Abstract

Invasive pneumococcal disease remains a major cause of childhood morbidity and mortality in developing countries. In Ecuador, the implementation of the 10-valent pneumococcal conjugate vaccine (PCV10) and the recent upgrade to PCV13 in 2025 represent historic milestones in child health care and protection. This article compiles evidence published between 2021 and 2025 on the impact of this vaccine on national health, morbidity and mortality, and cost-effectiveness in the national health system. The information collected shows a significant decrease in the frequency of pneumonia and preventable complications. However, ensuring its coverage in the country and monitoring for serotypes not covered by it remains a challenge for future generations. In conclusion, the transition to PCV13 represents a significant epidemiological change, and employing reinforcement strategies and equity in access are key to success in prevention and pediatric health promotion.
