How we can strengthen vaccination programs and build vaccine confidence together

Two MSD leaders share how we’re working to help protect communities from vaccine-preventable illnesses

February 21, 2024

Vaccines are one of the most significant public health achievements in modern history, playing a vital role in helping to prevent certain infectious diseases and protect communities across the globe.

Unfortunately, the COVID-19 pandemic brought forth a new set of challenges in sustaining vaccination efforts for other preventable diseases — highlighting existing disparities and inequalities in access to health care and underscoring the urgent need for action.

In two op-eds for Devex, an independent news organization covering global development, Drew Otoo, Pharm.D., president of global vaccines, and Alfred Saah, M.D., executive director of scientific affairs, highlighted some of the ways we’re working to address these challenges at the global, national and local levels.

Collaborating to help increase health equity

Otoo said collaboration across sectors is key to building trust, enabling equity and establishing stronger, more resilient vaccination programs.

“Now more than ever, we have an opportunity to evaluate and strengthen our approach… Together, we can help create a more equitable future where vaccines are available to and accepted by all who can benefit from them.”

Otoo shared examples of our work with local and global stakeholders to develop tailored approaches to improve vaccine confidence and supply vaccines for communities that might otherwise be without them:

Local organizations and community leaders have a deep understanding of the issues contributing to inequities and low routine vaccination rates in their communities, and they’re essential to identifying and executing solutions. We know this to be the case from our efforts through ImmUNITY Chicago, an initiative we helped catalyze with local stakeholders to address lower vaccination rates among neighborhoods in the Southwest Side of Chicago, predominantly among communities of color.
Strategic global collaborations are also critical to enabling stronger, more sustainable vaccination programs. We work with Gavi, the Vaccine Alliance — a global alliance that has helped to vaccinate nearly half of the world’s children in low-income countries.

Combating vaccine hesitancy and building trust

Saah emphasized our commitment to addressing vaccine hesitancy (the reluctance or refusal to vaccinate despite the availability of vaccines) and building confidence at local, national and global levels.

“By understanding the knowledge gaps and prioritizing strategies that strengthen how we communicate…we can potentially combat vaccine hesitancy, improve vaccine confidence and make a difference in global public health.”

Despite the well-documented benefits of vaccines, hesitancy is a longstanding public health issue that can result in under-vaccination and global disease outbreaks. The reasons behind vaccine hesitancy are often connected to the 3Cs Model, defined by a World Health Organization strategic advisory group:

Complacency: The perception that vaccine-preventable diseases pose little risk to individuals.
Convenience: The degree to which vaccination services are accessible.
Confidence: The degree to which an individual believes vaccines work, are safe and effective and are part of a trustworthy public health and medical system.

Saah shared some of our efforts to improve vaccine confidence, which include:

Working with collaborators to reach the global population and engage communities through mediums that resonate, such as social media, and through messages that can be delivered by trusted community members.
Building capabilities for our colleagues in local markets to better understand the strengths and vulnerabilities of vaccination programs on a global and national scale.

Continuing our work to improve vaccine access

Despite the challenges ahead, both Saah and Otoo are optimistic about the future.

“Combating vaccine hesitancy is not an easy feat and has been a challenge our global society has faced for centuries,” wrote Saah. “However, these challenges bring new opportunities to improve our approach and be better advocates for ourselves, our families and our communities.”
