The US Food and Drug Administration (FDA) and the US Centers for Disease Control and Prevention (CDC) warned that the updated COVID-19 shot made by Pfizer and BioNtech may be linked to a stroke type in adults, and according to reports, the US CDC continues to advise people to keep up with their COVID-19 vaccinations.
According to the safety monitoring system, a vaccine database maintained by the CDC had discovered a possible safety issue in which individuals 65 and older had a greater risk of having an ischemic stroke 21 days after receiving the Pfizer/BioNTech bivalent shot than they did from days 22 to 44.
Blockages in the arteries that carry blood to the brain are what lead to an ischemic stroke. Ischemia of the brain is another name.
According to the FDA and CDC, this safety issue has not been identified by other large studies, the Vaccine Adverse Event Reporting System of the CDC, databases from other nations, or Pfizer-BioNTech’s databases because it requires additional investigation.
According to the US CDC, it is important to share this information with the public because, the totality of the data currently suggests that it is a true clinical risk.
In a statement, Pfizer and BioNTech said that they have been informed of a few reports of ischemic strokes in people 65 and older after getting the updated shot.
In addition, the companies stated that there is insufficient evidence to draw the conclusion that the use of the COVID-19 vaccines by the companies is connected to ischemic stroke, and that neither Pfizer and BioNTech nor the CDC nor the FDA have observed similar findings across a number of other monitoring systems in the United States or around the world.
According to reports, the CDC and FDA continue to recommend that everyone aged six months and older keep up with their COVID-19 vaccination, despite the fact that this safety concern has not been identified with Moderna’s bivalent shot.
