Instituto Butantan is the main producer of immunobiologicals in Brazil. It is responsible for a considerable percentage of the national production of hyperimmune sera and vaccine antigens, which make up the vaccines used in the National Immunization Program (Programa Nacional de Imunizações, PNI) of the Brazilian Ministry of Health. Our technological development activities in the production of health inputs are associated with the production of vaccines, antitoxins and antivenoms, and biopharmaceuticals for human use.

We export sera and vaccines for over 10 countries in Latin America and Europe.
