Health officials warn that Omicron could soon become the dominant variant in the US, and preliminary data suggests that a booster dose of the Pfizer/BioNTech or Moderna vaccine provides substantially better protection against the Omicron variant than the primary two-dose series.
One year into the Covid-19 vaccination campaign in the US, here’s a breakdown of the population’s vaccination status, based on a CNN analysis of data from the US Centers for Disease Control and Prevention:
Fully vaccinated and boosted: 17% of the population, about 55.1 million peopleFully vaccinated and not boosted, despite being eligible: 27% of the population, about 91.2 million peopleFully vaccinated, but not eligible for booster: 17% of the population, about 56.2 million peoplePartially vaccinated (at least one dose): 11% of the population, about 37 million peopleNot vaccinated (those eligible – ages 5 and up): 22% of the population, about 72.8 million peopleNot eligible for vaccination (children under age 5): 6% of the population, about 19.6 million peopleFully vaccinated people 16 and older are eligible to receive a booster shot if they completed their initial two-dose series of Covid-19 vaccines from Pfizer/BioNTech or Moderna at least six months ago or their initial shot from Johnson & Johnson at least two months ago, according to CDC guidance.
The CDC notes that data on people who are fully vaccinated and those with a booster dose may be underestimated, while data on people with at least one dose may be overestimated.

(Al Drago/Bloomberg/Getty Images)US Centers for Disease Control and Prevention Director Dr. Rochelle Walensky declined to provide specific details on whether or when the CDC would change the definition of “fully vaccinated” from its current definition to include additional doses of Covid-19 vaccine, saying that data was being evaluated and recommendations would be updated “as necessary.”
“The definition right now is two doses of an mRNA vaccine or a single dose of the J&J vaccine. Certainly, as Dr. Fauci has demonstrated, and even our CDC data have also demonstrated, we are continuing to follow that science and it is literally evolving daily. And as that science evolves, we will continue to review the data and update our recommendations as necessary,” Walensky said in response to a question from CNN’s Jeremy Diamond during Wednesday’s Covid-19 Response Team briefing. But Walensky’s lack of a specific answer comes as scientists have reported significant increased protection from the Omicron coronavirus variant for those who have received a booster shot.
Covid-19 booster shots can help improve protection against the Omicron variant and there is no need for a variant-specific booster dose at this time, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said earlier in the briefing.
Fauci added that the effectiveness of the Pfizer/BioNTech coronavirus vaccine against symptomatic Omicron infection is significantly lower than against the Delta variant, but with a booster dose, it increases to 75% effective.
“The Omicron variant undoubtedly compromises the effects of a two-dose mRNA vaccine-induced antibodies and reduces overall the protection. However, as I showed on a prior slide, considerable protection still maintains against severe disease,” Fauci said while presenting data during the briefing.Walensky declined to say what more data the CDC is waiting on to make such a decision.
1 hr 49 min agoNIH study: Third dose of Moderna vaccine offers “substantial” improvement in protection against OmicronFrom CNN’s Deidre McPhillips
A third dose of Moderna’s Covid-19 vaccine offers protection against the Omicron variant that’s 20 times better than the antibody response of two doses, according to a study from the National Institutes of Health.
Dr. Anthony Fauci presented a sample of the data on Wednesday during a virtual briefing by the White House Covid-19 Response Team, noting that the full study is part of a series of data that will be published on a preprint server next week.
The neutralizing activity against Omicron was “substantially low” two weeks after just two doses of vaccine, Fauci said, but there was a “substantial degree” of improvement two weeks after a third dose. The data shows that a third dose provides protection that is “well within the range of neutralizing Omicron,” he said.
This data was part of a selection of findings from in vitro studies that Fauci presented on Wednesday.
Fauci also presented data from Pfizer/BioNTech that showed a booster dose greatly improves antibody response to the Omicron variant.
A month after a third dose, antibody levels had risen 25-fold compared to the level of protection three weeks after a second dose.
“This is one of a number of representative studies,” Fauci said.

(Robyn Beck/AFP/Getty Images)The US Centers for Disease Control and Prevention’s vaccine advisers will meet on Thursday to revisit the benefits and risks for the Johnson & Johnson Covid-19 vaccine. The Advisory Committee on Immunization Practices is scheduled to vote on the vaccine’s recommendation for use.
According to an agenda posted online on Wednesday, the group will hear presentations about thrombosis and thrombocytopenia syndrome – known as TTS – a rare but serious type of blood clot that has been linked to the vaccine, as well as the benefits and risks assessment of the vaccine.
The CDC has said for months that the J&J vaccine’s known and potential benefits outweighed the known and potential risks. However, it says, women younger than 50 years old should be aware of the rare but increased risk of TTS, which involves blood clots with low platelets. Safety monitoring has been ongoing since the adverse event was first identified in April.
The advisory committee is scheduled to meet from noon to 4 p.m. ET Thursday. It is scheduled to vote at 2:30 p.m. ET. It’s not clear what the voting question will be.
The single-dose Johnson & Johnson vaccine is authorized for use in people age 18 and older, and can be used as a booster shot for adults fully vaccinated with the J&J, Pfizer or Moderna vaccines.
The vaccine advisers will also hear a presentation on vaccine safety in children ages 5 to 11.
