Despite the success of vaccines, only one of these diseases â smallpox â has been erased from the globe. Because of vaccines, 12 deadly diseases can be cured including the chicken pox, diphtheria, Invasive H. flu, Malaria, Pneumococcal disease, polio, tetanus, typhoid fever, Yellow fever and smallpox.
Before the vaccine, there were more than 45,000 polio cases in the United States. In just 7 years after the vaccine was declared safe in 1955, there were just 910 reported cases of the disease. Salk never attempted to patent the vaccine.
