U.S. regulators amended the emergency authorization for Moderna Inc.’s Covid-19 vaccine to allow Americans to get a booster shot five months after receiving the initial first two shots. 

The decision by the Food and Drug Administration echoes a similar move it made earlier this week to reduce the recommended interval between the second and third doses of the Pfizer Inc.-BioNTech SE vaccine for all adults to five months. The Centers for Disease Control and Prevention also added its recommendation to the timeline.
