That was my non-military experience or knowledge answer, too.
VACCINE...
Received from a friend this morning....
I have a friend from church who just lost her father.
He had the first shot (Moderna) and everything seemed fine, but on the day he had the second shot they were trying to check up on him to make sure he was okay and they could not reach him.
Her brother finally went over to their dad’s house and they found him passed away in bed.
Kathy said the coroner told them they would not do an autopsy unless they thought there was foul play.
The family could pay for an autopsy, but she and her brother talked it over and decided that they were not even sure if they would be able to tell if the vaccine caused his death or, if it did, if they would be told the truth.
Her father did have a heart condition, but had been really active.
It might have been just coincidental, but it really gives you pause for thought.
The family was in shock.
