Measles Vaccination Efforts at Risk of Stalling

by Jon Scaccia November 18, 2024

In “honor” of Robert F. Kennedy, Jr., the recent nominee to HHS, let’s take a look at this recent MMWR report. Measles, a disease once a harbinger of widespread illness and death, has met its match in vaccination programs, saving an astounding 60 million lives between 2000 and 2023.

Put that number in your head. It is more than the current population of Italy.

However, despite this tremendous success, the global fight against measles is at a crossroads. Recent reports reveal worrying trends that threaten progress and underscore the urgent need for action.

In 2023 alone, measles cases surged by 20%, and large outbreaks disrupted life in 57 countries—an alarming jump from 36 countries the year before. This spike comes despite vaccination programs, as global coverage of the first dose of the measles vaccine (MCV1) stagnated at 83%, leaving millions of children unprotected. For public health practitioners and researchers, these findings send a clear message: complacency is not an option.

Why Measles Still Haunts Us

Measles is a highly contagious disease capable of causing severe complications, lifelong disabilities, and even death. Its transmission is relentless, requiring high population immunity to interrupt its spread. Yet, the pandemic disrupted vaccination efforts worldwide, pushing coverage rates to their lowest levels since 2008. While some recovery has occurred, vaccination levels remain insufficient to close immunity gaps, especially in low-income and conflict-affected regions.

In countries like the Democratic Republic of Congo and Afghanistan, where fragile health systems already struggle, measles incidence soared to 583 cases per million in 2023—far higher than in wealthier nations. These disparities highlight the urgent need for targeted vaccination campaigns and robust health systems capable of reaching every child.

The Toll of Stagnation

The numbers tell a stark story. From 2022 to 2023, global measles cases climbed from 8.6 million to over 10 million. Yet deaths decreased slightly—from 116,800 to 107,500—because many new cases occurred in regions with lower fatality risks. This data may seem like a silver lining, but it masks the devastating potential of continued outbreaks.

Outbreaks have ripple effects. They strain healthcare systems, disrupt education, and devastate families, especially in vulnerable communities. Every unvaccinated child is a potential link in the chain of transmission, putting their peers, families, and broader communities at risk.

What Needs to Happen Now

Eliminating measles demands more than incremental progress. Achieving and maintaining 95% vaccination coverage for both doses is non-negotiable. Yet, as of 2023, 22 million children still missed their first dose, and second-dose coverage stalled at 74%.

Public health practitioners must prioritize strategies that reach the hardest-to-access populations. This includes scaling up surveillance systems to detect outbreaks early and deploying rapid-response vaccination campaigns to contain them. Programs like the World Health Organization’s “Big Catch-Up” campaign aim to close pandemic-era gaps, but success hinges on collaboration among governments, NGOs, and local communities.

A Call to Action

The good news is that measles elimination is within reach. Vaccination remains one of the most effective public health interventions in history, with a proven track record of saving millions of lives. But the path forward requires a renewed commitment to equity, innovation, and urgency.

Health practitioners and researchers: this is your moment. Strengthen partnerships, advocate for policy changes, and bring vaccination to the forefront of public health discussions. The stakes couldn’t be higher, but neither could the rewards—a world free of measles is possible, and the time to act is now.
