Primary health care and immunisation in Iran

Abstract

The Primary Health Care (PHC) network of Iran consists of a rural and an urban branch. While the rural branch presently covers a sizeable portion of the rural population, the urban PHC project is in its early stages of implementation. The Expanded Programme on Immunisation (EPI) in Iran, which started as an independent and vertical project in early 1983, is being gradually integrated into the PHC network as the latter expands. Results of the second PHC programme review of Iran shows that immunisation coverage of children has improved appreciably since the first PHC review, especially for BCG which stands at 56.3%. Complete immunisation at first birthday in the rural areas with the PHC services is 44.1%, whereas for urban areas other than Teheran it is 28.1%. While the high coverage in the rural areas is attributed to the 'active' approach and vigilance of the providers of immunisation (i.e. the community health workers and the vaccinators of the mobile teams), the higher coverage in the capital city of Teheran is attributed to the involvement of private paediatricians and the generally higher social, economic, and educational status as well as higher interest of mothers. It is noticed that the results of cluster sampling for determination of immunisation coverage in large metropolitan areas of the developing world must be interpreted with much care. The reason is that in these areas extreme fluctuations in the crude birth rate are common and therefore results tend to over-represent the attributes of the segment of population with lower birth rate. It is also argued that complete immunisation might not be the best indicator for assessing the progress of the immunisation efforts. These and other findings are discussed in detail. are discussed in detail.
