This refers to the invention of modern epidemiology, owing to the cholera outbreak of 1854. The discovery of tuberculosis and malaria-causing micro-organisms came in 1882 and 1880, respectively. In the 1920s, the innovations of curative and preventive restrictions on penicillin and the BCG tuberculosis vaccine were seen in the 20th Century. The attempts to eradicate smallpox with the previous cases recorded inevitably increased the expectation in 1977 that other diseases could also be eliminated.
