COVID booster update from the BGHC
On March 28 the U.S. Food and Drug Administration authorized the use of a second COVID-19 booster shot for persons over the age of 50. Additionally, persons over the age of 18 with compromised immune systems are also eligible for a second booster shot. Both Pfizer and Moderna mRNA shots have been granted emergency use authorization – or EUA – for a second booster. Both vaccines seem to be equally effective in boosting neutralizing antibody levels and immunity. Both vaccines can be given as second boosters at four months or more after previous booster administration.
