19 — 136 are not fully vaccinated or have an unknown vaccination status and 24 are fully vaccinated.

8:08 a.m.: Public Health Sudbury and Districts says it is pulling out all the stops to help curb the rapid spread of COVID-19 cases in local schools.

With more than 3,000 vaccination appointments booked in the Sudbury and Manitoulin districts for children aged five to 11 and hundreds of rapid antigen screening kits distributed to students this week, there is hope that cases will decrease ahead of the Christmas break.

Although it’s too early to tell if these “additional layers of protection” are doing the trick, a health promoter at Public Health said she is confident these measures will help protect the school community.

Joëlle Martel added the local response to these programs have been positive so far and the health unit has been on hand to answer any questions that parents/guardians might have.

“Right now, the goal is to keep kids in school,” said Martel, who works in Public Health’s school health, vaccine preventable diseases, and COVID prevention division.

“If we start seeing cases go down and the trend holds steady, then we can slowly start to remove some of those measures, but our goal remains to keep kids in school as much as possible.”

Saturday 8 a.m.: Outgoing Chancellor Angela Merkel on Saturday made what is likely her final appeal before leaving office next week for Germans to get vaccinated against COVID-19.

Merkel gave what is expected to be her last weekly video message two days after federal and state leaders decided on a series of measures meant to break a wave of coronavirus infections.

The measures include excluding unvaccinated people across the country from non-essential stores, restaurants and sports and cultural venues. In a longer-term move, Parliament will consider a general vaccine mandate.

At least 68.9{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of Germans are fully vaccinated against the coronavirus, short of the government’s aim of a minimum 75{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} vaccination rate. The number of unvaccinated residents has been blamed as a key factor in a surge of new virus cases in recent weeks.

Official figures suggest that the infection rate may now be stabilizing, but at too high a level.

Coronavirus daily news updates, December 4: What to know today about COVID-19 in the Seattle area, Washington state and the world

Editor’s note: This is a live account of COVID-19 updates from Saturday, Dec. 4, as the day unfolded. It is no longer being updated. Click here to see all the most recent news about the pandemic, and click here to find additional resources.

Health and safety measures aimed at protecting communities against the delta variant should remain as the foundation for fighting the pandemic, World Health Organization officials said Friday. The announcement came as dozens of countries continue to report cases of the mutated omicron variant.

The variant appears to be three times more likely to cause reinfection in a person than the delta and beta variants, an aspect that may shed light on how the variant quickly spread across the globe, according to a preliminary study from South African scientists, which is yet to be peer-reviewed.

Though it’s still not known how much protection current COVID-19 vaccines provide against the new variant, scientists say the vaccines still offer the most protection against severe illness and possible death.

As countries grapple with increased COVID-19 cases and uncertainties over the omicron variant, the outgoing Czech government announced it will issue a vaccine mandate for people 60 and over as well as some professional groups. Though the plan is in motion, it’s still unclear whether the succeeding health minister will enforce the mandate.

Navigating the pandemic

Omicron variant found in Washington state

Washington state health authorities Saturday confirmed three cases of the omicron variant of the coronavirus have been found in Thurston, Pierce and King counties.

The patients, two men and one woman, range in age from 20 to 39, according to the Washington State Department of Health. At least one of the three infected, a King County woman in her 20s, was vaccinated.

In a media briefing Saturday, state health officials said the emergence of the omicron variant is a cause for concern but not panic.

Little is yet known about the severity of illness it causes or about the efficacy of the vaccines against it. However, it is expected to spread much faster than other variants.

While scientists figure that out, which the officials said will take “weeks, not days,” they urged the community to adhere to the now standard COVID protection protocols: get vaccinated and get a booster shot when eligible; wear good-quality masks at indoor gatherings and at crowded outdoor venues; wash hands frequently; and stay home and away from others if you have symptoms.

U.S. colleges prepare for unknowns with omicron variant

Officials at U.S. colleges, already bracing for a potential rise in coronavirus cases when students returned to campus after Thanksgiving break, are worried about the impact of the new omicron variant, with its troubling mutations and a host of unknowns.

School leaders are wondering what will happen with the variant over the coming winter break – and how that might affect the spring semester.

