Question to the Department of Health and Social Care:

To ask Her Majesty's Government what plans they have, if any, to test people with immunodeficiencies for their individual responses to COVID-19 vaccinations.

The UK Health Security Agency is working with a range of partners, such as the University College of London, to monitor the effectiveness of COVID-19 vaccinations in clinical risk groups, including those with immunosuppression. The VirusWatch study is underway to monitor antibody response following vaccination among individuals with immunosuppression.

As part of the COVID-19 Immunity National Core Study, the UK Research and Innovation OCTAVE study is examining the effectiveness of vaccines in clinically at-risk groups. This includes vaccine responses in patients with certain immunosuppressed conditions.
