Summary

This study tests whether giving a vaccine plus an antibody drug right after high-risk Ebola contact can prevent the disease better than the vaccine alone. About 160 people who have had close contact with an Ebola patient (like touching body fluids or a dead body) will be randomly assigned to one of two groups. The goal is to see which approach lowers the chance of getting sick.
