Immunization outreach remains essential for reaching zero-dose and underimmunized children. However, it is time to update the Reaching Every District/Reaching Every Community (RED/REC) framework that has guided outreach for two decades to address implementation gaps. Microplanning is often conducted at the district rather than community level, relies on outdated population estimates, and lacks the tracking needed to verify whether the most vulnerable children are being reached. This piece proposes five shifts to modernize outreach: equity-driven targeting rather than blanket coverage rules, predictive AI and dynamic geospatial mapping, triangulated approaches to resolving denominator uncertainty, sustainable domestic financing, and policy that supports local flexibility and community accountability. Together, these shifts point toward a model of precision equity, in which data-driven targeting and real-time accountability could allow outreach to become a more cost-effective, sustainable component of routine immunization services.
