My father is going for his vaccine on Monday. I have said mu piece, given him every opportunity to see evidence this is not a wise course of action.
Sad, but I have to accept his choice and let fate do its thing.
I'm in the same position having warned my 80 yo parents about the serious evidence based concerns about the vaccine. They both go for the 2nd dose in a couple of weeks. I can only pray that they'll be okay in the near term and not suffer future illness that could result.
