When was the Salk polio vaccine first used on school children in America?

The inoculation campaign that used the Salk polio vaccine during the polio epidemic first started in Pittsburgh, Pennsylvania, in 1954.

Dr. Jonas Salk, the developer of the vaccine, himself was involved in the first program of mass inoculation.

The oral polio vaccine, developed in 1956 by Albert Sabin, became more widely used than inoculations.
