Most credible thing I've posted as its coming from someone I know personally who knows them personally. Was surprised to hear it myself personally.
I personally don't doubt that you post what was mentioned to you. I doubt your friend's story.
my wife was a nurse and was very respected because she was a great nurse always went well above what was expected of her. so she gets treated like royalty, I'm not kidding. I'm known not by my name but as her husband, so i get treated well.
having said that we know lots of doctors and nurses. so that's where we get a lot of info.
anyway back to your friend's story. he was already positive so is highly unlikely that he got the vaccine as for more it's reserved for first responders and people in nursing hospitals.
so if he got lucky and got the vaccine and the vaccine got him sick while the actual covid19 didn't. I find that very hard to believe.
