The Expanded Programme on Immunization (EPI) is a disease prevention activity aiming at reducing illness, disability and mortality from childhood diseases preventable by immunization.

1000 deaths in less than 5 year children will daily occur in Pakistan, if EPI is discontinued. Immunization is one of the most successful and cost effective health interventions. It has eradicated small pox, lowered the global incidence of polio so far by 99% and achieved dramatic reductions in illness, disability and death from diphtheria, tetanus, whooping cough and measles. It is a world-wide Programme being carried out in all countries assisted by WHO, UNICEF and other donor agencies.

The overall objective of the EPI is reduction of mortality and morbidity from the eight EPI diseases by offering immunization services. These diseases are referred as 8 EPI target diseases and cause millions of ailments, disabilities & deaths each year.
