Last time I had a hard flu that had me in bed for days was 1977 as a kid. The rest have been minor 24 hr bugs and a few alcohol-related… I’ve gotten flu shots on and off in the last 25 years but I think there will be no more after the COVID scam.
I read an article a few months ago that mentioned having had the flu (one, or, a few times) is the superior way to have long term immunity.
If I can find the article, again, I am going to bookmark it, somehow.
