Bangladesh has made significant improvement in health sector, which make it an example for other developing countries even though being a resource poor country. Over the last decades key health indicators such as life expectancy and coverage of immunisation have improved notably, whilst infant mortality, maternal mortality and fertility rates have dropped significantly (Ferdous Arfina Osaman, 2008). Bangladesh stands out as a country that has taken giant steps in healthcare. Long before the emergence of contemporary global health initiatives, the government placed strong emphasis on the importance of childhood immunisation as a key mechanism for reducing childhood mortality. The Expanded Programme on Immunisation (EPI) in Bangladesh is consid- ered to be a health system success because of its remarkable progress over the last two decades. It provides almost universal access to vaccination services, as measured by the percentage of children under 1 year of age who receive BCG (a vaccine against tuberculosis).
