Sadly nothing is risk-free. Even if the vaccine caused his death, would any rational person argue that avoiding the vaccine is the smart decision? 26,500,000 shots in the US have been administered. One died potentially due to the vaccine. There have been 26,500,000 confirmed cases of Covid in the US. Of those 429,000 have died. I'll take my chances with the vaccine. 0.0000004% is is hell of a lot better odds than 0.18%. Obviously the stats aren't perfect and not all cases of covid were identified and quantified but they won't be off by six orders of magnitude.
