The measles outbreaks in the United States have been accelerating, with more than 1,900 people, mostly children, falling ill with the disease in 2025. South Carolina has been particularly hard hit, with at least 111 cases reported and hundreds of people in quarantine. The majority of those affected were not vaccinated against measles, highlighting the importance of vaccination in preventing the spread of infectious diseases.
The increasing number of measles cases is pushing the country closer to losing its measles-free status, a milestone achieved more than 25 years ago. The Centers for Disease Control and Prevention have linked most of the cases this year to 47 outbreaks, a stark contrast to the 16 outbreaks and 285 cases reported in 2024. Tragically, two children have already died as a result of the current outbreaks.
The decline in vaccination rates across communities in the U.S. is a major contributing factor to the resurgence of measles. The measles vaccine, typically administered as part of the MMR (measles, mumps, and rubella) shot, is highly effective in preventing the disease. The U.S. had successfully eliminated measles in 2000 due to widespread vaccination efforts.
Despite the requirement for children to be vaccinated against measles to attend public school, many states allow exemptions for religious or personal reasons. In South Carolina, vaccination rates have dropped from nearly 96 percent in 2020 to 93.5 percent in 2025, falling below the threshold needed for herd immunity. This decline has been fueled by misinformation spread by figures such as Secretary of Health and Human Services Robert F. Kennedy, Jr., and President Donald Trump, who have baselessly linked the MMR vaccine to autism.
It is crucial for communities to prioritize vaccination to prevent the spread of preventable diseases like measles. By supporting science-based journalism, we can help educate the public on the importance of vaccination and combat misinformation that puts public health at risk. Let’s work together to ensure a healthier and safer future for all.
