However, the data showed that there would be 934 extra cases of thrombocytopenia for every 10 million people after infection, compared with 107 after the first shot of the AstraZeneca jab.

The risks associated with the vaccines were also relatively short-lived, the researchers cautioned in the British Medical Journal.
