^aAverage; ^bWald test; ^cMixed multivariate model included possession of a house, maternal years of schooling and years of residence in urban area. Incomplete vaccine status was defined as not having taken one or more doses required for the first year of life according to the National Immunization Plan adopted between 2005 and 2010. ORV doses were not included in these analysis because they were implemented only after 2006.
