The U.S. is experiencing a severe measles outbreak with over 631 cases reported in multiple states, marking one of the worst surges in decades. Amidst this crisis, Health and Human Services Secretary Robert F. Kennedy Jr. has endorsed the MMR vaccine, asserting it as the most effective means to curb the outbreak. This shift has sparked outrage among his anti-vaccine followers, who feel betrayed by his official stance. Experts highlight the necessity of vaccinations, noting that the outbreak has already resulted in child fatalities. Concurrently, federal funding cuts are complicating public health efforts to address the situation.
