This Q&A followed Nigeria’s presentation on sustaining delivery after MAC introduction, with exchanges drawing parallels from the DRC, which introduced HPV vaccination in 2024 and identified similar phase-specific challenges. Nigeria clarified that the large total figure of girls reached combines MAC campaign outcomes (over 12.3 million) with routine and targeted intensification efforts (approximately 2.9 million), noting that facility-level uptake post-campaign remains suboptimal — a pattern it considers common across countries. On Phase 1 challenges, Nigeria highlighted that Lagos State, despite high educational indices, recorded the lowest coverage at 36%, illustrating that vaccine uptake is driven by community perception rather than literacy levels alone. Specific barriers included organized health worker opposition to HPV vaccination amplified through social media, and religious resistance overcome through direct engagement with church leadership — including outreach to a bishop’s secretariat whose letter to congregations meaningfully shifted acceptance. On coordination, Nigeria confirmed that its National Technical Working Group for HPV — established prior to introduction — serves as the unified platform for both traditional (government) and non-traditional partners at national and state levels. On catch-up, Nigeria outlined leveraging existing high-visibility platforms such as the biannual Maternal and Child Health Week, during which over one million girls were vaccinated in a single May round, as the primary sustainable mechanism for reaching missed cohorts.
