You are obviously highly intelligent and well informed.
See Ya in Paradise.
I am at age 81, had 2 shots of Moderna 6 months ago, and as healthy as ever.
Word of caution, 1 month later I got the 2nd shot, I felt tired like a cold is coming on, for one day, on next day after 2nd shot. That was it. No other adverse side effects since.
To make you feel more at ease, latest death rate after vaccine is running at around 0.005% = 99.995% safe.
