Assessment of vaccine wastage rates, missed opportunities, and related knowledge, attitudes and practices during introduction of a second dose of measles-containing vaccine into Cambodia's national immunization program

Future research should explore the causal links between provider practices related to vaccine wastage and their impact on vaccination coverage.
