Need for BCG Vaccination to Prevent TB in High-Incidence Countries and Populations

Abstract

An estimated one quarter of persons worldwide are infected with Mycobacterium tuberculosis. In 2018, the World Health Organization issued revised guidance on BCG vaccine for high-risk groups. The World Health Organization should consider guiding countries on a case-by-case basis in developing appropriate BCG policies to deliver equitable healthcare and protect public health.
