For the record, I get a flu shot every year and encourage readers to do the same. Check out My post It’s Time to Get that Flu Shot.
Getting an annual flu shot may be associated with a lower risk of stroke, according to a study published in the September 7, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.

“Studies have shown that getting the flu increases your risk of having a stroke, but research is still being collected on whether getting the flu vaccine can help protect against a stroke,” said study author Francisco J. de Abajo, MD, MPH, PhD, of the University of Alcalá in Madrid, Spain. “This observational study suggests that those who have a flu shot have a lower risk of stroke. To determine whether this is due to a protective effect of the vaccine itself or to other factors, more research is needed.”
