Question to the Department of Health and Social Care:
To ask the Secretary of State for Health and Social Care, what steps his Department has taken to ensure long term monitoring of immunity in people who have received different covid-19 vaccines for each dose.
The National Institute for Health Research has commissioned the National Immunisation Schedule Evaluation Consortium to undertake the Com-CoV trial. This trial is gathering data on the long-term immune response of using different COVID-19 vaccines for the first and second dose.
Public Health England has also undertaken follow up on people given mixed schedules as part of routine care to monitor self-reported side effects and antibody response. The antibody results will be published in due course.
