 The study evaluated missed opportunities for vaccination, MOV, in Xijiang province using WHO global methodology, finding that 12.6% of children were still under vaccinated and 54.2% had a MOV, with factors such as age, previous vaccination behavior, caregiver relationship to children, and education level impacting the incidence of MOV. The study suggests that interventions targeting health workers in health service settings could be a potential quick win for improving coverage and equity.
