3. Vaccines
- Major Developers: Louis Pasteur, Jonas Salk, Albert Calmette, Camille Guerin, Edward Jenner, David Smith, Ian Frazier
Vaccines were first implemented by China in the 10th Century to help against smallpox. This expanded when Edward Jenner developed the smallpox vaccine in 1796, however. Louis Pasteur then developed the vaccines for Cholera in 1880, Anthrax in 1881, & Rabies in 1885. Albert Calmette & Camille Guerin together invented the vaccines for Tuberculosis with the Bacillus Calmette-Guérin (BCG) Vaccine in 1922.

However, Albert alone invented the first antivenom for snakebites. Jonas Salk with Thomas Francis invented the first Influenza Vaccine in 1933 while Salk on his own invented the Polio Vaccine in 1952. David Smith made the vaccine for Haemophilus influenza, which often gave infants pneumonia and meningitis. Meanwhile, Ian Frazier invented the vaccine for cervical cancer, genital warts, and anogenital cancers in 2006.
