Sen. Bernie Sanders on Tuesday launched an investigation into U.S. Secretary of Health and Human Services Robert F. Kennedy Jr.'s purge of independent experts from a panel on vaccine recommendations.
Last month, Kennedy announced that he was "retiring" all 17 members of the Advisory Committee on Immunization Practices, or ACIP, despite promising during his Senate confirmation hearing to keep the committee intact.
At the time, Sanders (I-VT), chair of the Senate Committee on Health, Education, Labor, and Pensions, warned that "firing independent vaccine experts is a dangerous, unprecedented move that will make it harder for the American people to access vaccines that are safe, effective, and essential to saving lives."
After the firings, Kennedy said, "We're going to bring great people onto the ACIP panel—not anti-vaxxers—bringing people on who are credentialed scientists."
In a letter sent to Kennedy on Tuesday, Sanders and seven other Democratic senators said those fears have come to pass. Kennedy, they said, has replaced the panel of experts with "prominent vaccine deniers."
The most prominent of these figures is Dr. Robert Malone, who has described it as "high praise" to be dubbed an "anti-vaxxer."
Malone gained prominence during the COVID-19 pandemic by casting doubt on the illness's severity and baselessly suggesting that the mRNA vaccines used to treat the disease were "causing a form of AIDS."
Earlier this year, Malone also attempted to foment doubt that children had died due to the unprecedented measles outbreak in Texas.
Kennedy also appointed the former leader of his anti-vaccine organization, the Children's Health Defense, Lyn Redwood, a longtime proponent of the false belief that the vaccination for measles, mumps, and rubella (MMR) causes autism.
Also on the committee is Vicky Pebsworth Debold, founder of the National Vaccine Information Center—one of the longest-running anti-vaccine organizations in America—who has argued that a vaccination caused her child's autism.
ACIP is in charge of examining scientific findings to make recommendations to the public about which vaccines to get and when.
"These individuals," the senators said, "have already taken steps to upend decades of scientific research and vaccine policy, threatening the health and safety of all Americans."
When Kennedy's new handpicked committee met for the first time in late June, the members made substantial changes to vaccine policy and hinted at others coming in the future.
The most significant change they made was the recommendation that Americans receive flu vaccinations free of the preservative thimerosal, which is partially made of mercury and prevents germs and fungi from contaminating batches of vaccines.
Thimerosal, which is a component of many multidose vaccines, has never been found harmful by any scientific study. The Centers for Disease Control and Prevention (CDC) provided a document to the committee that included 25 years of studies indicating thimerosal's safety. But that document was removed from the meeting without explanation.
When they questioned ACIP about its removal, the senators say Malone replied that it was "not authorized by the office of the secretary," which the senators concluded meant that Kennedy or one of his staff "had the document taken off CDC’s website."
Instead of credible science, Redwood presented a report likely generated by artificial intelligence, which included many debunked claims about the dangers of thimerosal, and even made reference to a CDC study on the dangers of the preservative that did not exist.
Kennedy's ACIP also determined that it would revise the childhood vaccine schedule that has been in place for decades. That schedule includes vaccines for polio, chickenpox, diphtheria, and tetanus—illnesses that once routinely killed children but have been virtually eradicated by mass immunization.
The recommended vaccine schedule, the senators noted, determines what immunizations are required to be covered by health insurance companies and government programs like Medicaid and Medicare.
"If insurance companies, Medicare, Medicaid and other government programs stop covering vaccines, Americans will be forced to pay out of pocket," the senators said. "The only people who will be able to afford vaccines will be the wealthy."
The senators warned that this, along with Kennedy and his appointees' undermining of vaccine science, would result in "a resurgence of vaccine-preventable diseases."
Under Kennedy, the United States has already experienced its largest measles outbreak in 33 years, which has resulted in the first deaths from the disease in over a decade, following a downswing in measles vaccination.
Despite this, Kennedy has continued to downplay the disease's severity and the vaccine's well-documented effectiveness, even claiming that it causes "deaths every year."
The senators demanded that Kennedy provide information about why each of the nonpartisan members of ACIP were fired, and what criteria and vetting process was used to pick the anti-vaccine figures who replaced them.
"The harm your actions will cause is significant," the senators told Kennedy. "As your new ACIP makes recommendations based on pseudoscience, fewer and fewer Americans will have access to fewer and fewer vaccines. And as you give a platform to conspiracy theorists, and even promote their theories yourself, Americans will continue to lose confidence in whatever vaccines are still available."
