Adults and children with moderately or severely impaired immunity can get a COVID-19 vaccination in the 2024 autumn round. Adults and children with severely impaired immunity may also be referred for one or more (additional) COVID-19 vaccinations, if advised by the treating physician. People with a referral for an extra COVID-19 vaccination can contact the Municipal Public Health Services (GGDs) for an appointment all year round.

Why is COVID-19 vaccination important for people with impaired immunity?

For people with severely impaired immunity, the coronavirus SARS-COV-2 could still have serious consequences. These people build up less protection after vaccination or infection. In addition, they may be receiving immunosuppressants or some other medication or treatment that lowers their protection against the virus. COVID-19 vaccination boosts immunity against the coronavirus SARS-CoV-2 and protects against severe illness and hospital admission resulting from COVID-19.

Does COVID-19 vaccination work effectively in people with impaired immunity?

Yes, COVID-19 vaccination works effectively in people with impaired immunity. However, in some people with severely impaired immunity, vaccination is sometimes less effective or does not last as long. They may need additional COVID-19 vaccinations to be sufficiently protected against serious illness caused by the coronavirus SARS-CoV-2. The treating physician can refer people for an extra COVID-19 vaccination.

Is it possible for vaccination to exhaust the immune system if someone has impaired immunity?

No, this will not exhaust your immune system. There is no reason to expect that COVID-19 vaccination will have a negative impact on your immune system, even if you receive multiple vaccinations.
