How right-wing media sow distrust and confusion around vaccines and science

As Florida ends school vaccine requirements and Robert F. Kennedy Jr.’s leadership comes under fire, the right has repackaged anti-science talking points as well-meaning skepticism

Amid the rise of the so-called “Make America Healthy Again” movement, right-wing media figures have employed a variety of tactics that sow doubt and confusion around vaccine efficacy and science more broadly. These efforts to capitalize on existing distrust of public health institutions and pharmaceutical companies have gained renewed momentum following Florida’s elimination of vaccine requirements for schools and comments made by Health and Human Services Secretary Robert F. Kennedy Jr. during a contentious Senate hearing.

MAHA acolytes have challenged well-studied topics by “just asking questions,” described vaccination requirements as impediments to freedom and parental choice, and exploited post-pandemic mistrust of public health infrastructure and pharmaceutical companies. 

  • The MAHA movement is fueling mistrust in medicine amid a CDC leadership shake-up and Florida's elimination of vaccine requirements

    • In early September, Florida Surgeon General Joseph Ladapo announced the state is working to eliminate all vaccine requirements for children in public schools, an announcement which quickly came under fire by doctors and public health experts. In his statement to the public, Ladapo said of vaccines, “Every last one of them is wrong and drips with disdain and slavery.” The American Medical Association released a statement opposing the move, stating: “This unprecedented rollback would undermine decades of public health progress and place children and communities at increased risk for diseases such as measles, mumps, polio, and chickenpox resulting in serious illness, disability, and even death.” [NBC News, 9/3/25; The American Medical Association, 9/3/25
    • After the firing of Centers for Disease Control and Prevention Director Susan Monarez, HHS Secretary Robert F. Kennedy Jr. faced scrutiny from both sides of the aisle at a contentious Senate hearing where many called for his resignation. Monarez’s firing spurred other top CDC officials to step down and caution the public over the state of the organization’s scientific independence. This, along with criticism for canceling $500 million in funding for mRNA research that produced the lifesaving COVID-19 vaccine, contributed to a dramatic hearing where senators sparred with Kennedy. Sen. Bill Cassidy (R-LA), who voted for Kennedy’s confirmation, said the Food and Drug Administration’s recommendation that only people at high risk for complications and those over 65 need the vaccine effectively denies people access to the shot.

    • At a September 17 Senate hearing, Monarez testified that Kennedy had told her “that the ‘childhood vaccine schedule would be changing starting in September’ and that she ‘needed to be on board with it.’” According to NPR, Monarez told the senators that Kennedy “just wanted blanket approval” adding, “Even under pressure, I could not replace evidence with ideology.” [NPR, 9/17/25]
    • The New York Times used AI to analyze 38 MAHA figures and organizations featured in around 12,000 videos and podcasts, concluding that these influencers amplify frustration with the health care system to reel viewers in “using wellness content as a trojan horse for conspiracy theories.” The Times noted that some of these figures are using these platforms to sell a product rather than to meaningfully address public health problems like poverty or lack of access to nutritious food and health care. One interviewee who got pulled down the MAHA rabbit hole said, “I thought if my daughter got vaccinated, she would die in her sleep that night.” [The New York Times, 9/9/25]
  • Tactic 1: “Just asking questions” about established science as a means to sow doubt

  • Right-wing media figures have presented uninformed, speculative questions about the safety of vaccines as legitimate criticism of the science, saying there’s nothing wrong with “wanting to ask questions” and often presenting their own queries as evidence that established bodies of research should be approached skeptically. In an essay for Big Think, Warren Berger argued that people falsely equate “questioning with critical thinking” and added that conspiracy theorists “act as if their uninformed, speculative questions demand that someone else provide answers.” Kelly Weirich, professor of philosophy at Pierce College, also stated that “while questions technically don’t make claims, they do affirm claims in a subtler way through the assumptions embedded in them.” University of Dayton lecturer Megan Donelson noted that the right’s tactic of “just asking questions” in this way “serves to undermine public trust in science and medicine.” 

