International vaccine guidance

Recommendations are changing rapidly for people who received the COVID-19 vaccine outside the United States.  Please view the most current recommendations on the CDC website.  

Current guidance on booster vaccination if vaccinated outside of the U.S.:

• If you received one of the two mRNA FDA-approved or FDA-authorized COVID-19 vaccines (Pfizer-BioNTech, Moderna) outside of the U.S.:
  • Complete the two-dose primary series of mRNA vaccine (Pfizer-BioNTech, Moderna).
  • Those 18 years and older are eligible for a booster vaccine six months after completing the primary series.
  • Booster can be any of the three FDA-authorized and approved vaccines (Pfizer-BioNTech, Moderna, Johnson & Johnson/Janssen).
• If you received the Johnson & Johnson/Janssen one-dose series outside of the U.S.:
  • Those 18 years and older are eligible for a booster at two months.
  • Booster can be any of the three FDA-authorized and approved vaccines (Pfizer-BioNTech, Moderna, Johnson & Johnson/Janssen).
• If you received an WHO-Emergency Use Listing approved vaccine:
  • Those 18 and older are eligible for a booster vaccine at six months.
  • Pfizer BioNTech is the recommended booster.
• If you received only one of a two-dose WHO-EUL-approved vaccine or those who received a non-WHO-approved vaccine:
  • Restart the initial vaccination with an FDA-authorized vaccine series (Pfizer-BioNTech, Moderna, Johnson & Johnson/Janssen)
  • No booster is recommended at this time.
