Protection for the primary course of the vaccine decreases over time. Staying up to date with your vaccinations keeps your immunity levels high. This will lower your chances of getting very sick from COVID-19 and ending up in hospital.
Who can get a booster
You can get a first booster if you:
are aged 16 or over
have completed your primary course of the vaccine (for most people, this is 2 doses).
If you are aged 16 or 17, you can get a Pfizer booster 6 months after your last dose.
If you are 18 or over, you can get a Pfizer booster 3 months after your last dose, or a Novavax booster 6 months after your last dose.
You can get a second booster if you are at increased risk of severe illness from COVID-19.
