Sorry to hear it came so close. Hopefully, the family has become wiser.
My uncle confronted his son and his wife who are both full time college professors. The school did not require their 13-year-old son to be vaccinated and boosted... they made him do it. My uncle asked if they thought that the vaccinations might have caused his always healthy and active grandson to have a massive stroke. The two college professors told my uncle that was the stupidest thing that they had ever heard...
So, no not even a massive stoke, brain damage and the near death of their only child made a dent in the faith in the medical authorities of my two genius professor cousins. I should send them an invitation to some of the Covid discussions that we have here. They would fit right in with our cabal of Covidiots.
