De Souza also ded that it is important to have fear because fear keeps people on ir toes and prevents m from making mistakes. snakes that are kept in Institute are fed a diet of mice and rats that are bred in institute. After extracting vem a small amount is given to horses to trigger a reaction by immune system that produces antibodies that attack toxins. Blood is later extracted from horses and antibodies are harvested into antivem that is used to save lives.
According to Butantan project manr, institute serves as only source of anti-vem for Brazil and it produces almost 250,000 vials of anti-vem a year.
