Drug-maker Moderna asked the Food and Drug Administration on Thursday to authorize a fourth shot of its COVID-19 vaccine as a booster dose for all adults.
The request is broader than rival pharmaceutical company Pfizer’s request earlier this week for the regulator to approve a booster shot for all seniors.
Moderna said its request for an additional dose was based on “recently published data generated in the United States and Israel following the emergence of Omicron.”
