The newest suspension of AstraZeneca got here in Spain’s Castilla y León area, the place well being chief Verónica Casado mentioned Wednesday that “the precept of prudence” drove her to place a brief maintain on the vaccine that she still backed as being each efficient and mandatory.

“If there are in actual fact people of a sure age group that might have the next danger (of clotting) then we have to modify its use,” Casado informed Spanish public radio. “We’re not questioning AstraZeneca. We’d like all of the vaccines doable to achieve the purpose of 70% of the grownup inhabitants.”

French well being authorities mentioned they, too, had been awaiting EMA’s conclusions and would comply with the company’s suggestions, particularly for the five hundred,000 individuals who have obtained the primary dose of AstraZeneca.
