WHO's Global Vaccination Push Marks Health Milestones
Geneva, Wednesday, 12 February 2025.
The World Health Organization’s strategic vaccination efforts continue to reduce disease risks globally, saving millions of lives annually and showcasing substantial public health advancements.
Historic Achievement in Global Health
The year 2024 marked a significant milestone in global immunization history, with the 50th anniversary of the Expanded Programme on Immunization saving over 150 million lives [1]. Current vaccination efforts continue to demonstrate remarkable effectiveness, with 84% of infants worldwide receiving three doses of DTP-containing vaccines in 2023 [2]. However, challenges remain as approximately 14.5 million children still missed out on basic vaccinations in 2023 [2], highlighting the ongoing need for expanded coverage.
Economic Impact and Investment Returns
Immunization programs have proven to be one of the most cost-effective public health interventions available. Studies indicate that every dollar invested in vaccination yields a return of US $44 when considering broader social and economic benefits [3]. This substantial return on investment has motivated continued support from global health organizations and national governments. The prevention of vaccine-preventable diseases not only saves lives but also reduces the economic burden on healthcare systems and families through reduced medical expenses and increased productivity [3].
Current Initiatives and Future Planning
WHO is actively preparing for future health challenges, as evidenced by the upcoming consultation on influenza virus vaccines for the 2025-2026 Northern Hemisphere season [4]. The organization continues to strengthen its Global Influenza Surveillance and Response System (GISRS), ensuring rapid adaptation to evolving viral threats [4]. Supporting these efforts, organizations like CEPI are currently backing over 50 vaccine candidates and platform technologies [5], while monitoring the estimated $12.5 trillion global economic impact of the COVID-19 pandemic through 2024 [5].
African Region Progress and Challenges
The African region has made significant strides in vaccination coverage, bringing several diseases to the brink of eradication, including polio and maternal and neonatal tetanus [6]. However, the region still faces considerable challenges, with approximately one in five African children not receiving all necessary basic vaccines. This gap results in over 30 million children under five suffering from vaccine-preventable diseases annually, accounting for 58% of global VPD-related deaths [6].
