Thank you for your email.

MHRA has published information on the populations that have received the vaccine in the clinical trials, including any illnesses and medication they were receiving, and any adverse events experienced since receiving the vaccine. This information is available in the Public Assessment Reports (PARs) for the Pfizer/BioNTech and Oxford/AstraZeneca vaccines, which are accessible via the relevant links below. https://www.gov.uk/government/publications/regulatory-approval-of-pfizer-biontech-vaccine-for-covid-19 https://www.gov.uk/government/publications/regulatory-approval-of-covid-19-vaccine-astrazeneca

Additionally, the study results from the Pfizer/BioNTech vaccine (including the patients populations and any adverse events experienced) are available in a peer-reviewed journal, the New England Journal of Medicine. A link to this is provided below: https://www.nejm.org/doi/full/10.1056/NEJMoa2034577?query=featured_home

Based on the data received, advice has been given for use of the vaccines in individual patient groups in the Information for Healthcare Practitioners and Information for Recipients of the Vaccine. The Information for Healthcare Practitioners and Information for Recipients of the Vaccine for the Pfizer/BioNTech, Oxford/AstraZeneca and Moderna vaccines can be accessed via the below links: https://www.gov.uk/government/publications/regulatory-approval-of-pfizer-biontech-vaccine-for-covid-19 https://www.gov.uk/government/publications/regulatory-approval-of-covid-19-vaccine-astrazeneca https://www.gov.uk/government/publications/regulatory-approval-of-covid-19-vaccine-moderna

There is no specific precaution or contraindication on the use of any of the authorised vaccines in patients with multiple sclerosis (MS). The vaccine is safe to administer to patients with MS and patients on immunosuppressants. The only relevant precaution in the Information for Healthcare Practitioners states “Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to the vaccine. No data are available about concomitant use of immunosuppressants.”
