(Washington) A causal link has not been demonstrated at this point between the formation of blood clots and the injection of the COVID-19 vaccine from Johnson & Johnson, the US Medicines Agency (FDA), saying it is to investigate cases in the United States.
“The FDA is aware of information in the United States on serious thromboembolic events, which are sometimes associated with thrombocytopenia (low levels of platelets in the blood), which have occurred in a small number of individuals after receiving a vaccine against COVID-19 for this disease. Janssen, US regulator said in a statement to AFP, citing the name of the European subsidiary of Johnson & Johnson.
“At the present time, we have not found a causal link with the vaccination, and we are continuing our investigation and evaluation of these cases,” the agency added.
She also emphasized, “We will keep the audience informed when we learn more.”
The European Medicines Agency (EMA) said earlier on Friday to investigate the links between the “J&J” vaccine and cases of blood clots.
One case occurred during a clinical trial and three cases occurred during vaccination in the United States. One of them was a killer, “the EMA added.
The US Food and Drug Administration said it was “aware of the EMA press release,” which is “based” on information provided by the US agency to it, “which it received while using the COVID-19 vaccine from Janssen after authorization” in the United States.
The Johnson & Johnson single-dose vaccine was urgently licensed in the United States at the end of February, after two doses of Pfizer / BioNTech and Moderna.
The European regulator has also approved the Johnson & Johnson vaccine, and it is due to begin implementation in the European Union in April.
