I remember it. I came down with it in 1952,-- the peak year for it. Upper back, neck, and shoulders. I was lucky, with the only lasting effect being pisspoor posture but I did see other kids die and remain in iron lungs. Even though that bout supposedly conferred immunity, I took both the Salk and Sabine vaccines when they were offered. While we're mentioning childhood diseases, I also had most all the others,-- mumps, measles, whooping cough, and whatever, but since then I have seldom been sick.
