LONDON (AP) — The European Medicines Agency says people who have received a first dose of AstraZeneca’s COVID-19 vaccine should also get the second one despite the rare risk of blood clots that have been linked to the shot. In guidance issued on Friday, the European Union drug regulator said people should continue to get a second AstraZeneca dose four to 12 weeks after their first shot. The Amsterdam-based drug regulator for the 27-nation EU said earlier this month that there was a “possible link” between the AstraZeneca vaccine and rare blood clotting disorders. But it said the benefits of getting the shots outweighed the risks.