    • Fox & Friends co-host Lawrence Jones attacked Democrats questioning Kennedy, saying, “I guess the most frustrating thing about the entire hearing is there seems to be zero curiosity on why we're such a sick nation.” Jones continued, “I do have some genuine curiosity about the science about each vaccine. And it didn't seem like they were trying to get to the bottom of that or even hear him out.” [Fox News, Fox & Friends9/5/25]
    • Fox & Friends co-host Brian Kilmeade asked, “When do you give the vaccines? Are you giving them all at once? Does that play into autism?” He claimed that in a few weeks, Kennedy “will announce the cause of autism, or the likely cause, which I think is extremely beneficial for us.” [Fox News, Fox & Friends9/5/25]
    • Jones later said that “there is something wrong with some of the vaccines,” adding that “not all of them are bad, but there are questions that Americans have about it.” He continued, “They should be able to give us answers. But we're not conducting our own studies. We depend on foreign people to do the studies, and there’s questions there.” [Fox News, Fox & Friends9/8/25]
    • On The Five, co-host Lisa Kennedy Montgomery claimed, “I disagree with him [Kennedy] on a lot of stuff but at least he makes me think about vaccines.” She added, “I think that is the best thing we can do as a society. And have these honest discussions about how we look and what we are putting in our bodies, and the solutions we are giving our children when we are failing them — when all of these institutions are failing them.” [Fox News, The Five9/4/25]
    • Fox host and former Trump White House press secretary Kayleigh McEnany said she doesn’t agree with everything Kennedy says but likes his “healthy skepticism for the science, wanting to ask questions about your children, what we are putting in their bodies.” [Fox News, The Five9/5/25]
    • Fox News’ Sean Hannity asked MAHA podcaster Gary Brecka, “Are we overprescribing generally as a society and overvaccinating?” Brecka responded, “We are the most over-medicalized nation in the world,” describing the U.S. as “the sickest, fattest, most disease-ridden nation in the world.” [Fox News, Hannity9/4/25]
    • Newsmax host Rob Finnerty asked if it's possible that former President Joe Biden is “vaccine-injured” and suggested vaccination caused his cancer. [Newsmax, Finnerty9/2/25]
    • Fox News host Laura Ingraham noted that “Kennedy and others have raised questions about the number of new vaccines added to the recommended pediatric schedule.” Citing the supposedly “staggering” increase in recommended vaccinations, Ingraham argued that it “makes total sense” to change COVID vaccine approvals. [Fox News, The Ingraham Angle9/4/25]
  • Tactic 2: Presenting vaccine requirements as impediments to freedom and parental choice

  • Criticisms against public health policy surged at the height of the COVID-19 pandemic, and rhetoric equating vaccine mandates to government overreach has persisted within the right-wing media ecosystem. The Nations Health, an outlet of the American Public Health Association, has highlighted several recent examples of the “medical freedom movement” undermining public health by removing fluoride from tap water and promoting alternative medicines. Additionally, the new CDC recommendations will make it more difficult for those who wish to get vaccinated for COVID-19, as the vaccines may no longer be covered by insurance companies. 

    • On his radio show, Fox host Sean Hannity celebrated the Florida mandate rescission, which he claimed was “giving people freedom and giving people choice, which I think is great.” [Premiere Radio Network, The Sean Hannity Show9/4/25]
    • Hannity: “Masks may be coming back to California while the free state of Florida is moving to end draconian vaccine mandates for your children in school.” [Fox News, Hannity9/4/25]
    • Right-wing influencer Benny Johnson wrote that “vaccine mandates are wrong” and “Florida is absolutely right to remove them,” adding, “Parents should have the final say over kids’ health, not the government.” [Twitter/X, 9/4/25]
    • Dr. Simone Gold, an anti-vaccine activist and January 6 participant, celebrated the FDA’s move to end Emergency Use Authorization for the COVID-19 vaccine, stating, “Mandates are dead. Freedom wins.” [Twitter/X, 8/27/25, ABC News, 6/12/22]
    • Fox & Friends co-host Ainsley Earhardt emphasized parental choice while talking about COVID vaccines, saying, “As a mom, I’m going to decide what my child gets.” Earhardt: “There were a handful of us that didn't want our kids to have the COVID vaccine. That was my choice as a mom, because we interviewed so many kids — the kid who played soccer out on Long Island, who fell and had a heart problem, can’t play anymore, and his parents thought it was because of the vaccine. I just heard so many stories like that, I made the decision for myself.” [Fox News, Fox & Friends9/5/25]
  • Tactic 3: Exploiting distrust of public health organizations, experts, and pharmaceutical manufacturers

