FG Insists Nothing to Worry About as European Nations Suspend Astrazeneca Vaccinations Over Blood Clot Fears

Seven European countries – Denmark, Norway, Austria, Estonia, Latvia, Lithuania and Luxembourg – have suspended all or part of their AstraZeneca vaccine roll-out as a precaution while they investigate concerns relating to blood clots.

Danish health authorities on Thursday suspended all AstraZeneca vaccinations for two weeks after a 60-year old woman who had been vaccinated formed a blood clot and died.

The move “follows reports of serious cases of blood clots among people vaccinated with AstraZeneca’s Covid-19 vaccine”, the Danish Health Authority said in a statement.

But it cautiously added that “it has not been determined, at the time being, that there is a link between the vaccine and the blood clots”.

Norway soon followed suit, supending all AstraZeneca vaccinations.

Austria earlier announced it had suspended the use of a batch of AstraZeneca vaccines after a 49-year-old nurse died of “severe blood coagulation problems” days after receiving an anti-Covid shot.

Four other European countries – Estonia, Latvia, Lithuania and Luxembourg – have also suspended the use of vaccines from this batch, which was sent to seventeen European countries and consisted of one million jabs.

Spain said Thursday that it has not registered any cases of blood clots related to AstraZeneca’s Covid-19 vaccine so far and will continue administering the shots.

Spanish Health Minister Carolina Darias said she had been informed of cases of blood clots among recently vaccinated people in Austria, but added that “so far, no causal relation between the vaccine and the blood clot events has been established”, and the European Medicines Agency (EMA) was evaluating the situation.

On Wednesday, EMA, Europe’s medicines watchdog, said a preliminary probe showed that the batch of AstraZeneca vaccines used in Austria was likely not to blame for the nurse’s death.

As of March 9, twenty-two cases of blood clots had been reported among more than three million people vaccinated in the European Economic Area, the EMA said.

Some health experts said there was little evidence to suggest the AstraZeneca vaccine should not be administered and that the cases of blood clots corresponded with the rate of such cases in the general population.

“This is a super-cautious approach based on some isolated reports in Europe,” Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene and Tropical Medicine, told REUTERS.

“The problem with spontaneous reports of suspected adverse reactions to a vaccine are the enormous difficulty of distinguishing a causal effect from a coincidence,” he said, adding that the Covid-19 disease was very strongly associated with blood clotting.

AstraZeneca on Thursday said the safety of its vaccine had been extensively studied in human trials and peer-reviewed data had confirmed the vaccine was generally well tolerated.
