The US Centers for Disease Control and Prevention said Friday that there is a possible safety issue with the bivalent Covid-19 vaccine made by Pfizer and BioNTech..
The CDC said one of its vaccine safety monitoring systems – a “near real-time surveillance system” called the Vaccine Safety Datalink – detected a possible increase in a certain kind of stroke in people 65 and older who recently got one of Pfizer’s updated booster shots.
“A rapid response analysis” of that signal revealed that seniors who got an bivalent booster might be more likely to have ischemic strokes within the first three weeks after their shots, compared with weeks four through six.
Ischemic strokes, the most common form, are blockages of blood to the brain.
They’re usually caused by clots..
