The United States is facing a concerning rise in measles cases, the highest numbers seen since 2000, prompting a call to action from an unlikely source: Dr. Mehmet Oz, administrator of the Centers for Medicare & Medicaid Services. This plea comes as the nation risks losing its status as a measles-eliminated country, a designation increasingly threatened by declining vaccination rates. The situation highlights a complex public health challenge, complicated by ongoing skepticism towards vaccines, even within the current administration.
Dr. Oz, in a recent interview with CNN, urged Americans to get vaccinated against measles, stating simply, “Please, get vaccinated.” He acknowledged that not all diseases pose equal threats, but emphasized the seriousness of measles, a highly contagious and potentially dangerous illness. This message arrives at a critical juncture, as outbreaks are occurring in multiple states, including Carolina del Sur, where cases have surpassed those reported in the 2025 Texas outbreak, and along the Utah-Arizona border. The increasing incidence of measles is raising alarms among public health officials and prompting a reevaluation of vaccination efforts.
A Shift in Tone from the Trump Administration
The call for vaccination from Dr. Oz is particularly noteworthy given the previous stance of the Trump administration, which has often been perceived as skeptical of vaccines. Robert F. Kennedy Jr., the current Secretary of Health and Human Services, has long questioned the safety of vaccines and has been overseeing a review of federal vaccination recommendations, including those for hepatitis B, COVID-19, and the combined measles, mumps, rubella, and varicella vaccine. CNN’s Dana Bash directly questioned Oz about the apparent contradiction between his advocacy for vaccination and Kennedy Jr.’s views, a point that underscores the internal tensions surrounding this issue.
Despite Dr. Oz’s urging, experts believe a sudden shift in vaccination levels is unlikely. Current measles vaccination coverage falls below the 95% threshold needed to maintain herd immunity. In areas experiencing significant outbreaks, such as Texas and Carolina del Sur, vaccination rates are considerably lower. This underscores the challenge of overcoming vaccine hesitancy and reaching vulnerable populations.
“Too Little, Too Late?” Experts Weigh In
Sruti Nadimpalli, an associate clinical professor specializing in pediatric infectious diseases at Stanford University, expressed concern that Dr. Oz’s call for vaccination “comes too late.” She emphasized the need for consistent and proactive support for childhood vaccinations from leaders, citing the well-established safety and efficacy of these vaccines. “We need our leaders to proactively, firmly, and consistently support childhood vaccines, whose safety and efficacy have been repeatedly demonstrated,” Nadimpalli stated in an email.
Data from the Johns Hopkins University Center for Immunization Access shows a significant increase in measles cases in the first five weeks of 2026, with 866 cases reported nationwide, compared to just 71 cases during the same period last year. This surge in cases is a stark reminder of the vulnerability created by declining vaccination rates.
Global Trends: A Mixed Picture
While the U.S. Is experiencing a resurgence of measles, other regions are seeing positive trends. Europe and Central Asia reported a 75% decrease in cases between 2024 and 2025. However, this progress is fragile. In September 2025, 32 European countries were declared measles-free, but by January, several, including Austria, Spain, and the United Kingdom, had lost that status. This demonstrates the ease with which measles can re-emerge when vaccination rates decline.
Both in Europe and Central Asia, and in the United States, health services are grappling with a combination of under-vaccination, loss of herd immunity, and outbreaks in vulnerable communities. A lack of understanding regarding the dangers of highly contagious childhood diseases is exacerbating the problem. Fatima Cengic, a UNICEF immunization specialist for Europe and Central Asia, warned, “Given the global evolution of the situation, we foresee a sizeable problem.” She explained that immunization has turn into a victim of its own success, as the relative rarity of measles due to past vaccination programs has led to complacency and decreased vaccination rates.
Cengic similarly pointed to insufficient funding for immunization programs, noting that governments, having successfully prevented deaths from measles, are often less willing to prioritize and invest in these initiatives. “Due to its great success in preventing deaths, governments are not as willing to pay as much attention to it or invest in immunization programs, so they often lack sufficient funds,” she criticized.
The situation underscores the ongoing need for robust vaccination programs, clear public health messaging, and sustained investment in immunization efforts. The coming months will be critical in determining whether the U.S. Can regain control of measles and maintain its status as a measles-eliminated country. Continued monitoring of vaccination rates and outbreak patterns will be essential, as will efforts to address vaccine hesitancy and ensure equitable access to vaccination services.
