Aid cuts threaten African vaccination progress.

Vaccinations in Africa have saved over 50 million lives over the past five decades, but progress is uneven and under threat. Key achievements include the eradication of wild poliovirus and the introduction of malaria vaccines. However, a sharp 40% cut in U.S. overseas aid following President Trump's 2025 return has disrupted clinics and cold-chain systems. Experts warn that relying on foreign donors is unsustainable and urge African nations to increase domestic health spending to safeguard immunization efforts.
