EU regulator reviews Oxford/AstraZeneca COVID-19 vaccine and blood clot links
The world is awaiting a decision from Europe's top medical regulator on whether its initial investigation into whether there is any evidence to show the Oxford Seed Fund/AstraZeneca coronavirus vaccine is linked to a small number of blood clots reported in people across the continent.
The European Medicines Agency's expert committee is set to announce the results of its investigation later Thursday.
Earlier this week, more than a dozen countries including Germany, France, Spain, and Italy suspended immunisation using the Oxford/AstraZeneca COVID-19 vaccine after reports of unusual blood clots in several people among the 17 million people who have received at least one dose in Europe.
Both the EMA and the World Health Organization have said there is no current evidence to suggest the vaccine was responsible, and that the benefits of immunisation far outweighed the potentially small risk of getting vaccinated. AstraZeneca said that after a careful review of its COVID-19 immunisation data, it found no evidence of any increased risk of blood clots in any age group or gender in any country.
On Tuesday, EMA executive director Emer Cooke said the agency's priority was the vaccine's safety, and that it would consider issues including if extra warnings needed to be added for the AstraZeneca vaccine. She noted the daily toll COVID-19 is continuing to take across the continent and said vaccines were critical to stopping its spread.
"We are worried that there may be an effect on the trust of the vaccines," she said, adding, "But our job is to make sure that the products that we authorise are safe and we can be trusted by the European citizens."
The pause in vaccination using the AstraZeneca shot comes as COVID-19 is surging across the continent, and as the UK is expecting major delays in its vaccine deliveries. Tens of thousands of new daily cases have prompted new lockdown measures in Italy caused hospitalisations in France to spike, and led German officials to announce that the third wave of COVID-19 infections has begun.
Any time vaccines are rolled out widely, scientists expect some serious health issues and deaths to be reported, simply because tens of millions of people are receiving the shots.
Determining whether or not the vaccine is to blame can be difficult, since most of the people getting inoculated first are those most at risk of coronavirus. But because there are no long-term data on any of the COVID-19 vaccines, any potential signal of trouble must be thoroughly investigated.
