AstraZeneca’s COVID-19 vaccine is tied to uncommon blood clots in rare cases

 

In another hiccup for AstraZeneca’s COVID-19 vaccine, data suggest it is in fact linked to blood clots that have formed in the brains of some vaccinated people, the European Medicines Agency announced April 7.
The blood clots are incredibly rare, EMA experts say. But because COVID-19 itself is deadly and can put people in the hospital, the benefits of the vaccine still outweigh the risks, they say. “We need to use the vaccines that we have to protect us from devastating effects” of COVID-19, Emer Cooke, executive director of the EMA, said in a news conference on April 7.
The EMA had previously concluded that the vaccine, developed by AstraZeneca and the University of Oxford, was not linked to blood clots overall (SN: 3/18/21).
