FDA authorises second booster dose of two COVID-19 vaccines for older and immunocompromised individuals
29 March 2022 - Today, the U.S. FDA authorised a second booster dose of either the Pfizer-BioNTech or the Moderna COVID-19 vaccines for older people and certain immunocompromised individuals.
The FDA previously authorised a single booster dose for certain immunocompromised individuals following completion of a three-dose primary vaccination series.
This action will now make a second booster dose of these vaccines available to other populations at higher risk for severe disease, hospitalisation and death. Emerging evidence suggests that a second booster dose of an mRNA COVID-19 vaccine improves protection against severe COVID-19 and is not associated with new safety concerns.