For now, most schools are sticking with the virus mitigation rules and strategies they have in place, but ramping up reminders about testing, vaccination and other safety measures. And they are monitoring the situation closely, ready to pivot to more stringent rules if needed when students return after winter break.

Study: Black, Asian Britons have higher COVID-19 death rates

A report commissioned by the U.K. government concluded that almost two years into the pandemic, Black people and members of other racial and ethnic minorities in Britain are still dying with the coronavirus at higher rates than white residents.

The likely cause is thought to be lower vaccination rates among those minority populations.

Italian dentist presents fake arm for vaccine to get pass

MILAN — A dentist in Italy faces possible criminal charges after trying to receive a coronavirus vaccine in a fake arm made of silicone. 

A nurse in the northern city of Biella, Filippa Bua, said she could tell right away that something was off when a man presented the phony limb for a shot on Thursday.

“When I uncovered the arm, I felt skin that was cold and gummy, and the color was too light,’’ Bua told Italian newspaper Corriere della Sera.

New York announced three more cases of the omicron variant of the coronavirus Saturday, bringing the number of state cases linked to the new variant to eight. 

“The omicron variant is here, and as anticipated we are seeing the beginning of community spread,” state Health Commissioner Mary Bassett said in a news release.

The number of states finding the variant is growing as well, with authorities in New Jersey, Georgia, Pennsylvania and Maryland reporting their first confirmed cases Friday, and Missouri reporting its first presumed case.

A rush of vaccine-seeking customers and staff shortages are squeezing drugstores around the U.S., leading to frazzled workers and temporary pharmacy closures.

Drugstores are normally busy this time of year with flu shots and other vaccines, but now pharmacists are doling out a growing number of COVID-19 shots and giving coronavirus tests.

The push for shots is expected to grow more intense as President Joe Biden urges vaccinated Americans to get booster shots to combat the emerging omicron variant.

COVID kills a leading anti-vaccine televangelist; evangelicals don’t want to talk about it

When famed televangelist Marcus Lamb died this week at 64 after contracting COVID-19, a who’s who of conservative Christian leaders sent out regrets. Evangelist Franklin Graham said Lamb is now “experiencing heaven.” National Hispanic Christian Leadership Conference head Samuel Rodriguez called him a “faithful follower of Jesus … with a heart for the lost and broken.”

Absent was a painful truth: Lamb had led his global Christian network, Daystar, for months in spreading inaccurate information about coronavirus vaccines and instead promoting treatments that are not proven remedies. The vaccines, a May segment on Daystar said, falsely, are “killing your immune system.”

BERLIN — Outgoing Chancellor Angela Merkel on Saturday made what is likely her final appeal before leaving office next week for Germans to get vaccinated against COVID-19.

Merkel gave what is expected to be her last weekly video message two days after federal and state leaders decided on a series of measures meant to break a wave of coronavirus infections. 

The measures include excluding unvaccinated people across the country from nonessential stores, restaurants and sports and cultural venues. In a longer-term move, parliament will consider a general vaccine mandate.

The Food and Drug Administration on Friday authorized Eli Lilly’s monoclonal antibody treatment for infants and children under age 12 with COVID-19 who are at high risk of becoming severely ill from the virus because they have a condition such as obesity or diabetes.

Previously, high-risk COVID patients 12 or older had been eligible to get the drugs, which are typically administered intravenously at a clinic or hospital and have been shown to lower the risk of hospitalization and death.

OLYMPIA — More than 129,000 children ages 5 through 11 in Washington state have received their first dose of the Pfizer-BioNTech pediatric vaccine since eligibility expanded to include younger kids on Nov. 3, health officials said this week. 

“While COVID-19 is often milder in children than adults, children can still get very sick and spread the disease to family and friends, which is an even bigger concern as people gather this holiday season,” Secretary of Health Dr. Umair A. Shah said Thursday. “As a father, knowing our children are vaccinated helps me breathe a sigh of relief.”

In August, when Gov. Jay Inslee ordered state employees, health care workers and others to get vaccinated against COVID-19 by Oct. 18, officials issued a stern warning: If you quit or get fired for refusing a jab, don’t expect unemployment benefits. 

