'Absurd Yet Predictable': US Close to Losing Measles Elimination Status Under RFK Jr.
"The CDC is now completely compromised after Trump and RFK Jr. ousted or drove out real, well-intentioned, and intelligent scientists," said one physician.
US public health officials warned this week that the country is close to following Canada in losing its measles elimination status, a deadly and preventable setback many experts attribute to the vaccine-averse policies and practices of Health and Human Services Secretary Robert F. Kennedy Jr.
Centers for Disease Control and Prevention (CDC) officials have linked the ongoing measles outbreak in Arizona and Utah with the major outbreak in Texas that began in January, both of which are being caused by the same viral subtype. With no signs of slowing, and holiday travel and gatherings fast approaching, experts worry that measles transmission could escalate and the disease will no longer be considered eliminated.
Under World Health Organization guidance, "eliminated" means an absence of endemic virus transmission for 12 months or longer in a defined geographical area under a well-performing surveillance system.
Many public health experts blame the administration of President Donald Trump—and particularly Kennedy's policies—for the measles resurgence. Kennedy, who initially downplayed the seriousness of the Texas outbreak, has endorsed vaccines, but has also made unsupported or misleading claims about the safety and efficacy of measles shots.
"Absurd yet predictable," Dr. Michael O'Brien, an urgent care pediatrician, wrote Thursday on X. "The CDC is now completely compromised after Trump and RFK Jr. ousted or drove out real, well-intentioned, and intelligent scientists. As measles approaches endemic status in the US for the first time since 2000, the CDC has abandoned science and reason."
The anti-vaccination movement is largely to blame for the continuing measles outbreak and the fact that the U.S. is going to lose our measles elimination status. Until RFK Jr. is removed from office, things are only going to get worse. @jimalwine.bsky.social and I wrote about here:

The United States declared measles eliminated in 2000. However, with 1,753 confirmed cases and three deaths in 45 reported outbreaks so far this year, experts say the US is at risk of following Canada, which announced earlier this month that it has lost its elimination status, which it enjoyed since 1998.
As in the US, experts attribute Canada's measles backsliding to declining vaccination rates, mis- and disinformation, and vaccine aversion—especially among religious groups. The West Texas outbreak began in the close-knit, unvaccinated Mennonite community in Gaines County, while the Arizona/Utah outbreak originated among members of a fundamentalist Mormon offshoot.
More than 9 in 10 reported US measles cases this year are among people who have either not been vaccinated or whose vaccination status is unknown.
"We are in this dire situation primarily due to the explosion of the anti-vaccine movement since the start of the Covid-19 pandemic."
Writing for LiveScience, University of Pennsylvania molecular virologist James Alwine and University of Arizona professor emerita and epidemiologist Elizabeth Jacobs warned Wednesday that measles is "a bellwether of declining vaccination rates—a wailing siren that other vaccine-preventable disease outbreaks are just around the corner."
"We are in this dire situation primarily due to the explosion of the anti-vaccine movement since the start of the Covid-19 pandemic," Alwine and Jacobs asserted. "The movement is responsible for undermining trust in scientists and vaccines via a tsunami of misinformation coming from social media accounts and podcast appearances."
The authors continued:
This was made worse when Senate Republicans confirmed Kennedy as secretary of HHS, despite the objections of tens of thousands of scientists, healthcare providers, and public health practitioners. Kennedy is an avowed anti-vaccination proponent who chaired Children's Health Defense, an organization that regularly promotes vaccine misinformation. He is also a conspiracy theorist and has claimed that Covid-19 is a "bioweapon" engineered to "attack Caucasians and Black people" while sparing Ashkenazi Jews; that WiFi causes brain cancer; and that drug use, not HIV, causes AIDS. His appointment opened the door to install anti-vaccine proponents as leaders in public health, such as replacing the members of the Advisory Committee on Immunization Practices (ACIP) with several individuals with links to the anti-vaccine movement. In confirming Kennedy, Senate Republicans utterly failed the people of the US and demonstrated a cavalier disregard for decades of scientific achievement.
In June, Sen. Bernie Sanders (I-Vt.) launched an investigation into Kennedy's ACIP purge. The following month, six major US medical organizations sued Kennedy, alleging his vaccine policies are placing children at grave and immediate risk.
"As the anti-vaccine movement continues to be nurtured by Kennedy and his followers, this threat will only continue to expand and grow more severe," Alwine and Jacobs warned. "Removing state vaccine requirements for school entry—as has happened in Florida—is demonstrative of this, and represents an unacceptable risk."
"Kennedy must be removed from office," they added, echoing a September demand by more than 1,000 current and former HHS officials. "There can be no improvements in public health or vaccination rates as long as he continues his destructive reign."
In September, Congresswoman Haley Stevens (D-Mich.) filed articles of impeachment against Kennedy, declaring that he "has violated his oath of office and proven himself unfit to serve the American people."
Advocacy groups and medical organizations have gathered more than 150,000 petition signatures calling for Kennedy's removal.
On Friday, Congresswoman Kim Schrier (D-Wash.), who chairs the Democratic Doctors Caucus, led 65 colleagues demanding that Kennedy "immediately correct" the CDC website "after it was updated to promote the widely disproven and dangerous claim that vaccines may cause autism."
"RFK Jr.’s decision to spread fringe conspiracy theories and misinformation on the CDC’s official website is reckless," Schrier said in a statement. "He’s scaring parents, undermining trust in the CDC, and putting children at risk.”
