Doses of oral polio vaccine are added to sugar cubes for use in a 1967 vaccination campaign in Bonn, West Germany. During the race to develop an oral polio vaccine, several large-scale human trials were undertaken. By 1958, the National Institutes of Health had determined that OPV produced using the Sabin strains was the safest. [43]
A color change from red to yellow indicated the presence of healthy cells in the test tube, and thus that the vaccine had produced antibodies in sufficient, protective amounts. Ward discovered that the experiment was successful when she entered the lab early one morning in mid-September 1952 and saw the yellow dye within the tubes at her station.

The Oral polio vaccine AIDS hypothesis (OPV AIDS) is a now-discredited hypothesis which argued the AIDS pandemic originated from live polio vaccines prepared in chimpanzee tissue cultures, accidentally contaminated with simian immunodeficiency virus and then administered to up to one million Africans between 1957 and 1960 in experimental mass vaccination campaigns.
