The Austrian national competent authority has suspended the use of a batch of COVID-19 Vaccine AstraZeneca (batch number ABV5300) after a person was diagnosed with multiple thrombosis (formation of blood clots within blood vessels) and died 10 days after vaccination, and another was hospitalised with pulmonary embolism (blockage in arteries in the lungs) after being vaccinated. The latter is now recovering. As of 9 March 2021, two other reports of thromboembolic event cases had been received for this batch.