But nearly two months after the vaccination deadline, it’s unclear just how much vaccine-hesitant workers have to worry about. 

Although thousands of workers in Washington likely have quit or been fired over government and private vaccine mandates — including nearly 2,000 state employees as of Nov. 15, according to state data — just 26 mandate-related claims for jobless benefits had been flagged for review by the state Employment Security Department as of Friday. Although the review process isn’t complete, ESD officials don’t believe that any of those claims have been denied.

US Covid-19: Omicron variant is a reminder that coronavirus ‘is still in control,’ medical professor says

“But it’s fairly likely we’ll see cases,” said Dr. Francis Collins, director of the National Institutes of Health.

“It ought to redouble our efforts to use the tools that we have, which are vaccinations and boosters — and to be sure we’re getting those to the rest of the world, too,” Collins told CNN on Sunday.

“It also means we need to pay attention to those mitigation strategies that people are just really sick of, like wearing masks when you’re indoors with other people who might not be vaccinated, and keeping that social distance,” he said.

“I know, America — you’re really tired of hearing those things. But the virus is not tired of us. And it’s shapeshifting itself.”

Why Omicron ‘looks different’ from other variants

As coronavirus keeps spreading, new mutations — and new variants — are expected.

“We have seen a lot of variants pop up over the last five, six months, and most of them have not amounted to much. This looks different,” said Dr. Ashish Jha, dean of the Brown University School of Public Health.

Vaccine inequity and hesitancy made the Omicron variant more likely, scientists say
The Omicron variant has an unusually high number of mutations, with more than 30 mutations in the spike protein alone, South African genomic scientists said last week.
Spike proteins are the structures used by a virus to get into the cells it attacks.

And “10 or more” of the mutations are on the receptor binding domain, which “binds to the cells in your nasal pharynx and in your lung,” Dr. Anthony Fauci told NBC on Sunday.

“In other words, the profile of the mutations strongly suggest that it’s going to have an advantage in transmissibility,” the director of the National Institute of Allergy and Infectious Diseases said.

When experts looked at other variants, Jha said, it usually took several months for those strains to be dominant — in other words, the most common strain of the virus spreading in one area.

“This one has become dominant very quickly in South Africa in the regions where it’s been found — within a matter of days to weeks, as opposed to months,” Jha said.

“Now, the number of cases in South Africa is quite low, so it can be for other reasons as well — not just because it’s more transmissible. But the speed with which it has taken off is really unlike anything we’ve seen before.”

The new Omicron variant is a pandemic gut check

Collins said it’s not yet clear whether the Omicron variant is more contagious than the Delta variant.

“It certainly shows the signs of being able to spread quickly,” he said. “What we don’t know is whether it can compete with Delta.”

It’s also too early to tell whether the Omicron variant causes more severe illness, Collins said.

In short: “There’s still much we do not know about Omicron,” epidemiologist and infectious disease expert Dr. Celine Gounder said.

“We’re still learning,” Gounder said Sunday. “As we were saying very early in the pandemic, pandemics are not about panicking. They’re about policies, protocols and practice. And in this case, that means doing the work of characterizing the virus.”

Don’t be surprised by renewed Covid-19 restrictions, expert says

A growing number of countries have confirmed cases of the Omicron variant. Canada joined that list Sunday, when health officials confirmed two cases in Ottawa, Ontario.
The Omicron variant is spreading across Europe
Both people had recently traveled from Nigeria and are isolating, Canadian health officials said.

If the Omicron variant isn’t already in the US, it’s bound to be “soon,” said Dr. William Schaffner, a professor at Vanderbilt University Medical Center.

“It’s going to make its way around the world. It looks like that way,” Schaffner said Saturday.

And that could prompt a return to stricter Covid-19 mitigation efforts.

“I think we may, indeed, be in for a phase of many more masks, much more social distancing, and more restrictions and obligations for vaccination going forward,” Schaffner said.

News of the variant spread as Americans packed airports at almost pre-pandemic levels for Thanksgiving and at the start of the holiday season: The Transportation Security Administration said it screened about 2.3 million people at airports across the country Wednesday, making it the busiest day at security checkpoints since March 2020.

