* The monovalent Novavax COVID-19 vaccine remains authorized for the following scenarios:

  • Novavax can be used as a two-dose primary series for individuals 12+ years old. The second of the two doses should be administered 3-8 weeks after the first dose. An 8-week interval between the first and second primary series doses might be optimal for some people ages 6 months–64 years, especially for males 12–39 years old.
  • Novavax can still be used as a booster dose, administered at least 6 months after a primary series, to people 18+ years old, who:
    • Have already completed a COVID-19 vaccine primary series;
    • Have not received any other booster dose(s); AND
    • Are unable or unwilling to receive an mRNA vaccine and would not otherwise receive a booster dose.
