FDA Prioritizing Plan for Second Covid-19 Booster for All Adults
Health officials in the U.S. are working on a plan to allow a second booster of the Coronavirus vaccine for all adults. The FDA is currently working to make it a top priority. In March, second booster vaccines were authorized for adults 50 and older as well as people with weakened immune systems. Younger adults are eligible for only one booster which was authorized in November. With the dominance of BA.5, some health experts are concerned that younger adults immunity may be waning as Covid-19 cases rise and reinfections are more likely with BA.5 than with any previous variants because of immunity escape features. According to data from the CDC, BA.4 and BA.5 subvariants constitute more than 70% of new infections in the country.
