Instituto Butantan supplies the Brazilian public health system with 90% of the antivenin and 65% of all vaccines distributed in the country. Out of the 170 million doses of vaccines dispensed annually by the Brazilian immunization program, 100 million are produced Butantan.

In particular, Instituto Butantan manufactures 100% of the influenza vaccine doses used by the Ministry of Health. Presently, we are the largest flu vaccine manufacturer in the Southern Hemisphere. 

The current manufacturing capacity is the result of an internal development of processes to obtain vaccine antigens, as well as technology transfer processes and Productive Development Partnerships between Butantan and external Laboratories.
