The
1976 swine flu outbreak, also known as the
swine flu fiasco, or the
swine flu debacle, was a strain of
H1N1 influenza virus that appeared in 1976. Infectious morbidity was only detected from January 19 to February 9, and were not found outside
Fort Dix. The outbreak is most remembered for the mass
immunization that it prompted in the
United States. The strain itself killed one person and hospitalized 13. However, side-effects from the vaccine are thought to have caused five hundred cases of
Guillain–Barré syndrome and 25 deaths.
