Safety and protective efficacy of synthetic PvCSP vaccine in naïve and pre-immune Colombian volunteers
Objectives
The objective of this study is to compare two groups of volunteers (naive and previously exposed to malaria) vaccinated with three doses of a synthetic derivative of the circumsporozoite protein (CSP) of Plasmodium vivax to determine their protective efficacy.
Malaria Vaccine and Drug Development Center (MVDC), Colombia
This study is a prospective controlled, blinded clinical trial, designed to establish the protective efficacy induced by the vaccine PvCSP between human volunteers with and without a history of malaria. Volunteers will be recruited in Cali, Colombia, and Quibdó, Colombia.
