In 2026, the U.S. faces a resurgence of measles outbreaks, highlighting the critical importance of vaccination amid growing vaccine skepticism and changing public health guidelines.
In 2026, the United States has experienced a significant increase in outbreaks of measles, a highly contagious yet vaccine-preventable disease. In just two months, over 1,136 cases have been reported across 28 states, a stark contrast to the 2,281 cases documented in 45 states in 2025, according to the Centers for Disease Control and Prevention (CDC). Alarmingly, more than 90% of those infected this year were either unvaccinated or had an unknown vaccination status. Among these cases, 24% were children under the age of five, while 57% were between the ages of five and nineteen. It is noteworthy that measles was declared eliminated in the U.S. in 2000.
To address this outbreak, Jay Bhattacharya, director of the National Institutes of Health (NIH) and acting director of the CDC, has urged families to vaccinate against measles. The CDC states that two doses of the measles vaccine are 97% effective in preventing the disease’s spread.
The recent resurgence of measles coincides with a growing skepticism surrounding vaccines. A 2025 poll conducted by the KFF and the Washington Post revealed that 16% of respondents had skipped or delayed a recommended vaccine, while 35% of parents expressed concerns that vaccines do not undergo sufficient safety testing before being recommended for children. Additionally, 26% of parents felt that the CDC recommends too many childhood vaccines.
Vaccination rates for the MMR (measles, mumps, and rubella) vaccine among U.S. kindergartners have declined from 95.2% during the 2019-2020 school year to 92.5% in the 2024-2025 school year. At a recent media briefing on CDC vaccine guidelines, Dr. Richard Besser, a pediatrician and CEO of the Robert Wood Johnson Foundation, attributed current vaccine hesitancy to a lack of trust in public health that emerged during the COVID-19 pandemic.
“People’s trust in vaccination is now damaged in ways that we’re seeing play out around the country,” he stated. “Viruses don’t respect the borders of states. If you are not vaccinated, measles will find you, and measles will infect you.”
The implications of vaccine mistrust on public health are particularly concerning, especially given the differing vaccine recommendations from the CDC and other reputable public health organizations like the American Academy of Pediatrics (AAP). The new CDC schedule has reduced routine recommendations from 17 diseases to 11, moving vaccines such as flu, RSV, hepatitis A and B, rotavirus, and some meningococcal vaccines into “shared clinical decision-making” categories.
The AAP has criticized the new CDC guidelines as “dangerous and unnecessary,” stating that it will continue to follow its immunization schedule, which is supported by over 200 health organizations. Dr. Manisha Panchal, a pediatrician from the San Francisco Bay Area, emphasized the importance of vaccines in reducing the burden of infectious diseases. “When we look at the science behind every individual vaccine, you can see that we’ve come a long way in terms of infectious diseases, largely because of vaccines,” she remarked.
Conversely, Dr. Kirk Milhoan, a pediatric cardiologist and chair of the newly formed Advisory Committee on Immunization Practices (ACIP), has indicated a preference for prioritizing patient autonomy over vaccine mandates. He has suggested a reevaluation of the oral polio and MMR vaccine mandates in the United States, advocating for decisions to be made collaboratively between patients and healthcare providers.
The ACIP, whose recommendations may influence CDC policy, is scheduled to meet on March 18. Concerns about the potential weakening of herd immunity arise from the possibility that the CDC may move away from mandating certain childhood vaccines for school admissions. Dr. Besser expressed alarm, stating, “If you’re sending your vaccinated child to kindergarten, they might be sitting next to a child who is unvaccinated, which could potentially give them something quite serious.”
Dr. Besser also voiced concern over Dr. Milhoan’s comments regarding the review of vaccine mandates, drawing from his experiences visiting a polio hospital in India. “I saw the outcome of what happens in communities that have not had the same access to vaccination, and it’s debilitating,” he said. He cautioned that parents who have never witnessed the effects of polio may struggle to understand the necessity of vaccination against it.
Dr. Panchal echoed these sentiments, noting that communities that have experienced the burden of infectious diseases are often more aware of the consequences of not being vaccinated. She highlighted that the South Asian community in the Bay Area tends to be very pro-vaccine, attributing this to cultural factors and a history of witnessing the impact of disease.
Dr. Besser emphasized the need for public health leaders and trusted local voices to collaborate with communities to provide vaccines in familiar settings such as churches and community centers. He criticized the U.S. decision to withdraw from the World Health Organization, warning that it could jeopardize both American and global health. “Infectious diseases do not respect borders,” he stated, noting that many emerging pathogens arise in areas where humans, animals, and the environment intersect.
In response to the revised CDC vaccine schedule, several states have taken steps to uphold their vaccination guidelines. At least 27 states and Washington, D.C., have rejected some or all of the new CDC recommendations, with many opting to follow AAP guidelines. In late 2025, California enacted legislation to maintain its vaccination schedule, placing the California Department of Public Health in charge of any future changes.
For families uncertain about vaccine decisions, Dr. Panchal encourages open discussions with healthcare providers rather than relying on informal advice from friends. “Doctors are very well versed in understanding the research and the data, and can help you interpret it,” she advised.
As the U.S. grapples with the resurgence of measles and the complexities of vaccine hesitancy, the importance of informed decision-making and community engagement remains paramount in safeguarding public health.
