Austria’s national medicines regulator has suspended use of a batch of the AstraZeneca vaccine after four patients were diagnosed with dangerous blood clotting conditions after receiving their jab.
One person died of multiple thrombosis – formation of blood clots within blood vessels – 10 days after their vaccine, the European Medicines Agency (EMA) said.
A second patient was diagnosed with pulmonary embolism – where blockages form in the arteries in the lungs – but is now recovering.
As of Tuesday this week, two other clotting conditions had been identified in patients that had received a dose from the same batch.
The EMA said there is currently no evidence that the vaccine caused the conditions, and that thrombosis is not listed as a potential side effect of the vaccine.
