By comparison, I’ve never had a flu shot in my 60 years. I’ve only gotten the flu two or three times over that period ... and not at all for the last 20 years or so.
Guess I’ve had incredible luck ..,
... or the odds of getting the flu are pretty small ;-)
No, it's called "herd immunity." You just spend most of your time in circles of people who are vaccinated. Since they don't get sick, you don't either. However, depending upon the virus, once the "herd" vaccination rate drops below a certain percentage, members of the herd will contract the virus at an alarming rate. This happened in NYC with red measles some years ago. Until it happened, the measles hadn't been seen for decades in school children, and most of the doctors didn't even know what they were looking at until it was at alarming proportions. By not getting vaccinated, you are weakening the health potential of your "herd."
