The main objective was to measure coverage of fully immunized child (FIC) using existing prospective data routinely collected by INDEPTH Health and Demographic Surveillance System (HDSS) centres. Three specific objectives were defined:
- Estimate the coverage of FIC by 12 months of age
- Analyse the factors associated with FIC by 12 months of age
- Analyse the impact of FIC on subsequent child survival until 3 years of age
For the first objective, the coverage should be further disaggregated by sex, place of residence, maternal education, and if possible by a wealth quintiles. Furthermore, missed opportunities for immunization; children vaccinated on schedule as well as out-of-schedule and associated factors were studied.
