No correlation, I was born in 57, never had a shot, never had the flu. Staying away from children helps, they are germ farms if they go to public school.
You would have been able to produce antibodies at 11 years of age to the 68 flu. That adds evidence. My kids are in public school, they have gotten a mild flu from the vaccine. I stayed cooped up with them for a week two years ago. I did not get the flu. So, anyway, I am interested in this 68 flu.
