Other than the smallpox vax,there were NO vaccinations AT ALL when I grew up and most of us survived,but many didn’t.

About 25 years ago, one of my former co-workers received a flu shot, 18 hours later, he was paralyzed. The guy was in his mid 50’s and in excellent health. A couple of years earlier, another co-worker was rushed to the ER after an extreme allergic reaction to a flu shot. He made a full recovery but is very fortunate to be alive.
I’ll pass on the flu shot, thanks.
