I believe it became available in February of 1954. I remember as a kid going with my mother to one of our local public schools to get the shot. What I remember most is a bunch of screaming kids and harried mothers. I'm 64 so I think my mother had taken me around 1961 or 1962, I'm not quite sure but I know I was a young kid. But the polio vaccine was developed from technology from over sixty years ago. We live in a different world today. Heck here we are talking over miles on an electronic communication device that was considered science fiction in 1954.

Oh that may be the difference...tho I read 1955. I had a sugar cube—not a shot...

Polio vaccine has been available since 1955. The inactivated polio vaccine (IPV) was available first, given as a shot, in 1955. A more convenient form, called oral polio vaccine (OPV), was given as liquid drops via the mouth. It was developed in 1961.* May 11, 2020
