Most who have experienced heart problems, clotting, or other serious side effects are younger than you. But you are sort of right on the edge of the danger zone age-wise.
I’m 60 and started having ‘heart problems’ aka Pericarditis, the week I got the J&J vaxx. I have seven years left until the cells which produce the spike protein which cause my Pericarditis die off.
When I was hospitalized for Pericarditis a technician followed me into a post-stress test recovery room. He told me there were a lot of young people at the hospital in spring with similar issues to mine. That coincided with when the vaxx was approved for teens.
It’s a death vaxx. Time will sort this out. In 20 years many believers-in-the-vaxx will be dead. Sceptics will live. Protect against covid? Forget it. Most deaths are with-vaxx.