More reason to get vaccinated or boosted

About 59{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of Americans are fully vaccinated against Covid-19, and about 19{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of those fully vaccinated have received a booster dose, according to CDC data.
NIH director: New variant 'ought to redouble' vaccination and mitigation efforts

While vaccine makers test their shots against the new Omicron variant, health experts said it’s important for anyone eligible to get a Covid-19 vaccine or booster to do so now.

“The main things people can do to protect themselves right now is if you’re not vaccinated, get vaccinated,” Gounder said. “If this does turn out to be an immune-evading variant, there may also well be benefit in getting an extra dose or booster dose of vaccine.”

Fauci offered similar advice: “If ever there was a reason for the people who were vaccinated to get boosted, and for those who were unvaccinated to get vaccinated, it’s now,” he told NBC.

“If you’re six months or more from the second dose of an mRNA (vaccine) — either the Pfizer or the Moderna — get boosted. If you’re two months or more following the single dose of J&J, get boosted.”

Fauci said he believes the current vaccines — and especially booster doses — will help at least somewhat against the Omicron variant.

“When you get boosted, the level of your antibody goes way, way above what the level at its peak was after the second dose,” Fauci told NBC.

“And that’s the reason why we feel even with variants like Omicron that if you get boosted, you’re going to get a level of antibody that’s high enough that it is likely you’ll be able to get at least some degree — and maybe a lot — of protection against this.”

Moderna said it’s testing the ability of its Covid-19 vaccine to neutralize Omicron, and data is expected in the coming weeks.

The company said it’s also testing a larger-dose booster and an Omicron-specific booster in case the current vaccine and booster don’t sufficiently work against the new variant.

If scientists determine an Omicron-specific vaccine dose is needed, “we think within weeks to maybe two to three months, we would be able to have a Omicron-specific vaccine booster available for testing,” Moderna Chief Medical Officer Dr. Paul Burton said Sunday.

BioNTech, the German company that partnered with Pfizer to make a Covid-19 vaccine, is also investigating Omicron’s impact on their vaccine, with data expected in the coming weeks.

Johnson & Johnson said it’s also testing the effectiveness of its vaccine against Omicron.

Moderna said the Omicron variant could be a challenge.

“The combination of mutations represents a significant potential risk to accelerate the waning of natural and vaccine-induced immunity,” the company said Friday.

But Jha said he doesn’t think the new variant means “vaccines will be rendered useless.”

“I think that’s exceedingly unlikely,” he said. “The question is, is there a tiny hit to vaccine efficacy, or is there a large hit?”

‘A couple of weeks of uncertainty’

The world is in a 'race against time' with the Omicron variant, European Commission president says

Before scientists can say how much the current vaccines might work against Omicron, “we have to go through a couple of weeks yet of uncertainty,” Burton said.

“There are three questions we really need answers to: How transmissible is this variant? How severe is it? And will the antibodies produced in response to the current vaccines (be) effective? And we won’t know that (answer to the) last question for a couple of weeks,” Burton told CNN on Sunday.

“But what we do know is that the best protection is to get vaccinated. If you’re on the fence, if you haven’t been vaccinated, get vaccinated. And now everybody over 18 in this country is at least eligible for boosting. So if you’re now eligible for boosting, get boosted as well,” he said.

“By doing that, we at least know that you’ll get that first line of critical protection. And then of course, there are additional, simpler things you can do — hand washing, some social distancing, mask wearing as appropriate. These two together, right now — until we know exactly what’s going on — are going to be critical in our line of defense.”

‘The virus is still in control … tighten your seat belts’

With or without the Omicron strain, the US is still struggling with the Delta variant.

Covid-19 hospitalizations in 16 states increased by more than 50{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} in the past week compared to the previous week, according to the US Health and Human Services Department.

“I think we need to just get our mind set that the virus is still in control. I don’t care about your Covid fatigue,” Schaffner said.

“We’re going to have to deal with this in an ongoing way very, very seriously. … Tighten your seat belts.”

F.D.A. Authorizes Coronavirus Booster Shots for All Adults

WASHINGTON — The Food and Drug Administration on Friday authorized booster shots of the two the Pfizer-BioNTech and Moderna vaccines for absolutely everyone 18 and more mature, opening up eligibility to tens of hundreds of thousands extra fully vaccinated grownups.

