A 40-year-old woman in Jefferson County, Pennsylvania has died of complications from measles, according to the county's coroner.
It marks the third vaccine-preventable, measles-linked death in the US this year. All three have occurred in Pennsylvania, which is experiencing an explosive outbreak that has caused over 670 cases and 124 hospitalizations across 37 counties. Prior to these deaths, Pennsylvania had not reported a measles death in 35 years.
In a news release dated September 12, Jefferson County Coroner Greg Furlong said the death in the woman was "a heartbreaking loss for the family and an unfortunate reminder that measles can be a serious and potentially life-threatening disease."
The Centers for Disease Control and Prevention is still secretly counting two measles deaths that were deleted from the agency's public measles dataβa deletion that occurred at the direct request of anti-vaccine Health Secretary Robert F. Kennedy Jr., according to two reports released today.
Early today, Reuters reported that Kennedy instructed new CDC director Erica Schwartz to delete the two deaths from the agency's website. CDC staff had reportedly already reviewed information about the deaths and accepted the characterization that they were measles-related. Still, Schwartz deleted the deaths without objection, insiders told Reuters. According to previous reporting, the two deaths were added and then removed from the CDC's website within hours on August 30.
Having more than 150 non-human primates at a research center fall ill with diarrhea in a stomach-churning outbreak that flowed for over two years doesn't sound much like good fortune. But for some scientists, it kind of was, providing a heaping pile of valuable data on how they might finally defeat a foul foe.
In a study published in the latest issue of Science Translational Medicine, scientist sifted through the dump of immunological data from the infections, logging new ways to train immune cells to defeat the bacteria behind the outbreak, a type of Shigella. Researchers were able to pluck out specific bits of the bacteria that the immune system could most effectively attack, linking specific target molecules to specific types of germ-busting immune responses. The researchers even precisely homed in on some of the tiny notches within those craggy target molecules where the most potent antibodies attached.
In all, the study "revealed unexpected features of the anti-Shigella antibody response in naturally infected [non-human primates] and represents a step toward the rational design of Shigella vaccine candidates," the authors write.
The Centers for Disease Control and Prevention is excluding two measles deaths reported by Pennsylvania health officials last week from its latest update of national measles data. The move publicly challenges the accuracy of the state's death determinations in an extraordinary move that breaks precedent that states are the arbiters of case and death determinations, not the CDC.
The New York Times reported Monday that the CDC's new director, Erica Schwartz, is behind the decision. Schwartzβless than a month into the jobβreportedly ordered CDC staff to add an unusual statement onto the CDC's website for measles surveillance data. The statement notes that the update will not include the deaths reported by Pennsylvania and continues: "At this time, available information does not establish whether measles caused or contributed to the deaths or whether the individuals died from other causes while infected with measles."
The Washington Post reported Monday that the CDC had actually changed the information provided on that page multiple times over the weekend. On August 29 at 2:33 pm ET, the website listed the total measles deaths for 2026 as "0" in a chart. On August 30 at 12:09 pm ET, the chart was updated to list the total deaths for 2026 as "2." There was also a note underneath the chart that read: "Health departments make determinations about measles-associated deaths and share relevant information with CDC." By 3:23 pm ET on August 30, the chart was changed again to delete the two deaths, replacing them with an asterisk as a reference to the unusual statement about the deaths not being included. The asterisk and statement remain as of Tuesday.
Senators are renewing calls for anti-vaccine Health Secretary Robert F. Kennedy to step down or be oustedβand at least one is calling for a criminal investigationβamid the release of documents they say prove Kennedy lied to them during his confirmation hearings last year.
"This is a pattern, not a slip," Sen. Edward J. Markey (D-Mass.) said in a statement. "RFK Jr. has lied to the Senate, lied to the American people, and jeopardized the health of children to advance his anti-vaccine agenda."
Sen. Ron Wyden (D-Ore.) said in a social media post Friday that the documents were "Proof we got RFK lying on the record during his confirmation hearing (a crime)." He called for the matter to be referred to the US Department of Justice for a criminal investigation. In a separate statement to The Guardian, Wyden added that "RFK's platform is built on lies and grifts that leave a trail of dead children in their wake. There are consequences for lying to Congress."
In the wake of news on Tuesday that two people in Pennsylvania died from measles, Health Secretary Robert F. Kennedy Jr. has been posting a slew of anti-vaccine rhetoric and misinformation on social mediaβmarking a resurgence of his old ways as a fervent opponent of lifesaving immunizations.
The deaths are the first measles-linked fatalities in Pennsylvania in 35 years and are the first US Β measles deaths reported in 2026. They occurred amid an explosive outbreak in the state that has reached nearly 400 confirmed cases, as well as an ongoing nationwide surge for the vaccine-preventable disease. The US has tallied nearly 2,800 cases so far this year, the highest total since 1991.
Pennsylvania health officials initially declined to provide details about the deaths, only reporting that they were in unvaccinated people from Lancaster County. However, news broke Wednesday that one of the deaths occurred in a newborn baby. That heart-wrenching news was swiftly entangled in the anti-vaccine misinformation Kennedy was spewing online.
Citing privacy, health officials in Pennsylvania are not providing information on the people who died beyond that they were unvaccinated and were residents of Lancaster County. Officials noted that the deaths are among 393 confirmed cases reported this year across 28 counties in the state.
Under anti-vaccine Health Secretary Robert F. Kennedy Jr., the US health department is considering changing how vaccine recommendations are categorized and described. The move creates the possibility that vaccinations currently considered "routine" or "universal" could be given new designations that sound less definitive or more conditional, such as "recommended with qualification" or recommended based on "shared clinical decision-making."
Kennedy has made no new rules or recommendations for the categories yet. However, he laid out ideas and possibilities in a Request for Information (RFI) posted online Friday and published in the Federal Register on Monday. In the 10-page document, Kennedy poses questions about the current categories and asks the public to weigh in on ideas for how to change or replace them. The deadline to comment on the questions and ideas is September 20.
Currently, there are three categories of vaccination recommendations granted by the Centers for Disease Control and Prevention, which is informed by a panel of independent expert advisors, the Advisory Committee on Immunization Practices (ACIP). The three categories are: routine, otherwise considered universal (a recommendation that everyone should get a vaccine); risk-based recommendations (only certain groups at higher risk should get a vaccine); and recommendations based on "shared clinical decision-making," or SCDM (a flexible but uncommon recommendation for vaccination based on the characteristics, values, and preferences of a patient and the judgment of their healthcare provider).
