Yes, my polio vaccine was administered in a sugar cube. I think it was 1960.
The Salk vaccine, the earthshattering breakthrough that caused worldwide headlines, came first, and was given by injection.
The Sabin vaccine, which came a little later and is apparently more potent, was administered on a sugar cube.
Those of us who were kids back then got both.
I remember how worried my mother was every summer that one of us would get the virus in one of the annual epidemics.
She always said the day they announced the Salk vaccine was the greatest day since the Hiroshima bomb.
There were hospitals with row upon row of iron lungs, keeping kids with polio alive.