The transfer simplifies eligibility, fulfills a pledge by President Biden to supply the pictures to just about every American grownup and formally lets a observe already in put in at minimum 10 states. Fearful that waning defense and the onset of wintertime will established off a wave of breakthrough bacterial infections, a rising quantity of governors experienced currently provided boosters to every person 18 and more mature forward of the holiday seasons.

The company claimed the expansion was justified by presently out there scientific trial details as well as genuine-environment proof. In a statement, Dr. Peter Marks, who sales opportunities the F.D.A. division that regulates vaccines, extra: “Streamlining the eligibility requirements and creating booster doses offered to all people 18 several years of age and older will also aid to get rid of confusion about who could receive a booster dose and be certain booster doses are readily available to all who might require just one.”

Dr. Anthony S. Fauci, the federal government’s prime infectious disorder expert, has argued relentlessly more than the past month for booster shots for all older people, a place shared by most of Mr. Biden’s other health advisers. General public well being authorities who argue that healthy youthful older people do not need to have them, he has said, are ignoring the hazards of symptomatic Covid-19.

“Enough is plenty of. Let’s get shifting on below,” he stated at an occasion Wednesday night time. “We know what the info are.”

If the Centers for Disease Manage and Avoidance agrees, all grownups who gained a 2nd shot of either Pfizer or Moderna at the very least 6 months back will most probably be able to get a booster shot by the weekend. The agency’s outside advisers are conference to talk about the situation at midday Friday and will hear from Pfizer, Moderna and C.D.C. workers. A vote is scheduled for 2:45 p.m.

At a White Residence briefing on Wednesday, Dr. Rochelle Walensky, the C.D.C. director, promised that the agency would “quickly review the safety and usefulness knowledge and make suggestions as shortly as we hear from F.D.A.”

The F.D.A.’s motion came soon after months of fierce debate within the administration and the scientific community about who wanted booster photographs, and when. As huge experiments showed defense from all three federally approved vaccines keeping strongly, some outside the house advisers to the F.D.A. and C.D.C. consistently expressed distress with how promptly the administration was relocating to supply the shots.

When the F.D.A. has been evaluating booster details for months, it granted the companies’ requests with exceptional speed. Pfizer-BioNTech filed its request around 10 days back, and Moderna introduced Wednesday that it experienced applied but did not say when.

The agency said that it did not convene its impartial vaccine advisory committee for the reason that the panel experienced already experienced discussed the use of booster pictures thoroughly and “the requests do not increase concerns that would profit from further discussion.” The panel’s tips are nonbinding.

For Moderna, regulators stated, the facts confirmed that 149 scientific trial contributors who received a booster dose experienced higher antibody degrees in comparison with 1,055 review volunteers who acquired only two doses. They claimed Pfizer’s info for 200 members in a clinical trial showed the booster shot raised antibody stages compared to 1 thirty day period soon after a next shot.

Critics have mentioned the administration’s booster marketing campaign was determined by functional or political causes more than scientific kinds. Some explained that federal regulators had been examining safety and efficacy information on the fly. Others have fearful that moving to obvious Pfizer and Moderna booster doses for all older people may possibly inadvertently undermine the vaccines and counsel that two doses are not strongly protecting.

“The proof isn’t there that a large rollout of boosters is definitely going to have that considerably impact on the epidemic,” said Ira M. Longini Jr., a vaccine professional and professor of biostatistics at the College of Florida. He explained that booster doses could boost security at least briefly and may aid a jittery community sense as if they have a further tool in the pandemic, but would do tiny to halt transmission of the virus, which is becoming pushed by the unvaccinated.

Other general public overall health specialists have argued that data from Israel, which rolled out an aggressive booster campaign over the summer time, suggests boosters can reduce transmission premiums they say the added shots are necessary equally to counteract waning security and to limit confusion.

Elaborate eligibility rules coupled with the government’s recent determination to permit men and women pick among the all three vaccines for their booster have also still left the general public somewhat befuddled, proponents of the F.D.A.’s decision on Friday say.

“This conclusion by F.D.A. is overdue,” said Dr. Elizabeth McNally, director of the Centre for Genetic Drugs at Northwestern University’s Feinberg College of Drugs.

