A single dose of either Pfizer’s or Moderna’s updated COVID-19 vaccines will be recommended in most cases moving forward, after the Food and Drug Administration on Tuesday updated its authorizations of the shots to simplify the recommended regimens.
Adults or children older than 5 years of age who haven’t yet been vaccinated will now receive just a single dose of those “bivalent” shots, rather than a series of monovalent doses. Similarly, most individuals who previously received a monovalent vaccine can now be boosted with one bivalent dose.
