Evaluating the Reasons for Partial and Non-immunization of Children in Wushishi Local Government Area, Niger State, Nigeria: Methodological Comparison

Immunization of children against childhood preventable diseases has remained one of the most important cost effective and public health strategies to reduce childhood preventable morbidity and mortalities arising from infectious diseases. A recent report released by World Health Organization (WHO) stated that 1 in 10 infants did not receive vaccination in 2016. Also, a survey conducted in Bida Emirate Area of Niger State Nigeria in 2015 found that full routine immunization coverage in this area was less than 30%. The aim of this study was to establish the full routine immunization status and the reasons for its partial and non-immunization of children in Wushishi Local Government Area using WHO recommended cluster survey method and contrast with Factor Analysis (FA) method to see if the same results were achieved. The findings showed that the full immunization status for this area was very low (36%) and the results of analysis of reasons for failure from both methods seem contradictory. However, it reflected that lack of proper information was strongest for both methods. The disparity obtained in the two methods might be a result of methodological issues. The health implication is that much is expected to be done in the area of enlightenment campaign of the need for  immunization and the need to complete the required basic dose especially in the rural areas.
