AstraZeneca back and forth

This week has seen turmoil in Europe’s pausing, or not, of the AstraZeneca Covid vaccine. With coronavirus cases rising in many places, governments faced the grimmest of dilemmas Tuesday: push on with a vaccine that is known to save lives or suspend use of AstraZeneca over reports of dangerous blood clots in a few recipients, even as the European regulator said there was “no indication” the shot was responsible.

It has created a jagged divide across the globe, forcing politicians to assess the health risks of halting the shots at a time when many countries, especially in Europe, are already struggling to overcome logistical hurdles and vaccine hesitancy among their populations.

Sweden was the latest to join a swelling group of European Union nations choosing caution over speed, even as the head of the European Medicines Agency said the agency is “firmly convinced” that the benefits of the AstraZeneca shot outweigh the risks.
