(Reuters) – Several countries have suspended the use of AstraZeneca’s COVID-19 vaccine after reports of blood clots in people who have received the shot even as the World Health Organization appealed to countries not to pause vaccination campaigns.
The WHO said on Monday there is no evidence that the incidents are caused by the vaccine developed with Oxford University.
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.
As of March 12, over 300 million doses of COVID-19 vaccines have been administered. No cases of death have been found to have been caused by COVID-19 vaccines to date, the WHO said in a statement on Monday.
More than 10 million people in the United Kingdom have received the vaccine with no evidence of related serious adverse events, it said.
Below is a list of countries that have taken action:
