Covid-19 Vaccine: No Evidence Of Increased Risk Of Blood Clots, Says AstraZeneca’s Review

AstraZeneca's review covered more than 17 million people vaccinated in the United Kingdom and European Union.

AstraZeneca has announced that a review of safety data of people vaccinated with its Covid-19 vaccine has shown no evidence of an increased risk of blood clots.

AstraZeneca’s review covered more than 17 million people vaccinated in the United Kingdom and European Union.

“A careful review of all available safety data of more than 17 million people vaccinated in the European Union and UK with Covid-19 vaccine AstraZeneca has shown no evidence of an increased risk of pulmonary embolism, deep vein thrombosis or thrombocytopenia, in any defined age group, gender, batch or in any particular country,” the company said

Authorities in Ireland, Denmark, Norway, Iceland and the Netherlands have suspended the use of the vaccine over clotting issues, while Austria stopped using a batch of AstraZeneca shots last week while investigating a death from coagulation disorders.

“It is most regrettable that countries have stopped vaccination on such ‘precautionary’ grounds: it risks doing real harm to the goal of vaccinating enough people to slow the spread of the virus, and to end the pandemic,” Peter English, a retired British government consultant in communicable disease control,  was quoted by news agency Reuters.

As per the official announcement by the company, 15 events of deep vein thrombosis and 22 events of pulmonary embolism have been reported so far. These numbers are the same as reported by other licensed Covid-19 vaccines.

The AstraZeneca vaccine, developed in collaboration with Oxford University, has been authorised for use in the European Union and many countries but not yet by US regulators.

The company is preparing to file for US emergency use authorisation. The company said additional testing has and is being conducted by the company and the European health authorities and none of the re-tests have shown cause for concern.
