The U.S. Food and Drug Administration late Thursday authorized an extra COVID-19 shot for people with compromised immune systems in a move that underscores the risk that the virus still poses to some vaccinated Americans.
The FDA’s announcement was made ahead of the CDC advisory committee’s meeting, which is scheduled for Friday. The committee is expected to decide whether the CDC should recommend an extra shot for people who are immunocompromised. Physicians say the most serious of these breakthrough cases are occurring in the immunocompromised, including organ-transplant patients, people undergoing chemotherapy, Americans taking chronic medications that can suppress their immune systems, and the elderly.“We do not believe that others—elderly or non-elderly who are not immunocompromised—need a vaccine right at this moment, but this is a dynamic process and the data will be evaluated,” Dr.
However, the regulator told MarketWatch that “the agency, along with the CDC, is evaluating potential options on this issue, and will share information in the near future.” The U.S. isn’t broadly tracking the number of breakthrough infections that are occurring, and it’s understood that vaccine-induced immunity can wane in some people, in part because the vaccines we have may be less protective against the more contagious delta variant.
