Covid-19: EU drug agency says there is no link between AstraZeneca vaccine and blood clots

The European Union's drug regulatory agency says experts have concluded that the AstraZeneca vaccine is not linked to an overall increase in the risk of blood clots and that the benefits of use outweigh the risks.
The finding from the European Medicines Agency could open the way for European countries that had suspended the use of the vaccine over the past week to resume dispensing the shots.

The head of the EMA, Emer Cooke said Thursday (Friday morning, NZT) that the agency cannot rule out definitively a link between rare types of blood clots and the vaccine, however, and experts recommend raising awareness among doctors and recipients of possible risks.

EMA recommended adding a description of these cases to the vaccine leaflets so health workers and patients would be aware of these rare blood clots.

* EU regulator 'convinced' AstraZeneca benefit outweighs risk
* Covid-19: More European countries hit pause on AstraZeneca vaccine rollouts after reports of blood clotting, Medsafe still assessing for NZ
* Covid-19: WHO says AstraZeneca vaccinations should continue as some nations halt rollout

But Cooke also said: Our scientific position is that is that this vaccine is a safe and effective option to protect citizens against Covid-19.

It demonstrated ... at least 60 per cent efficacy in clinical trials and preventing coronavirus disease.

Millions of people have received doses of the AstraZeneca vaccine.

And in fact, the real-world evidence suggests that the effectiveness could be even higher than that.

Numerous European countries had suspended use of the vaccine over the past week amid concerns over blood clots in a few dozen of the millions of people vaccinated with the formula across the continent.
