Yellow fever vaccination in Belem, Brazil Yellow Fever Vaccination in Belem, Brazil. 1930s. Photographic prints.

A family about to travel into the Amazon forest is inoculated against yellow fever. Although Brazil and most of its neighboring republics have eradicated the mosquito vector of the urban form of this dreaded disease, inoculation with 17D virus vaccine is the only protection against the jungle form, which persists among primates and tree-living mosquitoes in the tropical rain forests of Latin America.
