Britain’s Medicines and Healthcare Products Regulatory Agency said that the evidence does not indicate that the AstraZeneca vaccine to prevent Covid-19 causes blood clots, but added that an investigation is being conducted into a very rare and special type of blood clot in the veins of the brain.
The agency stated: “The evidence that we have does not indicate that the occurrence of blood clots in the veins is due to the AstraZeneca vaccine to prevent Covid-19.”
She added: “An additional detailed review is underway, while we have reported 5 cases in Britain of a very rare and specific type of blood clots in the veins of the brain and accompanied by a decrease in the number of platelets.”
For its part, France, Germany, Spain and Italy announced that they were awaiting the results of the investigations of the European Union (European Medicines Agency) into reports that a small number of vaccine recipients had blood clots.
The European Medicines Agency is due to release its results on Thursday.
The agency said on Tuesday it was still “deeply convinced” of the benefits of AstraZeneca. Its president, Imer Koc, indicated that the cases of blood clots reported by some countries were relatively common among the general population.
