And there's always the horror stories and legal actions taken against Christians that reject modern medicine and falsely expect God to heal them of whatever comes. Their children suffer terrible tragedies.
I posted this in other threads. It's a short story about not taking the doctors help and expecting God to do everything that man can do for himself:
There was a man in a flood, he made it up to the roof of his house. A boat came by and asked if he needed any help. He replied "No God will save me". So the boat moved on. Two more boats came by and both times the man rejected their help. He drown and died and when he got to heaven he asked God "Why didn't you save me"? God replied: "I sent 3 boats".
That's why I have said pray about it. God may tell someone no, don't get it and tell someone else, like us to get the shot.
People just have to remember that what God tells you is likely for you when it comes to these things and not everyone as a whole.
