Salk did not find the cure. He ripped off his peer's work and passed it off as his own with the help of the Jewish Media.
Look at the people in the background.
Basically the kike took home the polio papers home and "lost them". He miraculously was able to rewrite them even though he barely contributed to the work.
An egotism appeared that seemed not to have been evident before. The strongest charge leveled against the young superstar was his inability or unwillingness to share credit for an accomplishment that was felt by his colleagues to be the culmination of the work of so many others. Salk ignored even those who toiled in his own laboratory at the University of Pittsburgh. Perhaps most unforgivable to the scientific community was his lack of acknowledgment of the contribution of Dr. Isabel Morgan of Johns Hopkins, who, between 1945 and 1950, had accomplished the crucial step of immunizing monkeys against polio by using a vaccine made with virus that had been inactivated, or "killed," with formalin. By doing exactly the same thing in humans, Salk was only taking the next logical step in the journey begun by Morgan and others. None of those who had established the principles and the practices upon which the new vaccine was based was granted a share in the public acclaim.
Salk paid dearly for letting himself succumb to fast fame. Within three weeks of the day of celebration, some 4 million children had received doses of his vaccine, prepared by a total of five commercial laboratories. By late April, 200 cases of polio with eleven fatalities had been traced to a faulty vaccine made by Cutter Laboratories of Berkeley, California. There would be many more the following year. Accusations flew in all directions, but Salk was able to overcome those directed at him. What he was not able to overcome was the fact that his transformation from promising young virology researcher to the conquering hero of polio did not sit well with his colleagues.
Although the publicity must have been a factor, the real reason Jonas Salk was never fully accepted by those whom he would have liked to consider his peers is simply that the scientific quality of his contribution was not thought to be great. When a Nobel Prize was to be awarded for the solution of the polio challenge, it went not to Salk but to John Enders, Thomas Weller and Fred Robbins, who had enormously magnified the field's potential by devising the method of growing the virus in a culture medium other than nervous tissue, a magnificent achievement without which continuing research progress would not have been possible. Even the distinction of being elected to the National Academy of Sciences eluded Jonas Salk because that pantheon of investigators did not think his career merited it.
Compared to establishment figures such as Enders, Francis, Paul and Sabin, Salk was a Jonas-come-lately. His only previous noteworthy contribution was his work with Francis on an inactivated-virus influenza vaccine. Since the basis for his polio studies had been so well constructed by others, it was felt by those close to the field that Salk had overcome no great obstacle. In later years, his bitter rival Sabin would tell the medical historian Saul Benison, "You could go into the kitchen and do what he did." Despite the flagrant exaggeration of Sabin's comments, they seemed to echo the sentiments of other scientists as well.
