Third doses of the COVID-19 vaccine are being offered to severely immunosuppressed people, either because of a health condition or treatment.
This is because research has found that people in this group are less likely to have received a good level of protection from their first two doses of the vaccine. A third dose is being offered to this group to try to increase their initial levels of protection.
Booster jabs are being offered to everyone over 18, and some people in other age groups, three months after the last dose of their initial course, whereas a third primary dose should be taken two months after a second Covid-19 vaccination.
We have developed a vaccine flowchart below, in partnership with Versus Arthritis and The Arthritis and Musculoskeletal Alliance (ARMA) to help people work out if they are eligible for for a third dose, booster or neither.
