Half discover their assumptions were completely wrong. “I ended up being surprised at the answer I got,” confessed one participant in Nigeria’s largest-ever peer learning exercise. In just six weeks, health workers from all 36 states used a simple “five whys” technique to uncover the true root causes of immunization challenges—and the results challenge everything we thought we knew about why global health programs struggle. **🔍 EPISODE HIGHLIGHTS:** **The Surprising Truth:** While experts focus on vaccine hesitancy, systematic analysis revealed the real barriers are often mundane—broken clinic scheduling, data disconnects, and missed opportunities when children visit facilities for other reasons. **The Scale:** Over 4,400 health workers connected virtually across Nigeria’s complex federal system within two weeks. From remote rural clinics to urban hospitals, participants included nurses, community health workers, and local managers who see these problems daily. **The Method:** Using structured “five whys” root cause analysis, each participant identified a local challenge, dug deeper than surface symptoms, and developed practical action plans—all peer-reviewed by colleagues across the country. **The Revelations:** - Only 25% of health workers knew their local vaccination coverage rates, despite collecting the data - Supply-side problems often masquerade as demand issues - Solutions already exist—implementation is the real challenge - “I realized how much I could do with what we already have” **Real Solutions Uncovered:** - Mobile vaccination units partnering with motorcycle taxis - Community drama groups performing health education - Religious leaders using scripture to support vaccination - Simple appointment systems reducing long wait times - WhatsApp networks connecting isolated health workers **The Impact:** One year later, participants continue collaborating without external support, applying the methodology to malaria, disability inclusion, and outbreak response. As one participant noted: “Whatever step I wanted to take, they were almost ahead of me to say, sir, we have learned this and we are going to apply it.” **Why This Matters:** This isn’t just about Nigeria or immunization. It’s proof that the people closest to problems often have the clearest solutions—if we create the right conditions for them to surface and share their knowledge. **Listen to discover:** How peer learning networks can achieve transformative scale faster and cheaper than traditional approaches, and why the biggest barrier to better health outcomes might not be what you think.
