Measles Outbreak in South Carolina Reaches Record High, Sparking Concerns Over Vaccine Confidence.
South Carolina has witnessed a staggering 789 measles cases since the outbreak began last October, surpassing the number of cases from the Texas outbreak in 2025. The state's upstate region, particularly Spartanburg County, has been at the epicenter of this alarming trend. With the United States declared to be free of locally transmitted measles infections over a decade ago, this outbreak is a stark reminder that the country still faces significant challenges.
The Centers for Disease Control and Prevention (CDC) has reported that there have been no new outbreaks across the country in 2026, but experts caution that the recent surge in cases may indicate a pattern of reduced vaccination rates. Of the 789 cases, nearly 70 percent were reported as unvaccinated or unknown, with children aged 0 to 11 being disproportionately affected.
The measles, mumps, and rubella (MMR) vaccine is crucial in preventing outbreaks like this one. The CDC recommends administering two doses of the MMR vaccine starting at 12 months of age, but concerns over vaccination confidence have been raised by comments from HHS Secretary Robert F. Kennedy Jr. Kennedy's statements have been interpreted as undermining the safety and efficacy of vaccines.
Despite Kennedy's claims that vaccines can cause adverse events, including deaths and illnesses like encephalitis and blindness, health experts emphasize that these risks are extremely rare in healthy individuals. The Infectious Diseases Society of America notes that there have been no reported deaths related to the MMR vaccine in people without compromised immune systems.
William Moss, executive director of the International Vaccine Access Center, has expressed concern over the ongoing outbreak and its potential implications for measles elimination status. "Maintaining adequate levels of measles vaccination is crucial to preventing future outbreaks," he says. "As vaccine confidence continues to be undermined, immunization becomes more important than ever."
