LONDON — The pharma giant AstraZeneca has requested that the European authorization for its COVID-19 vaccine be pulled, according to the EU medicines regulator.
AstraZeneca's COVID-19 vaccine was first given the nod by the EMA in January 2021. Within weeks, however, concerns grew about the vaccine's safety, when dozens of countries suspended the vaccine's use after unusual but rare blood clots were detected in a small number of immunized people. The EU regulator concluded AstraZeneca's shot didn't raise the overall risk of clots, but doubts remained.
