Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, if he will instruct the companies that undertook trials for covid-19 vaccines that have been approved by the MHRA to publish the anonymised participant level data underlying those trials.

There are no plans to do so. All trials are ongoing and it is not appropriate to publish detailed, subject level data. A sponsor may choose to publish interim results for a trial with individual listings of safety events but this will not include subject level detail. There is also an expectation that a summary of the results is published within 12 months of study completion. This applies whether the results are positive, negative, neutral or inconclusive.
