The third dose of the Covid-19 vaccine

Find out about the third dose of the Covid-19 vaccine, who is eligible and how to get it.

Following national guidance, people with severely weakened immune systems will be offered a third vaccine dose. This third ‘top-up’ dose will be offered to those aged over 12 who were severely immunosuppressed at the time of their first or second dose. This includes those with leukaemia, advanced HIV and recent organ transplants, as they may not have generated a full immune response to the first two doses and therefore may be less protected than the wider population.

Those with less serious immunosuppression are not included in this advice but are likely to become eligible for another dose as part of the booster programme, pending further national advice.

This third dose is part of the primary course of vaccinations for people who are severely immunosuppressed. It is not the same as a booster dose, which is given later to extend the duration of protection after the primary course of vaccinations.

How do I know if I should have a third dose?

  • If you are identified as eligible for the third dose you will be contacted and invited to attend a clinic. This could be at your own GP Practice or an alternative site.
  • Please do not contact your GP practice, you will be invited in due course.
  • The third dose should be given no sooner than 8 weeks after the second dose.
