Booster Shots

Pediatric vaccine information

  • If your child is ages 6 months to 5 years and has completed their primary COVID-19 vaccine series with Moderna, and it has been at least 2 months since completion, they are eligible for the Moderna bivalent booster.
  • The Pfizer vaccine for this age group has 3 vaccines as part of the full primary series. The third shot of the series uses the bivalent vaccine. No additional booster is recommended after the third vaccine.

For more information about COVID-19 vaccinations for children, please visit the Dartmouth Health Children's Information About COVID-19 page.

The authorized COVID-19 vaccines are effective at reducing the risk of severe disease, hospitalization, and death, even against the highly contagious variants.

We encourage anyone who is eligible to get their booster shot as soon as possible.

  • Individuals aged 18 years and older who received the Janssen (Johnson & Johnson) vaccine can get their booster shot at least 2 months after their initial vaccine.
  • The CDC recommends that individuals ages 6 months and older receive a bivalent booster at least 2 months after completing the COVID-19 primary vaccination series. The only exception to this recommendation is for children ages 6 months to 4 years who have received their primary COVID-19 vaccine series with Pfizer.
  • Individuals 18 years of age and older who received the Novavax vaccine and who are moderately or severely immunocompromised are eligible to receive a bivalent booster of Pfizer-BioNTech or Moderna at least 2 months after their second dose in the primary series.
