Tuberculosis (TB) is a life threatening infectious disease which is prevalent throughout the world. Mycobacterium bovis based Bacille Calmette-Gue´rin (BCG) is the only vaccine available against TB however, this (single) vaccine is not enough to eradicate it.

A double blind community-based randomized trial of amoxicillin versus placebo for fast breathing pneumonia in children aged 2-59 months in Karachi, Pakistan (RETAPP).

Background: Fast breathing pneumonia is characterized by tachypnoea in the absence of danger signs and is mostly viral in etiology. Current guidelines recommend antibiotic therapy for all children with fast breathing pneumonia in resource limited settings, presuming that most pneumonia is bacterial.
