The curious case of AstraZeneca’s Covid-19 vaccine

AstraZeneca’s Covid-19 vaccine is facing a crisis of confidence, with one European country after another, as if seized by a fit of panic, temporarily suspending its use over concerns about reports of blood clots in people who received it.

Denmark, Iceland, and Norway had earlier said they would temporarily stop using the two-dose vaccine. On Sunday, Ireland announced a similar decision. France, Germany, and Italy followed on Monday.
