Official Title: Phase 1 Study of the Safety and Immunogenicity of Na-APR-1 (M74)/Alhydrogel® Co-administered With Na-GST-1/Alhydrogel® in Brazilian Adults

Brief Summary: Na-GST-1 and Na-APR-1 are proteins expressed during the adult stage of the Necator americanus hookworm life cycle that are thought to play a role in the parasite's degradation of host hemoglobin for use as an energy source. Vaccination wtih recombinant GST-1 or APR-1 has protected dogs and hamsters from infection in challenge studies. This study will evaluate the safety and immunogenicity of co-administering Na-GST-1 and Na-APR-1 to healthy Brazilian adults living in an area of endemic hookworm infection.
