How many doses of the covid-19 vaccine do I need to get to complete my series?

The number of vaccine doses you need to complete your primary series depends on which vaccine you receive.

  • 2 doses of Pfizer-BioNTech vaccine 3–8* weeks apart for people 5 years and older.

  • 3 doses of Pfizer-BioNTech vaccine for ages 6 months through 4 years, first and second dose 3-8 weeks apart, second and third dose at least 8 weeks apart*.

  • 2 doses of Moderna vaccine 4–8* weeks apart for people ages 6 months and older.

  • 2 doses of Novavax vaccine 3-8* weeks apart for people ages 12 years and older.

  • 1 dose of Johnson & Johnson’s Janssen (J&J/Janssen) vaccine for people ages 18 and older.


Talk to your healthcare or vaccine provider about the timing for the second dose in your primary series. You should not get the second dose early. People who are moderately or severely immunocompromised may have a different immune response following COVID-19 vaccination. Please see specific COVID-19 vaccination guidance for people who are moderately or severely immunocompromised.
