Abstract
Tuberculosis is a major world public health problem. In 2011, approximately 30% of the world’s population was thought to be infected with Mycobacterium tuberculosis, with more than 1 million deaths attributed to this organism.
BCG vaccine, which contains a live attenuated Mycobacterium bovis strain, is part of the vaccination schedule of several countries worldwide since 1960. Because BCG vaccine has been considered as part of efforts to control tuberculosis, billion doses were applied and it remains one of the most widely used of all current vaccines worldwide. So, million newborns are vaccinated every year through national childhood immunization programs, because in several countries around the world it is administered to all children during the neonatal period.
