VoICE Immunization Evidence
Missed opportunities in full immunization coverage: findings from low- and lower-middle-income countries
Families who access the health system for non-vaccine services are more likely to have fully immunized children. Non-vaccine related healthcare encounters serve as opportunities to vaccinate children.
A study of 14 geographically diverse countries with a DPT vaccination rate below 70%, evaluated missed vaccination opportunities. Researchers found that children – and their mothers – who were fully immunized were more likely to have received other health interventions. In Cote d’Ivoire, children of mothers who had four or more antenatal care (ANC) visits were 54% more likely to be fully immunized than children of mothers who had no ANC visits. Large differences in full immunization coverage were also found in children who received Vitamin A vs. children who didn’t (greatest difference of 41% was noted in the DRC) and in mothers who had access to a skilled birth attendance (36 % difference in Nigeria) and postnatal care (31% difference in Ethiopia), as compared to mothers without access to these services.
