All the way back in 1976 during the Swine Flu outbreak, fears of a swine flu pandemic had loomed large, so President Gerald Ford had ordered an unprecedented mass vaccination of everyone in the United States. As Wikipedia reported of the disastrous rollout of that vax, after the program began, the vaccine was associated with an increase in reports of Guillain–Barré syndrome (GBS), which can cause paralysis, respiratory arrest, and death. The immunization program was ended after approximately 25% of the population of the United States had been administered the vaccine.
