Flu vaccine requirement discarded ‘effective immediately,’ Hegseth says; Military Times, April 21, 2026

 Patricia Kime, Military Times ; Flu vaccine requirement discarded ‘effective immediately,’ Hegseth says

"The U.S. military will no longer require service members to get an annual flu shot according to a post Tuesday by Defense Secretary Pete Hegseth on the social media platform X. 

Hegseth said the mandatory flu vaccine requirement has been discarded “effective immediately.”

“The War Department is once again restoring freedom to our Joint Force,” the secretary wrote. 

The flu vaccine has been required annually for U.S. military personnel since the 1950s to preserve the health of the force, and generally, the Defense Department has aimed to inoculate more than 90% of active-duty personnel. 

The program has been a major factor in lower rates of hospitalizations among service members than national U.S. rates, according to an October 2025 Armed Forces Health Surveillance Division report."

CDC in turmoil after agency backpedals on debunking vaccines-autism link; The Washington Post, November 20, 2025

 Lena H. Sun,  The Washington Post ; CDC in turmoil after agency backpedals on debunking vaccines-autism link

"The Centers for Disease Control and Prevention has repudiated its past insistence that vaccines do not cause autism after decades of fighting misinformation linking the two, blindsiding career staff and delighting anti-vaccine activists.

The agency’s website on vaccines and autism, updated Wednesday, now makes several false claims about a connection, echoing longtime rhetoric from Health Secretary Robert F. Kennedy Jr., who has a lengthy history of disparaging vaccines and linking them to autism.

Career scientists at the agency responsible for information about vaccine safety and autism had no prior knowledge about the changes to the website and were not consulted, according to five agency officials, who spoke on the condition of anonymity for fear of retaliation."

CDC changes website to promote debunked vaccines-autism link; Axios, November 20, 2025

 Maya Goldman , Axios; CDC changes website to promote debunked vaccines-autism link

"The Centers for Disease Control and Prevention has updated its website to promote the widely debunked claim that vaccines may cause autism. 

Why it matters: Health Secretary Robert F. Kennedy Jr. has repeatedly linked vaccines to autism, and now the public health agency he oversees is publicly reversing its position to reflect that belief. 

Multiple studies over decades have disproven links between childhood vaccines and developing autism. 

State of play: The agency's webpage on vaccines and autism, updated Wednesday, now says the statement that vaccines don't cause autism "is not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism."

"Studies supporting a link have been ignored by health authorities," the website continues. 

HHS in September released plans to contract with Rensselaer Polytechnic Institute to research connections between vaccines and autism. 

Career scientists at the agency were not consulted about the changes and were caught off guard by them, the Washington Post reported.

The CDC site previously said studies showed there was no connection between receiving vaccines and developing autism."

How RFK Jr. Mastered Fake Science—and Screwed Us in the Process; The Bulwark, August 10, 2025

 JONATHAN COHN , The Bulwark; How RFK Jr. Mastered Fake Science—and Screwed Us in the Process

"The year is 2035 and the world is dealing with another pandemic, only this time it’s even worse. A bird flu strain has made the leap that scientists have long feared, evolving into a virus that spreads as quickly as COVID-19 but kills at a much higher rate. Businesses and schools have shut down. Economies have crashed. The infected are overwhelming hospitals.

In a virtual press conference, officials announce that there is hope, because the same kind of vaccine that got us through COVID will work this time as well. The catch is that it will take a few more months to develop and produce. And the death toll, already in the millions for the United States alone, is rising fast.

A reporter on the zoom call asks: Why will it take so long? Well, the officials explain, we had a chance about a decade ago to prepare for this by creating a ready-to-deploy vaccine platform that would have shaved months from the process. But our predecessors who were in charge back then killed the funding. So we don’t have that head start.

EVERYTHING ABOUT THE ABOVE SCENARIO is hypothetical—except the final part about the funding. That part happened last week.

On Tuesday, Health and Human Services Secretary Robert F. Kennedy Jr. announced that the Trump administration was canceling about half a billion dollars of federal contracts with companies and institutions that have been working to develop the next generation of mRNA vaccines.

MRNA stands for messenger RNA, the naturally occurring genetic material that cells use as their guide for making proteins. Vaccines with mRNA have a synthetic version of the material, with “coding” instructing cells to manufacture proteins that are part of viruses or other hostile elements, so that the body’s immune system can learn to recognize and fight them."

 MELISSA GOLDIN , AP; FACT FOCUS: RFK Jr.'s reasons for cutting mRNA vaccine not supported by evidence

"Although mRNA vaccines saved millions of lives during the COVID-19 pandemic, U.S. Health Secretary Robert F. Kennedy Jr. incorrectly argued they are ineffective to justify the Department of Health and Human Service’s recent decision to cancel $500 millionin government-funded research projects to develop new vaccines using the technology.

The longtime vaccine critic said in an X video posted Tuesday evening that mRNA vaccines do not adequately prevent upper respiratory infections such as COVID-19 and the flu, advocating instead for the development vaccines that use other processes.

