AstraZeneca doesn't cause blood clots: UK

The UK's medicines regulator says the evidence does not suggest that the AstraZeneca vaccine causes blood clots but adds that a very rare and specific type of blood clot in cerebral veins is being investigated.

"The available evidence does not suggest that blood clots in veins (venous thromboembolism) are caused by COVID-19 vaccine AstraZeneca," the MHRA said.

"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."
