Question to the Department of Health and Social Care:

To ask Her Majesty's Government who is producing the data on how many (1) immunocompromised, or (2) immunosuppressed, people have received their fourth dose of the COVID-19 vaccine; and where it will be published.

There are two immunosuppressed groups eligible for a fourth dose of COVID-19 vaccination. The severely immunosuppressed are eligible for three primary doses and a fourth dose as a booster vaccination. The immunosuppressed aged 12 years old and over are eligible for a two primary dose course, an initial booster vaccination and an additional spring booster vaccination. There is no specific provision for a fourth dose for the wider immunocompromised population other than adults aged 75 years old and over or residents in a care home for older adults.

The UK Health Security Agency (UKHSA) publishes data for immunosuppressed people who received at least three doses. The UKHSA will publish additional data on booster doses administered in spring, which will include the immunosuppressed, although it has no current plans to report national surveillance data on fourth doses. NHS England and NHS Improvement are collecting data on the number of fourth doses administered in England. This data is currently being validated and we expect that a daily online publication will begin shortly.
