Pennsylvania Conditionally Seeks CDC Help on Measles

Pennsylvania is requesting emergency CDC support for its measles outbreak, but will rescind the request unless the agency recognizes the state's four deaths.

The Pennsylvania health department has begun the process to request emergency CDC assistance, known as an Epi-Aid, as it battles one of the country's largest and deadliest measles outbreaks. According to Reuters, which reviewed a letter sent Wednesday evening by state health secretary Debra Bogen to CDC director Erica Schwartz, the request carries an explicit condition: the CDC must publicly recognize the four measles-associated deaths reported by the state. Bogen wrote that the CDC's choice not to acknowledge the deaths undermines the state's response, and said the department will respectfully rescind the Epi-Aid request if the agency cannot communicate transparently about them. The move escalates an unusual standoff between a state and its own federal health agency over basic outbreak facts.

The request reverses course: Pennsylvania had previously resisted CDC help, arguing it had the outbreak under control, Reuters reports. Health Secretary Robert F. Kennedy Jr. has cast doubt on whether deaths reported in U.S. measles outbreaks since he took office were due to the virus or another cause, and instructed the CDC not to include the Pennsylvania fatalities in the national tally. Disease experts told Reuters this represents highly unusual interference by a health secretary in state health officials' determinations, and could minimize the apparent risk of measles to the public. A state now demanding acknowledgment of deaths as the price of federal aid underscores how contested routine mortality counting has become.

Governor Josh Shapiro and HHS Secretary Kennedy are trading accusations over playing politics with the deadly outbreak, CNN reports in an interview on The Source with Kaitlan Collins. Kennedy has accused Shapiro of politicizing the outbreak in Pennsylvania and of failing to request federal help — a claim undercut by the state's new Epi-Aid request. The Guardian, meanwhile, documents the parallel public-health fight: with the country's top health official questioning vaccine efficacy and undermining vaccine science, the job of reassuring parents has shifted downward to governors, state legislatures, health departments and frontline doctors mounting an urgent campaign to defend childhood vaccines.

The Guardian reports that measles cases in Pennsylvania climbed to 693 as of 14 September, with four residents' lives claimed so far this year. According to Reuters, the outbreak has since grown to more than 700 confirmed cases across 37 counties and four measles-associated deaths, making it part of the worst U.S. measles resurgence in more than three decades, fueled by rising vaccine hesitancy. Local responses are scaling up: The Guardian describes Delaware County's mobile vaccine clinic — a 33-foot traveling RV serving community events — and a Yeadon school-partnership clinic that vaccinated 42 middle and high school students on 'exclusion day' so they could return to class.

The Guardian reports that a recent Trump executive order, the 'gold standard childhood vaccine recommendations,' seeks to cut universally recommended childhood vaccines from 17 to 11 and split the MMR shot into three separate injections, with no new scientific evidence behind it. CDC data shows kindergarteners' vaccine exemptions hit a record high for the 2025-26 school year while vaccination rates fell, per The Guardian. The response is restructuring federalism in health: The Guardian reports 30 states now rely on guidance other than the CDC, such as the American Academy of Pediatrics, and 15 states have sued the administration over its changes to the childhood vaccine schedule. In August, Pennsylvania providers administered more than 46,000 MMR doses versus roughly 31,000 a year earlier.

The immediate question is whether the CDC will accept Pennsylvania's condition. According to Reuters, Bogen wrote that if the agency cannot transparently and accurately communicate information about the measles-associated deaths, the department will rescind its Epi-Aid request — leaving federal support in limbo. CNN's interview with Governor Shapiro signals the political fight will continue in public view, with each side accusing the other of exploiting the outbreak. Meanwhile, The Guardian reports states are building durable workarounds: regional health coalitions, school-level vaccination data publishing, insurance regulation to keep vaccine coverage, and doctors filling an information vacuum by walking parents through basic vaccine safety the federal government no longer reliably communicates.
