Vital Brazil Mineiro da Campanha, known as Vital Brazil (Portuguese pronunciation: [vita? b?azi?]; April 28, 1865 – May 8, 1950) was a Brazilian physician, biomedical scientist and immunologist, known for the discovery of the polyvalent anti-ophidic serum used to treat bites of venomous snakes of the Crotalus, Bothrops and Elaps genera.
He went on to be also the first to develop anti-scorpion and anti-spider serums.
He was the founder of the Butantan Institute, a research center located in São Paulo, which was the first in the world dedicated exclusively to basic and applied toxicology, the science of venomous animals.
