In a weekly update on side effects from COVID-19 vaccines, the Medicines and Healthcare products Regulatory Agency (MHRA) said there were a total of 209 clots with low platelet counts following vaccination with AstraZeneca’s shot, compared to a total of 168 reported last week.
There were 41 deaths following the clots in Britain, the MHRA said, an increase of 9 from last week’s figures, although experts say historic cases might still be feeding through to the totals, and the clots are set to remain a rare event. About 22 million first doses of the AstraZeneca vaccine have been administered in Britain.
