I remember the Swine Flu panic-demic of 1977. First and only time I got a flu shot, since I was in the middle of finals I needed to get my BS at the time.
As I recall, the flu shot worked really well. I got the flu shortly after receiving the shot. Luckily, it didn’t interfere with my finals.
I’ve steadfastly refused to get another flu shot in the 43 years since, and I will probably refuse to get one for as long as I’m alive, or at least mentally competent enough to make my own medical decisions.
I called AIDS “the swine flu of the eighties” when it first surfaced. I was a bit off on that prediction but it never became the civilization ending plague it was feared to be.
