Following suspensions by some countries of the COVID-19 Vaccine AstraZeneca over suspected blood clots, the MHRA confirms that the benefits of the vaccine in preventing COVID-19 far outweigh the risks. People should still go and get their COVID-19 vaccine when asked to do so.
Today the UK regulator, following a rigorous scientific review of all the available data, said that the available evidence does not suggest that blood clots in veins (venous thromboembolism) are caused by COVID-19 Vaccine AstraZeneca. This follows a detailed review of report cases as well as data from hospital admissions and GP records. This has been confirmed by the Government’s independent advisory group, the Commission on Human Medicines, whose expert scientists and clinicians have also reviewed the available data.
A further, detailed review into five UK reports of a very rare and specific type of blood clot in the cerebral veins (sinus vein thrombosis) occurring together with lowered platelets (thrombocytopenia) is ongoing. This has been reported in less than 1 in a million people vaccinated so far in the UK, and can also occur naturally – a causal association with the vaccine has not been established.
The MHRA’s advice remains that the benefits of the vaccines against COVID-19 continue to outweigh any risks and that the public should continue to get their vaccine when invited to do so.
