RFK Jr urges measles vaccination amid record US outbreaks, sparking controversy
Consensus Summary
US Health Secretary Robert F Kennedy Jr urged parents to vaccinate children against measles in a CNN interview, marking a shift from his long-standing vaccine skepticism. The US is facing its worst measles outbreak in 35 years, with 2,371 confirmed cases in —surpassing the 2,289 cases recorded in 2025, the highest since 1991. The past two years combined have seen more infections than the rest of the 21st century, threatening the country’s measles elimination status held since 2000. Vaccination rates among kindergarteners dropped to 92.5% in 2024-25, down from 95.2% in 2019-20, fueling outbreaks in states like Utah, Arizona, and South Carolina. Kennedy’s call for vaccination came amid controversy, as he previously spread misinformation about vaccines, including claims about lab manipulation of diseases like RSV and Lyme, and doubts about Covid-19 vaccines. International health officials are set to meet in November to assess whether the US and Mexico have lost their measles-free status, with experts warning reported cases may underestimate the true spread.
