It was also thought that polio only grew innerve tissues but infected humans produced large amounts ofviruses in their feces, suggesting it also grew in intestines. He received the Robert Koch Medal from Germany,while France named him Chevalier de la Legion d'Honneur. Attempts in the 1930's to use a vaccine prepared from thekilled extracts of infected monkey brains resulted in deaths ofseveral children. Salk thenbegan the crucial human experiments to confirm the resultstaken on monkeys. Hisgreatest reward was the knowledge of being instrumental inthe eradication of a terrible disease.
