And data from the Medicines and Healthcare products Regulatory Agency (MHRA) regulator in the UK show more people have reported blood clots after having Pfizer‘s vaccine than the Oxford one — even though Pfizer‘s jab has not been suspended anywhere.

Up to February 28 there were 38 reports from approximately 11.5million doses of Pfizer‘s jab, compared to 30 from 9.7m AstraZeneca doses. However, neither figure – the equivalent of one blood clot seen in every 367,000 jabs – is thought to be higher than the risk expected in the general population.
