But why did some die and others didn't? Don't you think we'd know by now.
My 95 year old father (turns 98 in a month) assisted living facility got Covid I think twice. He did end up in the emergency room following taking the shot. My mother (same assisted living) died during a Covid year. Her doctor had told her she probably had ~6 months (heart & return of cancer), she made it 9+ months. Pretty sure she had Covid at least once, didn't have it anytime near when she died, it was her heart. If she had caught Covid couple weeks before what would have been the cause of death?
Had an uncle died ~year before first Covid from Flu. Hospitals were full of flu patients so they sent him home. Eventually he ended up in the hospital.
That said I also know of a few relatively healthy people who died from Covid.
