Identify the possible cause of thrombosis in people vaccinated with AstraZeneca – Telam

Pan American Health Organization: “There is no indication that the events were caused by the vaccine.”

Scientists from the German University of Greifswald claimed on Friday that they discovered the reason why some people vaccinated with the preparation of the laboratory AstraZeneca have suffered cases of cerebral thrombosis and explained that it triggers a defensive mechanism in the body that activates the platelet reaction.

The specialists asked the Paul Ehrlich Institute, responsible for approving vaccines in Germany, samples of patients with thrombosis after being inoculated and after examining them “they determined that the vaccine triggers a defensive mechanism in the body of patients, which activates the action of platelets, ”German broadcaster Deutsche Welle reported.

They also explained that platelets work in the blood to prevent bleeding, but when they overflow they form clots or thrombi.

“Under normal conditions, platelets are activated when a wound occurs, to cause the wound to heal. However, in some patients, the AstraZeneca vaccine triggers this reaction out of control, causing blood clots to form in the brain.” , added the news. report.

PAHO has recommended that the AstraZeneca coronavirus vaccine “continue to be used” in recognition that the benefits of the vaccine outweigh its risks. ““

One of the methods they are evaluating to deal with this problem and its potential effects is to use drugs that prevent thrombosis, but they explained that this can only be done after the reaction has started, not before.

The University of Greifswald noted that the discovery was possible thanks to the cooperation of the Paul Ehrlich Institute and Australian doctors, where a nurse died after being immunized with the AstraZeneca vaccine.

The Pan American Health Organization (PAHO) recommended on March 16 that the AstraZeneca coronavirus vaccine “continue to be used” with the understanding that the benefits of the vaccine outweigh its risks “to make facing Covid-19, while “the cases presented in Europe are being studied” for the appearance of coagulation disorders.

In a statement, the body of the World Health Organization (WHO) said that “so far”, the Pharmacovigilance Risk Assessment Committee of the European Medicines Agency (PRAC) “did not find a cause and effect relationship between vaccination and bleeding disorders, which can arise from different causes.”

“These events can occur in people who have already been vaccinated, as well as in those who have not yet received the vaccine,” said the international organization and said that “to date, the PRAC has assessed that the The incidence of thromboembolic events in the vaccinated population is not greater than that of the general population “.

“It is important to clarify that vaccination against Covid-19 does not reduce deaths from other causes, even after vaccination”“

In this sense, he said that the Global Advisory Committee on Vaccine Safety (GACVS) of the WHO “assesses the data provided by the European Medicines Agency (EMA), associated with the distribution of two lots of AstraZeneca vaccines, manufactured and distributed in Europe”.

“The director of this agency recently said that there was no indication that the events were caused by the vaccine,” PAHO stressed in the text, and noted that “it is important to clarify that vaccination against Covid-19 does not reduce deaths from other causes, even after vaccination. ”
