West Africa launches innovative roadmap to ensure equitable access to Lassa fever vaccines

NIGERIA—West Africa has achieved a significant milestone in regional health security with the official launch of the Lassa Fever End-to-End (E2E) Access Roadmap.

This pioneering framework is the first regionally led initiative to ensure equitable access to safe and effective Lassa fever vaccines once approved.

The Coalition for Epidemic Preparedness Innovations (CEPI) supported the development of this roadmap, while the West African Health Organisation (WAHO) provided leadership throughout the process.

This collaboration demonstrates a unified commitment to strengthening epidemic preparedness, advancing vaccine equity, and building long-term health security across the region.

Lassa Fever continues to pose a persistent public health threat throughout West Africa.

The disease claims thousands of lives each year while placing enormous pressure on already fragile health systems.

Beyond the human toll, affected countries experience substantial socio-economic losses that ripple through communities and national economies.

Several promising Lassa Fever vaccine candidates are currently advancing through the development pipeline.

However, stakeholders emphasize that scientific progress alone cannot guarantee meaningful impact on the ground.

The region has learned valuable lessons from previous epidemic responses, which revealed critical gaps in planning and distribution systems.

The roadmap prioritizes early and intentional planning to address these challenges head-on.

By focusing on uninterrupted vaccine supply chains and equitable access mechanisms, the framework ensures that countries can prepare thoroughly before vaccines are licensed.

This proactive approach marks a departure from reactive strategies that characterized earlier health crises.

Emma Wheatley, Executive Director of Access and Business Development at CEPI, highlighted the historic significance of this moment.

She noted that Lassa fever has affected people’s lives and livelihoods across West Africa for decades, but the situation is now changing.

With experts anticipating the first Lassa vaccine approvals within the next five years, preparations must begin immediately to maximize readiness and impact.

The Lassa Fever E2E Access Roadmap establishes a comprehensive, regionally driven approach that connects every critical stage in transitioning a vaccine from development to sustained, widespread use.

The framework encompasses research and development, regulatory and policy preparedness, manufacturing and supply planning, financing mechanisms, procurement processes, delivery systems, and long-term sustainability measures.

By clearly mapping responsibilities, timelines, and decision points across this entire continuum, the roadmap provides governments, funders, developers, manufacturers, and implementing partners with a transparent framework.

This structure supports timely, affordable, and equitable access to Lassa fever vaccines, particularly in endemic countries where the disease burden remains highest.

Regional bodies, national governments, technical specialists, civil society organizations, manufacturers, and global health partners all participated in extensive consultations that shaped the roadmap.

West African leadership and country ownership remained central throughout the design process, ensuring the framework reflects authentic regional priorities and realities.

Dr. Virgil Lokossou, Director of Healthcare Services at WAHO, emphasized that ending the Lassa Fever threat requires early, deliberate actions grounded in robust regional preparedness and sustained, trusted partnerships.

He described the roadmap as a decisive step forward that enables West Africa to define its own vaccine access priorities while aligning countries, partners, and institutions around a shared vision with complementary roles.

The Lassa Fever E2E Access Roadmap extends beyond mere planning documents to serve as a compelling call to action for sustained collaboration and investment.

The framework signals West Africa’s determination to achieve readiness before vaccines become available, deliberately avoiding the delays that have undermined responses to past epidemics.

By strengthening coordination across the entire health ecosystem and guiding comprehensive preparedness efforts, the roadmap establishes a solid foundation for equitable vaccine access and stronger epidemic readiness throughout West Africa and beyond.
