Official Title: Determination of Prevalence and Intensity of Hookworm Infection and Community Preparedness for Hookworm Vaccine Trials in Endemic Areas of Northeastern Minas Gerais, Brazi
Brief Summary: Na-ASP-2 is a protein expressed during the larval stage of the N. americanus hookworm life cycle. In a clinical study in previously hookworm-infected adults in Brazil, this protein induced urticarial reactions (rash) in a subset of volunteers. The clinical trial component of this study involves skin testing for immediate-type hypersensitivity to the Na-ASP-2 Antigen. Both prick-puncture and intradermal tests will be applied.
