Academic and Research Achievements: Jacob John taught undergraduate and postgraduate students in CMC. He established India's first diagnostic virology laboratory and conducted pioneering research on infectious diseases, clinical virology, vaccinology and epidemiology. He detected high risk of post-transfusion hepatitis B (HB) in 1972 and established donor screening for recipient-safety. He documented world's first 'vaccine-failure' polio cases despite 3 doses of live vaccine, and showed several ways to improve vaccine efficacy, including 'pulse vaccination'. His model of polio control in Vellore and North Arcot district became the forerunner of global polio eradication. He showed superior efficacy of Salk polio vaccine during 1970s and 80s. He established a retrovirus laboratory and field unit and, in 1986, detected HIV infection among sex workers, first in India. He guided opening of HIV sentinel surveillance in all states by ICMR Task Force and instituting donor blood screening for HIV.
