In a concerning development, two unvaccinated residents of Lancaster County, Pennsylvania have died due to measles, marking the first fatal cases this year in the United States. The Pennsylvania Department of Health reported the deaths on Tuesday, emphasizing privacy concerns as reasons for withholding additional details. Pennsylvania Secretary of Health Debra Bogen expressed concern that, because measles had been largely eliminated in the state for over three decades, people might be unfamiliar with the disease and underestimate its potential severity. The US is currently grappling with one of its most severe measles outbreaks in years, as vaccination rates have dropped below levels recommended by medical experts to achieve herd immunity. This decrease has been partly attributed to an anti-vaccination movement, which includes high-profile members of the Trump administration such as Health and Human Services Secretary Robert F Kennedy Jr. As of now, at least 2,777 confirmed cases of measles have been recorded in the US this year, with Pennsylvania among the states hardest hit by the outbreak. On March 2nd, US President Donald Trump signed an executive order calling for a reduction in the number of recommended vaccines for children, continuing efforts to roll back decades of scientific consensus on the safety and efficacy of vaccinations. Trump and Kennedy have faced criticism for promoting debunked claims linking vaccinations with autism and dismantling government health panels tasked with making recommendations on vaccine policy. Dr Angela Dunn, a former Utah state epidemiologist, expressed concern that the measles outbreaks in Texas last year and in South Carolina and Utah this year would serve as wake-up calls for the public, yet the issue persists. In 2025, three people died from a measles outbreak that originated in West Texas and spread to New Mexico.
