Expanded immunisation programme saves over 51 million lives in Africa

The World Health Organization (WHO) estimates that the Expanded Programme on Immunisation (EPI) has saved approximately 51.2 million lives in Africa over the last 50 years. By preventing deaths from various vaccine-preventable diseases, the initiative has fundamentally changed public health across the continent. Within a span of 22 years, the programme is credited with averting 19.5 million deaths from measles alone. The near elimination of maternal and neonatal tetanus further reflects how these efforts have improved health outcomes for the most vulnerable populations.

When the EPI was first established, its goal was to reduce the high number of vaccine-preventable illnesses across the African continent. It has since grown to cover 13 different diseases, making essential vaccinations available to the majority of countries in the region. This expansion has been vital in tackling historical challenges like measles, polio, and tetanus. A major milestone arrived in 2022, when the region was declared free of indigenous wild poliovirus, a result of long-term cooperation between governments and health organizations.

Success relies on a coordinated effort between national governments, international health bodies, and local communities. Together, these groups work to ensure vaccines are accessible to everyone, regardless of location. The WHO report emphasizes that continued investment is necessary to maintain these gains and ensure health equity. By working collaboratively, these organizations have built trust in vaccination efforts, which has helped to increase overall coverage rates across the region.

The impact of the Expanded Programme on Immunisation goes beyond individual lives saved, contributing to more stable communities and stronger economies. Reducing the frequency of preventable illness eases the pressure on healthcare systems, allowing countries to direct resources toward other areas of development. Healthier populations are naturally more productive, as fewer people are sidelined by illnesses that would otherwise prevent them from working and supporting their families.

Looking ahead, the EPI remains a central part of public health strategy in Africa. While obstacles like vaccine hesitancy and reaching remote areas persist, they are being met with new approaches and steady advocacy. The WHO and its partners are focused on keeping vaccination rates high while preparing for new health threats. The evolution of the programme serves as a template for other regions, showing what can be achieved through a sustained and effective immunization strategy.
