World Immunization Day 2024 Highlights Importance of Global Vaccine Access for Health Security

World Immunization Day 2024 is shining a spotlight on the critical role that global access to life-saving vaccines plays in ensuring health security worldwide. The World Health Organization (WHO) announced that an estimated 51.2 million lives have been saved through vaccines in the African region alone over the past 50 years. "Vaccination against 14 diseases has directly contributed to reducing infant deaths by 40% globally, and by more than 50% in Africa," said WHO Director-General Dr. Tedros Adhanom Ghebreyesus.

The WHO's Expanded Programme on Immunization (EPI), launched in 1974, has been a global endeavor to ensure equitable access to life-saving vaccines for every child. However, the African region still faces challenges in achieving and sustaining high immunization coverage rates, with significant inequities in vaccine access across the continent. The disruptive impact of the COVID-19 pandemic has further strained immunization efforts, and the region is yet to fully recover.

A landmark study published in The Lancet reveals that global immunization efforts have saved an estimated 154 million lives over the past 50 years, with the vast majority being infants. The measles vaccine alone accounted for 60% of the lives saved due to immunization. While immunization coverage has increased significantly, with 84% of infants receiving 3 doses of the DTP vaccine, there are still 33 million children who missed a measles vaccine dose in 2022.

Why this matters: The immense impact of vaccines in saving lives and promoting health security globally underscores the importance of protecting immunization progress. With 67 million children missing at least one vaccination during the COVID-19 pandemic, efforts to increase immunization coverage and ensure equitable access are more vital than ever.

To address these challenges, the WHO, UNICEF, the Gavi vaccine alliance, and the Bill and Melinda Gates Foundation have launched a joint campaign called 'Humanly Possible' to scale up vaccination programs worldwide. "In just over two decades, Gavi has protected over a billion children, helping halve childhood mortality in the world's poorest countries," said Gavi CEO Dr. Sania Nishtar. UNICEF, a major vaccine procurer, works to distribute vaccines to remote and underserved communities, with the goal of protecting more people from vaccine-preventable diseases.

World Immunization Day 2024 serves as a reminder of the remarkable progress made in global vaccine coverage and the life-saving impact of immunization programs. While challenges remain, including the rise of anti-vaccination movements and misinformation, global health leaders are committed to advocating for and funding vaccines to save millions more lives in the coming years. As Dr. Tedros stated, "Continued research, investment, and collaboration are vital to sustain this progress and ensure everyone everywhere has an equal opportunity for a safe and healthy future."
