LONDON – The European Medicines Agency is expected to provide updated guidance Friday on how countries across Europe should use the coronavirus vaccine developed by AstraZeneca.
Earlier this month, the Amsterdam-based drug regulator for the 27-nation European Union said there was a “possible link” between the AstraZeneca vaccine and rare blood clotting disorders, but that the benefits of getting the shots outweighed the risks.
The agency's experts have since been considering related issues, including whether people who received a first AstraZeneca dose should be offered a second shot, and if there are specific risk factors that might make some people more vulnerable to developing the unusual blood clots.
