DR Jeanne during the facebook discussion I learned that it was the sugar cubes that infected a small percentage of people taking it. I had thought you had the Salk injection. Do you remember which it was?
I believe my first two polio vaccines were shots, then we had the sugar cubes. It was my first vaccine that gave me the polio. That was 1956. I later learned that thousands of children died from it. There was a PBS documentary on polio that mentioned this. I believe they used a live virus for a number of years.
You had the cubes after getting sick

Hmm, I read the Salk shot was not live and the Sabin cube was. The FDA approved some manufactures that were not up to standards that very sadly contaminated some of the shipments of the Salk vaccine.
