The US Food and Drug Administration (FDA) has not identified a link between Johnson & Johnson’s Janssen Pharmaceutical Division vaccine and blood clots, writes the New York Times.
The FDA said in a statement that the investigation and evaluation of these cases is ongoing.
The agency said it was aware that “some individuals” in the United States had blood clots and low platelet counts after receiving the Johnson & Johnson vaccine. At the same time, it is emphasized that both situations can be caused by different reasons, Agence France-Presse reports.
According to the US Centers for Disease Control and Dissemination (CDC), about 4.9 million people have been vaccinated with the Janssen vaccine in the country.
Earlier it was reported that the European Medicines Agency EMA began to study information on cases of thromboembolic complications in patients vaccinated with Janssen. It was noted that the relationship between these complications and the vaccine has not yet been proven. In total, EMA received data on four such episodes outside the European Union, one person died.
The day before, information appeared that two centers for vaccination of the population against coronavirus with the drug company Johnson & Johnson were closed in the United States due to numerous cases of adverse reactions, including nausea and dizziness.
