WASHINGTON — Pfizer and BioNTech said on Thursday morning that they had asked federal regulators to authorize emergency use of their coronavirus vaccine for children ages 5 to 11, a move that could help protect more than 28 million people in the United States.
More than 180 million Americans, including more than 80 percent of people over age 65, are fully vaccinated against the SARS-CoV-2 virus responsible for COVID-19. There’s no question that full vaccination is the best way to protect yourself against this devastating virus and reduce your chances of developing severe or long-lasting illness if you do get sick. But, to stay ahead of this terrible virus, important questions do remain. A big one right now is: How soon will booster shots be needed and for whom?
Today, the U.S. Food and Drug Administration amended the emergency use authorization (EUA) for the Pfizer-BioNTech COVID-19 Vaccine to allow for use of a single booster dose, to be administered at least six months after completion of the primary series in: individuals 65 years of age and older; individuals 18 through 64 years of age at high risk of severe COVID-19; and individuals 18 through 64 years of age whose frequent institutional or occupational exposure to SARS-CoV-2 puts them at high risk of serious complications of COVID-19 including severe COVID-19
The Food and Drug Administration has authorized Pfizer COVID-19 booster shots for people over the age of 65 and other at-risk Americans. The agency’s decision was the latest twist in the ongoing debate about when coronavirus booster shots would be necessary — and for whom.
In a clinical trial, researchers found that two doses of the vaccine delivered 94 percent efficacy against mild to severe Covid-19.
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.
