The START team conducted a review on academic and grey literature, as well as key informant interviews, to identify how gender interfaces with routine immunization activities in 10 focus geographies. These interactions were not limited to equal coverage of antigens, but included the influence of dynamics at the individual, household, community, health system, and policy level. The identified contributing factors and recommendations for ways to improve coverage by targeting gender-specific barriers were synthesized in a report and a slide deck presented to the team.