“Many individuals experienced difficulties comprehending regardless of whether they ought to or should not get boosters,” she explained in a statement. “This information is considerably clearer — get a booster!”

There is close to universal arrangement among federal officials, point out overall health leaders and exterior experts that persuading the tens of hundreds of thousands of Us citizens who have but to get even their initially shot should stay the prime precedence in making an attempt to curb the pandemic.

Extra than 182 million grown ups in the United States, or 71 percent, are totally vaccinated. So significantly, extra than 32 million of them have gotten an further shot.

Until eventually now, all those qualified for boosters involved folks 65 and older, people of extensive-term treatment facilities, folks with fundamental health care conditions, and individuals whose work or institutional living conditions heightened their risk.

All recipients of Johnson & Johnson’s a single-shot vaccine have presently been cleared to get a booster shot at least two months just after their injection.

Jason L. Schwartz, an affiliate professor of health coverage at the Yale University of Public Wellbeing, explained the most up-to-date shift was “a recognition that the present-day approach to booster tips just is not performing.”

“It’s so confusing that I feel the public has type of shrugged at the importance of boosters,” he explained. “And the teams for whom it’s really important to get boosters — the older people today, the lengthy-time period care people, folks with health-related conditions — aren’t finding boosters at the rates they must. It’s time for a reset.”

The booster rollout is increasing even as community wellbeing industry experts carry on to argue about no matter if young, balanced grownups need added defense. The argument is more robust for recipients of Pfizer’s vaccine than for recipients of Moderna’s, whose security has proved much more strong.

When some reports have observed that the Pfizer vaccine’s effectiveness in opposition to infection and hospitalization drops about 4 months following the 2nd dose, Moderna’s usefulness has remained steadier.

At the similar time, regulators have been anxious by information from Nordic nations and elsewhere suggesting that youthful male Moderna recipients may possibly confront heightened pitfalls of myocarditis, or inflammation of the heart muscle mass — a facet impact that has also been tied to the Pfizer vaccine. The F.D.A. on Friday current the vaccine’s simple fact sheets to take note that some experiments have advised there may possibly be an amplified hazard in adult males beneath 40 “relative to other authorized or authorized mRNA Covid-19 vaccines.”

Regulators stated that while facts was constrained, evidenced proposed a reduced hazard of myocarditis following booster doses than right after 2nd doses of the shot. Concerns about myocarditis are behind the F.D.A.’s selection to wait around to authorize the Moderna vaccine for adolescents.

Scientists have explained the absolute possibility nevertheless continues to be incredibly small, most scenarios are gentle and solve immediately and that Covid-19 can also bring about myocarditis.

The F.D.A. mentioned on Friday that in reviewing broader booster eligibility for Moderna’s and Pfizer’s vaccines, it had examined the latest virus instances and actual-earth knowledge on the dangers of myocarditis and concluded that the added benefits of a booster shot outweighed the challenges. The F.D.A. also noted that the two organizations had been conducting more scientific studies on myocarditis possibility.

At the coronary heart of the booster debate is the query of what vaccines are meant to do. Critics of the administration’s policy argue that despite some diploma of waning safety, the vaccines are even now fulfilling their mission of guarding versus severe illness and hospitalization.

Booster advocates like Dr. Fauci counter that the vaccines ought to also protect against symptomatic condition, in particular considering that some clients prevent hospitalization but endure extensive-time period repercussions.

“I really do not know of any other vaccine that we only stress about trying to keep persons out of the hospitals,” Dr. Fauci claimed at a White House briefing Wednesday. “I believe an significant issue is to avoid people today from finding symptomatic illness,” which includes younger men and women.

In current weeks, point out following point out has moved to allow for booster shots for all older people, which include Massachusetts, Rhode Island, Kansas, Kentucky, Maine, Vermont, Arkansas, California, Colorado and New Mexico.

A host of other nations around the world have taken the exact same technique, which includes Australia, Brazil, Canada, Germany, Hungary, Israel, Japan, Norway and Saudi Arabia. Regulators for the European Union have authorized booster doses of equally Moderna and Pfizer-BioNTech for all adults.
