In a recent study published in The Lancet, researchers examined the public health impact of the World Health Organization’s Expanded Program on Immunization (EPI). The establishment of the EPI in 1974 represented a significant commitment to extend the benefits of vaccination to all, aiming to vaccinate children against several diseases. Over the years, the EPI has expanded its scope to provide protection against various pathogens across all age groups, significantly increasing the breadth of protection.
Vaccination has been pivotal in transforming children’s lives by safeguarding them against debilitating and life-threatening illnesses. It has been instrumental in this effort by offering protection against diseases such as measles, poliomyelitis, smallpox, pertussis, tetanus, diphtheria, and tuberculosis, among others, with plans for further expansion to cover more diseases. Moreover, experts have highlighted the potential for vaccines to significantly impact healthy aging and improve the overall health and well-being of older individuals. However, they also acknowledge the challenges that need to be addressed before unlocking their full potential.
Dr. Hamid Jafari, the Director of Polio Eradication in the WHO Eastern Mediterranean Region, emphasized the significant accomplishments of the Expanded Program on Immunization in commemoration of the 50th Anniversary of the program. Since its inception, it has saved 154 million lives, reduced infant deaths by over 40%, and protected millions from disabilities. The EPI, which initially recommended six vaccines, now suggests 13 vaccines across the life course for national programs, underscoring its expansive impact over the last half-century.
As World Immunization Week is commemorated annually, it serves as a reminder of the collective achievements in enhancing global public health over the years. The significant milestones achieved by the Expanded Program on Immunization underscore the positive impact of comprehensive vaccination programs in reducing illness, mortality, and disability across various age groups.
