“Guillain-Barre became known during the early 1980’s due to a Swine Flu vaccine IIRC.”
That happened when Ford was President so it was a bit earlier.
The vaccine was rushed to market by the CDC IIRC.
I was just going on known cases in my area. It was odd. About the time TM hit my wife GB hit two other persons and this was new to the Neurologist because it hadn’t shown up yet. GB like TM can be triggered by many sources but GB seems to be more linked to flu virus and flu vaccine. IOW a Flu exposure it seems could just as likely trigger it.
1973, at least at my high school.
