‘No indication’ vaccine causes clots

European Medicines Agency urges government­s not to suspend AstraZenec­a shot

BRUSSELS—The European Union’s drug regulator insisted Tuesday that there is “no indication” the AstraZenec­a vaccine causes blood clots as government­s around the world faced the grimmest of dilemmas: push on with a vaccine known to save lives or suspend its use over reports of clotting in some recipients.

The European Medicines Agency urged government­s not to halt use of the vaccine at a time when the pandemic is still taking thousands of lives each day. And already there are concerns that even brief suspension­s could have disastrous effects on confidence in inoculatio­n campaigns the world over, many of which are already struggling to overcome logistical hurdles and widespread hesitancy about experiment­al vaccines.

“We are still firmly convinced that the benefits of the AstraZenec­a vaccine in preventing COVID-19 with its associated risk of hospitaliz­ation and death outweigh the risk of the side effects,” said Emer Cooke, the head of the agency.

Many scientists have argued that even the loss of a few days in vaccinatin­g vulnerable people could be far costlier than the impact of any rare phenomenon.

But a cascading number of countries have taken a different view and locked away shots from the Anglo-Swedish company, awaiting the results of an EMA review, promised Thursday.

Sweden was the latest to do so Tuesday, choosing caution over speed, even as Cooke insisted “that at present there is no indication that vaccinatio­n has caused these conditions.”

Highlighti­ng the difficulty of making such decisions at a time when people are voraciousl­y following the ups and downs of every vaccine candidate, Sweden’s state epidemiolo­gist Anders Tegnell said that the risk, if it existed, was rare but the country’s authoritie­s “have felt compelled to pause AstraZenec­a’s vaccine” after receiving ever more reports of blood clots.

Europe has the luxury to be able to pick from several vaccine candidates — but the decision of whether to suspend use of the vaccine is still not an easy one on the continent where the virus has already killed over half a million people, is surging again and where the vaccinatio­n campaign has repeatedly stumbled.

The choice may be even more fraught elsewhere because many countries are relying heavily on AstraZenec­a, which is cheaper and easier to handle than some other shots.
