You cannot usually choose which vaccine you have. During your visit to the vaccination centre, you will be assessed and offered the most appropriate vaccination dependent upon the supply available to them on the day and which one is licensed for your age group.
Most people can have any of the COVID-19 vaccines, but some people are only offered certain vaccines.
- if you’re pregnant or under 40 you’ll usually be offered the Pfizer/BioNTech or Moderna vaccines
- if you’re under 18, you’ll only be offered the Pfizer/BioNTech (Comirnaty) vaccine
You should have the same vaccine for both your first, second and third (if appropriate) primary doses, unless you had serious side effects (such as a serious allergic reaction) after your first primary dose. Most people will be offered a booster dose of the Pfizer/BioNTech vaccine or Moderna (Spikevax) vaccine.
This means your booster dose may be different from the vaccine you had for your primary vaccine doses.
