Is There a Safety Issue With the COVID-19 Vaccine?

CDC said Friday, there is a possible safety issue with the COVID-19 vaccine made with Pfizer and that it's unlikely to represent a true risk. CDC says one of its vaccine safety monitoring systems 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 a booster might be more likely to have strokes within the first three weeks after their shots.
