Viruses have been used since the time of Edward Jenner in vaccines. Jenner used cow pox viruses to inoculate people against small pox infection. There was great fears about his methods. Some people thought that cows might grow out of their arms. He never used the small pox itself but 'scabs' from cow pox lesions.
