Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this research is to find out if a single dose of pre-travel vaccination with BCG can lessen tuberculosis (TB) infection by producing an immune response when given to adults traveling to countries with a high or moderate burden of TB. BCG will be compared with a placebo (an inactive vaccine). BCG (Japan) is used globally but is not approved for use in the United States, therefore it is considered experimental. Participants choosing to take part in this research study, will be randomly assigned (this is like a coin flip) to BCG or placebo. 2000 eligible volunteers will be enrolled.
