Background: The Expanded Program on Immunization (EPI) was initiated by World Health Organization (WHO) in 1974 in order to save children from life threatening, disabling vaccine-preventable diseases (VPDs).

However, despite the efforts of government and WHO, this program has not received the amount of success that was desired.
