Diphtheria, Pertussis and Tetanus (DPT) are the vaccine preventable diseases of childhood. The published literatures and reports related to DPT immunization coverage are relatively more than DPT diseases. The striking reduction in deaths and in the incidence of these diseases has been closely associated with the introduction of speci¿ c vaccination program. Expanded Program on Immunization (EPI) is a priority program in the country. Nepal has been running country-wide immunization program since 1989. However, there is no doubt that the program has contributed signi¿ cantly towards reduction of infants and child mortality. Effective and ef¿ cient surveillance system and strengthening the routine immunization against DPT are the key steps for elimination of DPT diseases.
