Who should get additional doses of the COVID-19 vaccine?

Some individuals who received the Pfizer or Moderna vaccine may benefit from an additional dose 28 days after their second dose. This is recommended for individuals with a condition that severely weakens their immune system. Studies have shown that some people with weakened immune systems may have decreased immunity after vaccination and may be vulnerable to serious and prolonged illness from COVID-19. An additional dose can help ensure that they have enough protection against COVID-19. Additional doses are currently not recommended for anyone else at this time. Please follow up with your healthcare provider for additional information on whether you need additional doses.
