Austrian authorities have suspended batches of AstraZeneca’s COVID-19 vaccine as a precaution while they investigate the death of one person after and the illness of another after the took the shots.
“The Federal Office for Safety on Health Care (BASG) has received two reports in a temporal connection with a vaccination from the same batch of the AstraZeneca vaccine in the district clinic of Zwettl” in Lower Austria province, the health agency said in a statement.
One 49-year-old woman died as a result of severe coagulation disorders, while a 35-year-old woman developed a pulmonary embolism and is recovering, it said. A pulmonary embolism is an acute lung disease caused by a dislodged blood clot.
The health agency added that there is “no evidence of a casual relationship with the vaccination” but the remaining stocks of the affected vaccine batch are no longer being used as a “precautionary measure”.
An AstraZeneca spokesman said: “There have been no confirmed serious adverse events associated with the vaccine,” adding that all batches are subject to strict and rigorous quality controls.
Trials and real-world experience so far suggest the vaccine is safe and effective and it had been approved for use in well over 50 countries, he said.AstraZeneca also said it was in contact with Austrian authorities and would fully support the investigation.
