FDA Shortens Booster Interval for Moderna COVID-19 Shot to Five Months

January 10, 2022

The FDA has reduced the time required to receive a Moderna COVID-19 booster shot for people 18 years old and up from six months to five, following a primary series vaccination.

The decision came shortly after the agency updated the Emergency Use Authorization for Pfizer/BioNTech’s booster, shortening the time between completion of a primary vaccination series to five months for individuals aged 12 and older.
