Amid the formation of blood clots in patients, Canada has suspended use of the coronavirus vaccine from AstraZeneca and Oxford, AP reported.

Vaccination with the drug will be suspended for citizens under 55 years old.

The chance of thrombosis in those vaccinated with AstraZeneca is reportedly 1 in 100,000, although it was previously thought that this side effect could be recorded in one in a million people vaccinated.

A number of European countries have suspended or banned vaccination with AstraZeneca due to the detection of thrombosis in vaccinated patients. However, the creators of the vaccine insist on its safety. The company said that a detailed study of the health status of more than 17 million people after vaccination showed no data on an increased risk of pulmonary embolism, deep vein thrombosis or thrombocytopenia.

Armenia imported 24,000 doses of this vaccine to immunize risk groups.
