Background: Campaign integration, which refers to the co-delivery of all or some of the campaign components has been one of the guiding principles of immunization strategies. Mass vaccination campaigns serve as critical interventions to address deficiencies in routine vaccination coverage, particularly within health systems facing challenges. Nigeria has been involved in many mass vaccination campaigns but mostly standalone though attempts have been made to integrate some with other health interventions. In 2019, Nigeria conducted an integrated measles and Meningitis A vaccination campaign in sixteen states in Northern Nigeria. Notably, this marked Nigeria's most extensive integrated campaign, involving the administration of two injectable antigens. This paper aims to chronicle the nation's progress towards the integration of injectable antigens within its immunization framework, drawing insights from the unique challenges and successes encountered during the implementation of this integrated campaign.
Methods:We documented the integration of the measles and Men A campaign from earlier planned standalone campaigns to reviewing decision making steps taken during the planned integration. We reviewed the coordination mechanism involved in the integration as well as the campaign budgets and post-campaign coverage survey report to document best practices, challenges, and recommendations for future integrations. Results: The findings reveal significant time savings, with the integrated approach. Decision-making involved extensive negotiation and collaboration at all levels, with stakeholder engagement crucial for successful integration. Cost-effectiveness analysis indicated remarkable savings in operational costs, attributed to the efficient resource utilization and prudent planning.
Conclusion:Through a detailed examination of this historic initiative, the paper contributes to the understanding of the complexities surrounding the integration of injectable antigens. It addresses the challenges associated with a crowded immunization calendar and resource limitations in developing countries. The lessons learned contributed to the understanding of campaign effectiveness and offered valuable considerations for future integrated health interventions.
