The European major medicine regulator, the European Medicines Agency, denied on Tuesday finding any direct link between the AstraZeneca vaccine and forming blood clots in adults.
The denial revealed by the agency came after a senior EMA official said that there is a causal link between the vaccine and the presence of blood clots.
EMA said in a statement: “Not yet reached a conclusion and the review is currently ongoing.” It added that the agency will announce more results regarding blood clots concerns on Wednesday.
The agency’s Vaccines department head Marco Cavaleri told Italian media: “We can say it now, it is clear there is a link with the vaccine … But we still do not know what causes this reaction.”
Concerns over the safety of the vaccine are increasing, especially after reporting a number of deaths by rare blood clots in the brain after receiving the vaccine in the UK, and Netherlands.
Moreover, several European countries restricted the use of the vaccine to be only for people who aged over 55 years old.
