Every year, World Immunization Week highlights a simple yet fundamental fact: vaccines are among the most effective public health interventions ever developed. Over the past several decades, they have prevented millions of deaths, significantly reduced child mortality, and protected populations against many preventable infectious diseases.
The theme of the 2026 edition — “For every generation, vaccines work” — highlights the intergenerational role of vaccination. The benefits of vaccines extend beyond children; they also protect adolescents, adults, and older adults, while strengthening the overall resilience of health systems.
Despite these major advances, several challenges remain. In many countries, vaccination systems face:
- service interruptions;
- inequalities in access;
- the spread of misinformation;
- and a decline in confidence in vaccines in certain communities.
In many parts of the world, including Africa, these challenges have contributed to the resurgence of preventable diseases such as measles and polio.
Building trust in vaccines today requires much more than simply making vaccines available. It involves:
- clear, evidence-based communication;
- a better understanding of community concerns;
- strategic use of data;
- and close collaboration between health authorities, technical partners, and communities.
At CEHPI, we believe that evidence and community trust must go hand in hand. With its expertise in vaccination, epidemiology, real-world data, health communication, and program evaluation, CEHPI is ready to support:
- the Ministries of Health;
- technical and financial partners;
- implementing organizations;
- as well as communities,
in efforts to build confidence in vaccines and support vaccination programs that are stronger, more resilient, and better adapted to local realities.
In a world marked by the emergence of new health threats and the rapid spread of information, investing in vaccine confidence is, now more than ever, an investment in public health and safety.
