An 8-year-old girl recently became the third person to die in a Texas measles outbreak, bringing attention to Robert F. Kennedy Jr., the health secretary, who endorsed the MMR vaccine but also promoted unproven treatments. Experts criticize his framing that suggests equal efficacy between vaccination and alternative treatments, warning it may exacerbate the outbreak, which has now reached 541 cases in Texas alone. As misinformation spreads, the risk of losing the U.S.’s measles-eliminated status increases, with serious implications for public health.
