My friend, Joyce, whose L arm was paralyzed from polio in 1952; we were in the 6th grade. We took turns visiting her during lunch hour while she was bedridden from polio. Her parents had moved her bed to the living room of their home, which was just a block from school. At our 60th Class Reunion, Joyce's left arm is still paralyzed. I'm glad I can use my left arm and hand and fingers on a keyboard, which Joyce never could. Gwen, a neighbor a year older, got polio that same summer. I couldn't go to her house to play nor could she come to my house because she was bedridden. Gail got off lightly from polio. I don't know that she had any lasting effects. One of the Williams twins had her face paralyzed from polio; she could never smile after that.
"Childhood diseases" can be very serious. Vaccines can save lives and prevent survivors from living with life-long effects.
