A third dose of the Pfizer-BioNTech COVID-19 vaccine may protect against omicron, the newest variant of the coronavirus labeled a "variant of concern" by the World Health Organization after it was reported by South African health officials.
The companies said Wednesday that two doses of their vaccine may provide protection from severe disease but may not be sufficient to protect against infection with omicron, according to preliminary lab data. A third dose offers more robust protection, providing a level of neutralizing antibodies against omicron similar to the level observed after two doses against the original coronavirus and other variants.
Antibody levels predict how well a vaccine may prevent infection with the coronavirus, but they are just one layer of the immune system’s defenses. The companies are also developing an omicron-specific vaccine.
Scientists and health officials are still conducting studies to learn more about omicron. There are already cases in at least one-third of U.S. states, and early information indicates it could be more contagious, but perhaps less dangerous than previous variants such as delta.
“Our preliminary, first data set indicate that a third dose could still offer a sufficient level of protection from disease of any severity caused by the omicron variant,” CEO and Co-Founder of BioNTech Ugur Sahin said in a statement.

91-year-old UK woman reflects on being first to get COVID vaccine one year later
Margaret Keenan told the BBC on Wednesday that she has had a "wonderful year" since becoming the first person to get a COVID-19 vaccine in the West's first mass immunization program. And she's still encouraging others to get vaccinated.
Keenan, 91, got her Pfizer-BioNTech shot on Dec. 8, 2020, dubbed "V-Day" or "Victory Day" by Health Secretary Matt Hancock – a phrase that typically refers to the Allied victories in World War II. Images of Keenan rolling up her sleeve made global headlines and video showed hospital staff applauding and cheering as she was wheeled down a hospital ward.
The landmark moment in the coronavirus pandemic came a year after the disease first emerged.
Keenan, a former jewelry shop employee originally from Northern Ireland, told BBC when strangers approach her in the street to thank her, she tells them to "please, please do have the jab."
"Don't think about it. Just go and have it done," she said.
Most Americans are concerned about omicron but won't nix holiday travel, poll shows
Less than two weeks after news of the omicron variant of the coronavirus spread worldwide, the vast majority of Americans have heard of it. While most are at least somewhat concerned about the variant, few say they will change their holiday plans because of it.
An Axios-Ipsos poll conducted Dec. 3 through Dec. 6 found that 94% of Americans have heard of omicron. Forty-seven percent of Americans said that while they've heard of it, they know almost nothing about it.
Nearly three-quarters of Americans, 71%, said they were at least somewhat concerned by the variant. But only 23% said they would cancel holiday travel, and 28% said they would stop gathering with people outside their households, the Axios-Ipsos survey found.
Judge blocks Biden's vaccine mandate for federal workers
A federal judge has ruled in favor of seven states and several contractors in the legal battle over enforcement of a COVID-19 vaccine mandate for federal contractors.
In a 28-page order released Tuesday, U.S. District Court Judge R. Stan Baker granted the states a preliminary injunction that halts enforcement of President Joe Biden's executive order that required all federal contractors to have their employees vaccinated.
Quoting a federal judge in Kentucky who also granted an injunction halting the enforcement of vaccine mandates last week, Baker wrote: "This case is not about whether vaccines are effective. They are." And Baker acknowledged the tragic toll of COVID in the United States and around the world.
"However, even in times of crisis, this court must preserve the rule of law and ensure that all branches of government act within the bounds of their constitutionally granted authority," Baker wrote.

Tennessee medical board deletes anti-misinformation policy amid GOP pressure
Tennessee’s medical licensing board voted Tuesday to delete a policy opposing coronavirus misinformation from its website because of fears a powerful conservative lawmaker would otherwise dissolve the board and replace its members.
The policy, unanimously adopted by the Board of Medical Examiners in September, establishes that doctors who spread demonstrably untrue information about COVID-19 vaccines could have their licenses suspended or potentially revoked. Members voted 7 to 3 to delete – but not rescind – the policy.
The deletion was spurred by Rep. John Ragan, R-Oak Ridge, a co-chair of the Joint Government Operations Committee. Over the past two months, Ragan sent letters pressuring the board to delete the policy or appear before the committee to explain itself.
Ragan later made a "threat" to dissolve the board in behind-the-scenes discussions with the Department of Health, according to a letter from a department attorney obtained by The Tennessean, part of the USA TODAY Network.
Although board members deleted the policy to appease Ragan, they said they would not abandon its original purpose.
