Information for people with a weakened immune system

Adults with a weakened immune system

If you have a weakened immune system due to a health condition or medical treatment, and you are aged 6 months or over, you are eligible for a COVID-19 vaccination this autumn if it has been at least 3 months since your last vaccination.

This is to help improve any protection you may have built from previous vaccination or infection.

By having a further dose of vaccine, you may reduce your chance of catching the COVID-19 infection. If you do catch COVID-19, the symptoms may be less severe and the illness shorter than if you had not had the extra vaccination.

Further information, including about those who may need an extra dose this autumn, is available. You should receive a letter inviting you to book. If not, check with your GP or specialist whether you are eligible.

The autumn campaign began on 11 September 2023 in England, with those with a weakened immune system being able to book from this date. Vaccination of residents in care homes will also start from 11 September 2023.

Those eligible for a vaccine can also book on the national system from 18 September 2023. It might help to take the vaccination invite letter, or an NHS letter describing your condition or treatment, or a repeat prescription slip with you.
