The Linked Immunisation Action Network’s workshop in Istanbul, Türkiye on 3-4 July 2024 brought together government representatives from countries experiencing persistent backsliding in immunisation coverage to discuss and share experiences and challenges, strategies, and good practices for overcoming these challenges to restore coverage. National and subnational government stakeholders from Azerbaijan, Georgia, and Honduras (with Angola participating virtually) were joined by national and regional experts from the World Health Organization (WHO), Pan American Health Organization (PAHO), UNICEF, and Brazil’s national immunisation programme for a productive and engaging learning engagement. This workshop was an opportunity for countries from different regions that have experienced a significant and persistent drop in immunisation coverage in recent years to come together and reflect on the drivers of persistent backsliding. This brief outlines key learnings and takeaways that arose from the workshop.
