Booster or Third Dose - what's the difference?
- Booster shots provide additional immunity against the virus for people whose immune system had a response to the initial doses. To “boost” the immune system, Pfizer and Johnson & Johnson require another full dose, while Moderna is half the dose of the previous two shots.
- Third doses are for people whose immune systems may not have 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.
