“Despite the introduction of highly effective vaccines in the mid-twentieth century, the Global Polio Eradication Initiative, launched in 1988, faced persistent hurdles. In several regions of the Global South, political instability, active military conflict, and deep-seated local suspicions of international agencies disrupted vaccination campaigns. Public health workers struggled to maintain the 'cold chain' necessary to keep vaccines viable in remote areas without electricity. While polio was successfully eliminated from the Americas and Europe, transmission continued to persist in localized pockets of South Asia and Sub-Saharan Africa into the early twenty-first century.”
