At least 17 countries have suspended or delayed using AstraZeneca COVID-19 vaccines after reports of blood clots in people who have received the shot even as the World Health Organization appealed to governments not to pause vaccination campaigns.
The European medicines regulator, which is reviewing the matter, will announce its findings on Thursday after discussing information gathered into whether the vaccine contributed to blood clotting events in those inoculated. It said it continues to believe the benefits of the vaccine outweigh the risks.
The number of thromboembolic events in vaccinated people is no higher than the number seen in the general population, the European Medicines Agency has said.
As of March 10, 30 cases of thromboembolic events had been reported among close to 5 million people vaccinated with AstraZeneca’s shot in the European Economic Area.
More than 300 million doses of COVID-19 vaccines had been administered as of March 12 and no cases of death had been found to have been caused as a result, the World Health Organization said on Monday.
