A “Frankenstein mix” of mutations raises concerns, but the variant may remain vulnerable to current vaccines. If not, revisions will be necessary.
Omicron Variant No cases of this variant have been identified in the U.S. to date. CDC is following the details of this new variant. See CDC’s Media Statement.
Today, the U.S. Food and Drug Administration amended the emergency use authorizations (EUA) for both the Moderna and Pfizer-BioNTech COVID-19 vaccines authorizing use of a single booster dose for all individuals 18 years of age and older after completion of primary vaccination with any FDA-authorized or approved COVID-19 vaccine. The Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices will meet later today to discuss further clinical recommendations.
At a Glance A booster of the Moderna COVID-19 vaccine increased levels of neutralizing antibodies against all variants of concern in a primate study. The findings suggest that COVID-19 boosters not only lengthen immunity but help broaden and strengthen the immune response.
Today, CDC Director Rochelle P. Walensky, M.D., M.P.H., endorsed the CDC Advisory Committee on Immunization Practices’ (ACIP) recommendation that children 5 to 11 years old be vaccinated against COVID-19 with the Pfizer-BioNTech pediatric vaccine. CDC now expands vaccine recommendations to about 28 million children in the United States in this age group and allows providers to begin vaccinating them as soon as possible.
Certain antibodies and memory cells likely last more than 8 months after someone has contracted the coronavirus, especially if they have a strong immune response to COVID-19, according to a new study published Wednesday in Science.
