Question to the Department of Health and Social Care:

To ask His Majesty's Government whether they plan to publish the data set of the UK Health Security Agency underpinning the article “Effectiveness of autumn 2023 COVID-19 vaccination and residual protection of prior doses against hospitalisation in England, estimated using a test-negative case-control study” published in May 2024.

The UK Health Security Agency (UKHSA) does not plan to publish the dataset for this article.

This work is carried out under Regulation 3 of The Health Service (Control of Patient Information; Secretary of State for Health, 2002) using patient identification information without individual patient consent. This is part of the UKHSA’s legal requirement for public health surveillance and vaccine monitoring. The full regulation is available on the GOV.UK website.

As such, authors cannot release the underlying dataset publicly for ethical and legal reasons. However, all the data used for this analysis is included as aggregated data in the manuscript tables and appendix. The full manuscript is available on the UKHSA Research Portal, on the UKHSA’s website.
