GSK Expands Vaccine Track with Metro-Level Data—Spotlighting Local Opportunities in US Adult Immunization

Metro-Level Data Uncovers Wide Gaps in US Adult Vaccination Rates

GSK has just taken a significant step forward in the fight against vaccine-preventable diseases with its latest update to the Vaccine Track platform. The new rollout provides metro-area vaccination trends across 387 different US regions, marking the first time public health stakeholders can compare adult immunization rates at such a granular level.

The data uncovers striking differences: while most metropolitan areas showed year-over-year improvement in Q1 2025, about 20% experienced declines. These variations raise critical questions—why are some regions making progress while others are falling behind, and what specific local factors are driving these trends?

A Decade of Insights, Now Localized

Originally launched in 2022 as the only publicly available dashboard for month-by-month adult vaccine trends, Vaccine Track now stretches its reach to include a full decade’s worth of data. Previously focused at state and national levels, the platform’s update means healthcare organizations, policymakers, and community leaders can explore historical and emerging immunization patterns by city, demographic, payer, and access point.

This capability isn’t just about data for data’s sake. With vaccine-preventable diseases costing the US up to $9 billion each year—and 80% of that tied to unvaccinated adults—better visibility could be a game changer for efficient allocation of public health resources.

Disparities Persist, but Opportunities for Targeted Action Grow

The latest CDC figures paint a sobering picture: less than 25% of US adults were up to date on recommended vaccines as of 2022. Vaccine Track’s new metro-area focus highlights not just the scope of the problem, but also where targeted interventions might make the biggest difference. As Leonard Friedland, GSK’s VP and Director of Scientific Affairs and Public Health Vaccines, puts it: these localized insights could help public health partners direct their attention to areas most in need, bridging persistent access and education gaps.

The diversity among metro areas in Q1 2025 trends suggests that local demographics, policy decisions, and healthcare delivery differences likely play an outsized role. Identifying these factors will be crucial to raising immunization coverage nationwide.

Takeaway: Metro Insights Set the Stage for Smarter Local Health Strategies

With adult vaccination rates still lagging nationwide and billions at stake, GSK’s Vaccine Track update delivers more than statistics—it provides public health advocates with the roadmap they need for precision action. The hope is that, as stakeholders analyze trends on the ground, resources can be better targeted and progress more rapidly accelerated.

For anyone invested in improving health outcomes or managing costs tied to vaccine-preventable illnesses, exploring these new local-level data sets may prove an essential first step.
