As measles vaccination rates decline across the United States, outbreaks are becoming more frequent — and more expensive. New research suggests the economic toll could climb into the billions annually if coverage continues to slip.
The Rising Cost of Falling Vaccination Rates
A new analysis from the Yale School of Public Health estimates that if measles vaccination rates drop just 1% per year over the next five years, the U.S. could face $1.5 billion annually in costs.
Researchers projected:
- $41.1 million per year in direct medical expenses
- $947 million for public health response efforts such as surveillance and contact tracing
- $510.4 million in lost productivity
Dr. Dave Chokshi of the Common Health Coalition, which partnered on the report, said outbreaks ripple through the entire health system.
“It’s not just hospital care,” he noted. “It’s public health staff pulled from other duties, workers missing paychecks, and systems stretched thin.”
Local Health Departments Strained
In early 2025, when measles spread through West Texas, local health leaders struggled to secure emergency funding.
Katherine Wells, who heads Lubbock’s public health department, requested about $100,000 to hire temporary help for contact tracing and outbreak response. Instead, existing staff worked extended hours as exposures mounted in pediatric offices, urgent care centers and day cares.
Stopping measles requires rapid action:
- Identifying every exposed person
- Verifying vaccination status
- Enforcing quarantines
- Setting up emergency vaccine clinics
Even small outbreaks are costly. A recent preprint study from the Johns Hopkins Bloomberg School of Public Health found:
- The initial community cost of an outbreak averages $244,480
- Each additional measles case adds about $16,000
- A 50-case outbreak can reach $1 million
In 2019, Clark County, Washington, saw 72 measles cases. Officials brought in reinforcements from multiple jurisdictions to manage quarantines and contact tracing. Productivity losses alone exceeded $1 million.
A Preventable Expense
Measles was declared eliminated in the U.S. in 2000, but declining immunization rates now threaten that status.
Since 2019, more than two-thirds of U.S. counties have reported notable drops in vaccination coverage. In many areas, measles-mumps-rubella (MMR) rates have fallen below the threshold needed for herd immunity.
During his second term, President Donald Trump has emphasized “personal choice” in vaccination decisions. Health Secretary Robert F. Kennedy Jr. has also avoided forceful pro-vaccine messaging.
In the first two months of 2026 alone, more than 1,000 measles cases have already been confirmed — nearly half the total reported in all of 2025. About 94% of infections were among unvaccinated individuals.
State-Level Battles
South Carolina is currently facing the nation’s largest outbreak in more than a generation, with at least 1,000 cases centered in Spartanburg County. The state received $100,000 in federal support for vaccine-preventable disease response and redirected several hundred thousand dollars from other emergency funds.
A senior official said the Centers for Disease Control and Prevention sent $8.5 million over the past year to seven outbreak areas nationwide.
But public health leaders say funding often arrives slowly — and rarely covers the full cost.
The Costs You Can’t Measure
While economists can tally medical bills and lost wages, the human toll is harder to quantify.
More than 1 in 10 measles patients in recent outbreaks have required hospitalization, according to the CDC. Complications can include pneumonia, brain inflammation (encephalitis), seizures and long-term neurological damage.
In rare cases, measles can cause subacute sclerosing panencephalitis — a fatal brain disorder that may emerge years after infection.
Two young girls in Texas, ages 6 and 8, died within weeks of contracting measles last year.
“Behind every number is a child struggling with a devastating illness,” Chokshi said. “And often, it’s entirely preventable.”
A Clear Economic Tradeoff
The measles vaccine is provided free of charge in the United States.
Public health experts emphasize that vaccination not only saves lives — it saves money. As outbreaks grow larger and more frequent, the financial strain on families, employers and health systems is expected to intensify.
The measurable economic burden may already be steep. The true cost — in lost childhoods, long hospital nights and preventable deaths — is far greater.
