Jacinto Convit García (11 September 1913 – 12 May 2014) was a Venezuelan physician and scientist, known for developing a vaccine to prevent leprosy and his studies to treat cancer.

He played a role in founding Venezuela's National Institute of Biomedicine and held many leprosy-related positions.

[1] Convit began his studies in the Caracas School and continued in the Andrés Bello lyceum.

Inspired by people with leprosy, he entered medical school at Central University of Venezuela (UCV) in 1932.

[6] In 1976, Convit was elected Director of the Pan American Research and Training in Leprosy and Tropical Diseases.

Venezuela's National Institute of Biomedicine soon published a note clarifying that they have been working for the previous three years on a vaccine against cancer and it is still in development.

A sample of the tumour mixed with formalin and BCG marks the malignant cells so the immune system might react and attack the cancer.
