I’m curious if he questions this now.
Some people refuse to believe the possibility that it could harm. My boss for instance is one of the healthiest people I know. Doesn’t really drink, eats super clean, bikes about 300 miles per week, no previous health issues whatsoever.
He got the vax, had a stroke within 4 months. He knows my position and I asked him point blank “is there any part of you that thinks the vax could have potentially played a role in your stroke?” His answer was no chance even though the doctors can’t figure out why it happened.
