Imagine a world where life-saving vaccines leave behind a trail of environmental harm. That's the harsh reality of immunization waste, a growing problem in Southeast Asia. But a group of dedicated experts is fighting back. In December 2025, New Delhi became the epicenter of a crucial mission: crafting a practical guide to tackle Immunization Waste Management (IWM) head-on.
And this is the part most people miss: the sheer scale of the issue. Every year, routine immunizations in Southeast Asia reach approximately 37 million children, each receiving at least ten vaccines. Add to that 40 million pregnant women receiving tetanus shots, and you're looking at a staggering 100 million liters of immunization waste annually. What's more, 80% of these vaccinations happen in outreach settings, making proper waste disposal a logistical nightmare.
With the introduction of new vaccines and expanding immunization coverage, the problem is only getting bigger and more complex.
This wasn't just another meeting. Jointly organized by the WHO Regional Offices for South-East Asia (SEARO), South Asia (ROSA), and East Asia Pacific (EAPRO), this consultation brought together a powerhouse team. Experts from India, Nepal, and Thailand joined forces with program specialists from WHO and UNICEF headquarters, regional offices, and country offices across Bangladesh, India, Myanmar, Nepal, Sri Lanka, and Timor-Leste. Their mission? To create a user-friendly, practical guide that empowers policymakers, program managers, and frontline workers to manage immunization waste safely, effectively, and sustainably.
But here's where it gets controversial: How do we balance the urgent need for immunization with the environmental impact of waste? The proposed Regional Practical Guide on Immunization Waste Management aims to bridge this gap, promoting best practices that are both health-protective and environmentally sound. It's a delicate dance, and one that requires innovative solutions and global cooperation.
The guide, titled “Protect Health, Preserve Earth: Manage Immunization Waste Responsibly!”, promises to be a game-changer for Southeast Asia. By addressing the unique challenges faced by each country in the region, it will provide a roadmap for a greener, more sustainable approach to immunization.
