A Historic Commitment to Health Security

In a pivotal meeting held on September 8, 2025, health ministers from across West Africa came together in Abidjan, Côte d'Ivoire, to tackle the urgent need for a Lassa fever vaccine. Convened by the West African Health Organisation (WAHO) and co-led by Nigeria's Dr. Muhammad Ali Pate and Côte d'Ivoire's Mr. Pierre N’Gou Dimba, this high-level conference marks a significant step towards combatting a virus that has long plagued the region.

Endemic Threat with No Current Vaccine

Lassa fever, an endemic disease in West Africa, takes a staggering toll on public health and economies, with no licensed vaccines available to protect against it. The most promising vaccine candidate, developed by IAVI with support from CEPI, is currently undergoing trials in Ghana, Liberia, and Nigeria. This represents the most advanced Lassa fever vaccine study globally, offering hope after years of devastation.

Collaboration for a Common Goal

During the meeting, ministers endorsed a communique emphasizing the necessity of accelerating vaccine readiness and reinforcing the region's health priorities. Their united pledge includes supporting IAVI’s rVSVΔG-LASV-GPC vaccine candidate through collaborative funding and coordinated efforts to mobilize resources, thus enhancing both national resilience and regional solidarity against public health threats.

Voices of Leadership

Dr. Pate emphasized the need for a comprehensive approach, stating, "In Nigeria, we are investing in infrastructure such as laboratories and surveillance systems that bolster regional efforts. Our commitment extends beyond Lassa fever; it's a declaration that Africa can unite to enhance global health security."

Dr. Melchior Athanase J. C. Aissi of WAHO reflected on the significance of this collaboration, asserting, "West Africa is ready to lead in addressing Lassa fever and potential pandemic threats. With regional solidarity, we can make a real difference."

A Brighter Future for West Africa

CEPI's Dr. Richard Hatchett heralded this as the closest the region has ever come to a vaccine for Lassa fever, sharing his commitment to advancing this initiative. Meanwhile, IAVI president Dr. Mark Feinberg echoed the sentiment, citing the signing of the communique as a crucial step toward a sustainable health partnership that prioritizes accessible vaccines.

Addressing a Growing Threat

The urgency of this initiative is underscored by alarming statistics: Lassa fever affects hundreds of thousands in West Africa annually, leading to nearly 4,000 deaths and $110 million in lost productivity each year. As environmental shifts raise the stakes, projections suggest that climate change may expose up to 600 million people to Lassa fever by 2050.

A Conference of Collaboration

The ongoing 2nd Lassa Fever International Conference, themed "Beyond Borders: Strengthening Regional Cooperation to Combat Lassa Fever and Emerging Infectious Diseases," seeks to foster dialogue among scientists, public health officials, and policymakers to expedite vaccine development and enhance disease control strategies. This landmark gathering underscores the critical importance of unified efforts in tackling Lassa fever and other infectious diseases.

Conclusion: A Path Forward

The resolution reached at this meeting serves not only as a strategic health initiative but as a testament to the potential of collaborative regional health action. As West Africa stands on the brink of this monumental health advancement, the commitment to vaccine readiness may redefine how the continent safeguards itself against future health crises.
