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 the jab, PA reports.
Four other countries – Estonia, Lithuania, Luxembourg, Latvia – have suspended its use to allow time for the EMA’s Pharmacovigilance Risk Assessment Committee (PRAC) to conduct an investigation.
Europe’s medicines watchdog said a preliminary probe showed that the batch of vaccines used in Austria was not likely to blame for the death of a nurse, aged 49, who received a jab.
The nurse 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, 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.
It said that the batch labelled ABV5300 comprised one million doses and had been delivered to 17 EU countries.