COVID-19 is the only virus for which real-world data on mRNA vaccine effectiveness is currently available, as mRNA vaccines for other diseases, including the flu, are still under development. The two scientists whose discoveries enabled the creation of mRNA vaccines against COVID-19 won a Nobel Prize in 2023 for their work."

Kennedy has caused irreparable harm to vaccines; The Washington Post, June 13, 2025

 Leana S. Wen, The Washington Post ; Kennedy has caused irreparable harm to vaccines

"Robert F. Kennedy Jr. this week put to rest any doubt about his intent to use his perch as health and human services secretary to advance his long-standing anti-vaccine agenda. In an unprecedented move, Kennedy fired all 17 members of the Centers for Disease Control and Prevention’s key vaccine advisory committee. He has since named eightreplacements, at least two of whom are outspoken vaccine skeptics.

One of them is Robert Malone, who became known during the pandemic as a prominent critic of coronavirus vaccines, suggesting, among other falsehoods, that they cause a form of AIDS. More recently, he claimedthat a Texas child who died of measles had not actually succumbed to the disease. Another pick is Vicky Pebsworth, who blames vaccines for causing her son’s autism. She has praised discredited former physician Andrew Wakefield, whose fraudulent research falsely linked vaccines to autism, and represented organizations that question vaccine safety.

Less is known about some of the other committee members’ vaccine views or, with the exception of infectious-disease specialist Cody Meissner, what makes them qualified to advise the CDC on vaccine recommendations. No matter what the newly restructured panel — known as the Advisory Committee on Immunization Practices, or ACIP — decides, Kennedy will have already achieved his goal of causing irreparable harm to the CDC and eroding the public’s trust in vaccines."

RFK Jr. Conducts His Vaccine Purge: His claims about conflicts of interest proved to be nothing.; Wall Street Journal, June 10, 2025

 The Editorial Board , Wall Street Journal; RFK Jr. Conducts His Vaccine Purge: His claims about conflicts of interest proved to be nothing.

"We’d like to conclude we were wrong to oppose Robert F. Kennedy Jr. to run the Health and Human Services Department, but alas, no. The latest evidence is his purge of a vaccine advisory panel."

RFK Jr. Is as Bad as We All Imagined: If it walks like a quack, talks like a quack, and quacks like a quack.; The Bulwark, June 10, 2025

, The Bulwark; RFK Jr. Is as Bad as We All Imagined: If it walks like a quack, talks like a quack, and quacks like a quack.

"In an op-ed in the Wall Street Journal, Kennedy launched his latest offensive against America’s vaccines, announcing he had fired all seventeen members of the Centers for Disease Control’s Advisory Committee for Immunization Practices (ACIP). Kennedy, a dyed-in-the-wool anti-vax activist, said in an accompanying statement that the move had been necessary to “reestablish public confidence in vaccine science” and to rid the committee of “any specific pro- or anti-vaccine agenda.” He said he would appoint replacements, presumably before the ACIP’s next meeting, which is scheduled to begin in two weeks.

The ACIP’s influence on federal health policy is enormous. As the CDC’s institutional brain trust for best-in-class vaccine science, it issues guidance that shapes federal policy for recommended vaccine schedules, including which vaccines should be administered to children. (Notwithstanding Kennedy’s odd assertion that the committee had “never recommended against a vaccine,” the ACIP does not authorize new vaccines for public use, a responsibility that belongs to the Food and Drug Administration.)

How important is the ACIP? Important enough that Sen. Bill Cassidy, a Republican and a doctor, made it his line in the sand for supporting Kennedy’s nomination as secretary of health and human services—a nomination he could have derailed. In announcing his decision to vote yes on Kennedy, Cassidy said the nominee had committed to him that he would maintain the ACIP “without changes.”

In response to yesterday’s news, Cassidy blandly noted “the fear that the ACIP will be filled up with people who know nothing about vaccines except suspicion” and lamely promised to “continue to talk with [Kennedy] to ensure this is not the case.”

RFK Jr. fires CDC’s independent vaccine advisors; The Hill, June 9, 2025

NATHANIEL WEIXEL , The Hill; RFK Jr. fires CDC’s independent vaccine advisors

"Health and Human Services Secretary Robert F. Kennedy Jr. said he is removing every member of the independent panel advising the Centers for Disease Control and Prevention on vaccines, an unprecedented escalation in his quest to reshape the agency.

In a Wall Street Journal op-ed released Monday, Kennedy said the move was necessary to restore faith in vaccines. 

“A clean sweep is needed to re-establish public confidence in vaccine science,” Kennedy wrote. 

“The public must know that unbiased science—evaluated through a transparent process and insulated from conflicts of interest—guides the recommendations of our health agencies,” Kennedy said in a subsequent statement. 

Kennedy said removing every member of the panel will give the Trump administration an opportunity to appoint its own members. Kennedy has long accused ACIP members of having conflicts of interest, sparking concern among vaccine advocates that he would seek to install members who are far more skeptical of approving new vaccines."
