The titans of global health are under siege. As the Global Fund and Gavi, the Vaccine Alliance, approach their critical replenishment cycles for 2026-2030, a quiet but powerful chorus of donors is asking the unthinkable: Why do we need two separate giants?

For two decades, these organizations have run parallel tracks—one delivering vaccines, the other fighting AIDS, TB, and malaria. Together, they have saved millions of lives. But in a post-pandemic world of "polycrisis" and shrinking budgets, the inefficiency of maintaining two massive, Geneva-based bureaucracies is drawing fire. The buzzword in donor capitals is no longer "expansion" but "consolidation."

The Efficiency Imperative

The logic for a merger—or at least a radical integration—is financial. Donors are fatigued by the endless rounds of replenishment conferences and duplicate administrative costs. Why have two supply chains, two country coordinating mechanisms, and two monitoring frameworks when the health systems they support are the same? A unified entity could streamline operations, reduce overhead, and present a single, powerful front for disease control.

Rumors of a merger have sparked anxiety within the organizations. Staff at Gavi have already faced voluntary departure schemes as the alliance seeks to slim down preemptively. The fear is that a merger would create a clumsy behemoth, losing the specialized agility that allowed Gavi to roll out vaccines at speed.

Impact on Disease Programs

For recipient countries like Kenya, the stakes are incredibly high. A disrupted merger could stall the flow of bed nets and vaccines. Conversely, a successful integration could simplify the grant application process, allowing Ministries of Health to deal with one partner instead of many.

• The Malaria Intersection: The rollout of the new malaria vaccine—a Gavi mandate—requires close coordination with bed net campaigns—a Global Fund mandate. This intersection is seen as the proof of concept for integration.
• The Sovereignty Risk: A single mega-fund gives donors immense leverage, potentially overpowering the voices of recipient nations.

Whether they merge or merely align, the era of fragmentation is ending. The message from the Global North is clear: Do more with less, or risk losing it all.
