The military mandated Swine Flu shots in 1976. Damn near killed my grandmother a few months earlier, so I had to scheme my way out of the shot. It was November; I went swimming half a day in the rather shallow but very frigid Wichita River. Got sick as a dog, and was hospitalized for over a week. Deemed to sick to vaccinate and got a 90 day waiver. Program was cancelled by then. Whew!
