Official Title: Randomized, Controlled, Phase 1 Study to Assess Safety and Immunogenicity of Co-administered Hookworm Vaccine Candidates Na-GST-1 and Na-APR-1 Adjuvanted With Alhydrogel® and Gluco-pyranosylphosp

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 with 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 Gabonese adults living in an area of endemic hookworm infection.
