Third Primary Dose Appointments

Last updated 31 October 2021

People with a severely weakened immune system at the time of their first or second dose may be eligible for a third primary COVID-19 vaccine dose. A third primary vaccine serves a different purpose than a booster vaccine.

If you had a severely weakened immune system due to an underlying health condition or medical treatment at the time of your first or second dose you may not have made a good immune response to COVID-19.

We will offer you a third primary dose of the vaccine if you are aged 12 years and over and had severe immunosuppression at the time of your first or second dose of COVID-19 vaccination.

The third dose will improve your levels of immunity to give you better protection. The Joint Committee on Vaccination and Immunisation has not yet made recommendations on whether a booster vaccination may also be needed at a later date.
