The European Medicines Agency has found a possible link between the AstraZeneca COVID vaccine and rare blood clots in adults who receive the shot.
People under the age of 30 in the United Kingdom will now be offered an alternative to the AstraZeneca vaccine, due to concerns about blood clots.
A review by the drug regulator shows 79 people in the UK suffered blood clots after being given the shot, but says it’s not proof it had caused them.
COVID-19 Immunisation Professor Jim Wei Shen says it’s a precautionary measure.
“We are well aware of the high level of protection that COVID-19 vaccines provide, against that must be balanced the uncertain occurrence of extremely rare adverse events that may be associated with vaccination,” said Professor Shen.
Safety concerns have prompted more than a dozen countries in recent weeks to suspend use of the vaccine
