You're pretty good at copying and pasting from 3 letter agencies' front page articles. A 50YO being hospitalized from a stroke is extremely rare.About 795,000 people in the US have a stroke each year.
That's 2,178 every single day.
"In 2010, hospitalization rates per 10,000 population for stroke for males and females increased with increasing patient age. For males, the rate per 10,000 ranged from 14.7 for those aged <65 years to 285.7 for those aged ≥85 years"
14.7/10k = 0.15%
This isn't perfect data, the age range is way too big. The risk for a 50YO is higher than 0.15%. But the bottom line is many stroke studies I found don't really start tracking until age 65 when the percentages increase significantly.
I'm not saying this is related to the vaccine, I'm saying telling everyone how many strokes occur in a year is worthless. We don't know, and probably won't know for sure why. We need to watch data trends on things like heart attacks, strokes and all-cause mortality over the next few years.
But a recently boosted 50YO Senator going to the hospital with a stoke is a potential data point. We shouldn't draw conclusions either way, we should just pay attention.
