In 1976 government officials thought there was going to be an outbreak of swine flu that would kill as many or more than the 1918 flu. (Some good background). They developed a vaccine and these PSA’s were created to convince people to take it. Whoa…Wait ’till you hear about Dotty!
And then all those people died from the shot and the program was suspended. Or at least that’s what my memory tells me.
The program was suspended, but in the end the deaths were not related to the vaccine.
