FACTBOX-Some countries limit AstraZeneca vaccine use amid concern over blood clots

Some countries are restricting use of the AstraZeneca vaccine against COVID-19 while others have resumed inoculations, as investigations into reports of rare, and sometimes severe, blood clots continue.

The European Medicines Agency and the World Health Organization have said the benefits outweigh the risks, but are monitoring the situation. AstraZeneca said in March its vaccine was 76% effective in preventing symptomatic infections in a U.S. trial, and that studies did not indicate higher risks of clotting.
