Seven people have died from unusual blood clots after getting the Oxford-AstraZeneca vaccine in the UK, the medicines regulator has confirmed to the BBC. In total, 30 people out of 18 million vaccinated by 24 March had these clots. It is still not clear if they are just a coincidence or a genuine side effect of the vaccine. The Medicines and Healthcare Products Regulatory Agency says the benefits continue to outweigh any risk. However, concern has led to other countries including Germany, France, the Netherlands and Canada to restrict the vaccine’s use only to older people.
