Updated FDA Authorization, COVID-19 Vaccines

On April 18th, U.S. Food and Drug Administration amended the emergency use authorizations (EUAs) of the Moderna and Pfizer-BioNTech COVID-19 bivalent mRNA vaccines to simplify the vaccination schedule for most individuals.  See

This action includes authorizing the current bivalent vaccines (original and omicron BA.4/BA.5 strains) to be used for all doses administered to individuals 6 months of age and older, including for an additional dose or doses for certain populations. The monovalent Moderna and Pfizer-BioNTech COVID-19 vaccines are no longer authorized for use in the United States. This means you should not administer any monovalent mRNA (Pfizer or Moderna) to any age group beginning today (April 19th). 

Pfizer has provided the following resources in preparation for the upcoming change
  1. EUA Fact Sheets have been consolidated to include all age groups and there is now one EUA Fact Sheet for Healthcare Providers and one for Recipients and Caregivers.  The website is in the process of being updated, so for now, the new fact sheets are available on the FDA website at
  2. Pfizer Medical Affairs will be conducting LIVE Webinars for all healthcare providers beginning on April 19, 2023 for several weeks before transitioning to ON DEMAND content.  The full live training schedule is available at  The links for this week's sessions are provided below:
