We have a dear friend, who had china flu last year....and, had fully recovered....who went on to have the experimental 'vax', on his doc's advice......only to die in his sleep (last week), after his first shot.
Otherwise healthy (no meds) 70 yo, now gone.
We also had a family friend who had CV19 insisted upon getting vaccinated even though he had the immunity already!! Had the vaccine on a Friday and died very unexpectedly on Sat. the day after!! He was also 70!
