LONDON (AP) — The European Union’s drug regulatory agency says experts have concluded that the AstraZeneca vaccine is not linked to an overall increase in the risk of blood clots and that the benefits of use outweigh the risks. The finding from the European Medicines Agency could open the way for European countries that had suspended the use of the vaccine over the past week to resume dispensing the shots. The head of the EMA, Emer Cooke says the vaccine is “safe and effective.”
