Behind the “one in seven” figure lies a bigger issue: what the UK MHRA chose not to investigate.

By Dr Clare Craig 21 April 2026
One in seven. That is the proportion of people in the MHRA’s own actively recruited surveillance cohort who reported a medically serious adverse reaction following Covid vaccination.
Over half reported at least one reaction of any kind. The data were collected between 2020 and 2022. They were not published until September 2025, and only then because Cheryl Grainger, through an FOI request and subsequent ICO appeal, forced it out.
The paper that eventually appeared, in the journal Drug Safety, was not written as a safety paper. It was written as a description of the digital platform used to collect the data — a methods paper published five months after Dame June Raine left as chief executive, nearly three years after the data were locked. The actual adverse reaction rates are reported but not analysed. The one stratification that could determine whether those rates are real was not performed.
