Booster or Third Dose - what's the difference?

  • Booster shots provide additional immunity against the virus for people whose immune systems had a response to the initial doses. To boost the immune system, the CDC recommends a Pfizer or Moderna bivalent booster 2 months after your third shot.
  • Third doses are for people whose immune systems may not have been given sufficient protection against COVID-19 from the first vaccines. Some people — due to age or a health condition that suppresses their immune system — need a third full dose for them to get to a level of immunity that’s protective. You can learn more about this from the CDC here.

*The Centers for Disease Control and Prevention (CDC) has recommended that Americans should choose to receive one of the two mRNA-based COVID-19 vaccines (Moderna and Pfizer-BioNTech) over Johnson & Johnson's single-dose shot, due to concerns about blood-clotting side effects.