  • The MAHA movement and Kennedy — who according to NPR’s Selena Simmons-Duffin “seems to assume bad intent among experts” and who has accused public health agencies of “deliberately manipulating the truth” — have seized on a wider sense of mistrust and confusion following the COVID-19 pandemic. According to a report from Politico, “An increasing number of families are projecting their attitudes toward the Covid-19 vaccine onto shots for measles, chickenpox, meningitis and other diseases,” and “parents who were hesitant to vaccinate their children before the pandemic have now been joined by people who think the government mishandled the crisis.” Now, despite evidence suggesting that the COVID-19 vaccine saved millions of lives, Kennedy and his MAHA acolytes are exploiting this distrust in public health institutions to appeal to a base that “felt angered by a lot of early pandemic policies” and “felt betrayed by the government.” 

    • Fox News contributor Dr. Nicole Saphier claimed, “The CDC lost all credibility throughout the COVID pandemic when they continued to universally recommend the COVID vaccine, even after the science changed.” She continued, “The problem here we have is that all of these vaccines are being lumped as though that they are created equally and they have the same benefit, and the reality is that's not true. So while removing all vaccine mandates for school-aged children is swinging that pendulum from one extreme to the other extreme, truly Americans — and especially our children — deserve more of a nuanced discussion about this.” [Fox News, Fox & Friends9/4/25]
    • Right-wing podcaster Liz Wheeler wrote that fewer people now believe the government should “forcibly vaxx kids” because “70+ shots added to the schedule, an insane epidemic of autism, ADHD, cancer, neurological issues, & autoimmune diseases among CHILDREN.” She continued, “A generation of children have been hurt, and we all know it. If you think Bobby Kennedy doesn’t have America’s support, you’re crazy.” [Twitter/X, 9/4/25]
    • Wheeler reposted a video of Kennedy on Fox & Friends claiming the CDC was hiding vaccine safety data from him. She wrote, “I wonder why?” [Twitter/X, 9/7/25]
    • The Daily Wire’s Michael Knowles claimed the CDC “lost their credibility during COVID,” adding, “They lied to us about vaccines.” He continued, “They lied to us about the efficacy of the vaccine. They lied to us about the safety of the vaccine. They lied to us about everything regarding the vaccine.” [The Daily Wire, The Michael Knowles Show9/2/25]
    • Newsmax’s Rob Finnerty claimed, “Hundreds of millions of people were forced to get the vaccine” during the COVID pandemic, adding, “People have had adverse reactions to this vaccine we were told was safe that was forced upon us.” [Newsmax, Finnerty9/4/25]
    • TownHall writer Scott Morefield shared a Truth Social post from President Donald Trump in which he asked pharmaceutical companies to “justify the success of their various Covid Drugs,” adding, “This kind of spotlight on the efficacy of the mRNA jabs could cause the whole house of cards to come crashing down.” Morefield celebrated Trump’s post, stating, “I didn’t think Trump’s ego would ever allow him to do this, but he continues to pleasantly surprise me,” and ending with “Bravo!” [Twitter/X, 9/1/25]
    • Fox News host Jesse Watters questioned the vaccine recommendations for children, saying the “people at the CDC recommending it are at the CDC because the vaccine industry put them there,” and he accused senators of “blindly defending vaccine companies like it's their job.” Watters: “Why does a baby get 18 shots before they are 18 months old? It used to be eight — now it's 18. Why does a kid have 76 shots before they are old enough to vote? We never used to get that many, but the CDC recommends this. And the people at the CDC recommending it are at the CDC because the vaccine industry put them there. Maybe 76 is the right amount. Maybe it could be a little less or a lot less. We don't know. RFK is just trying to get a fresh set of eyes on it and look at the data. And senators are blindly defending vaccine companies like it's their job.” [Fox News, Jesse Watters Primetime9/4/25]
    • Watters suggested that people advocating for vaccinations are doing so to keep getting “pharma cash.” Watters: “If Kennedy isn’t recommending healthy 18-year-olds get COVID boosters, then there's less pharma cash to spread around to the politicians. If a baby gets eight vaccines instead of 18, less cash to spread around to the politicians. If doctors tell patients to eat healthy and exercise instead of get the fat shot, less cash to the politicians. Same thing with sex changes, diabetes medication, and antidepressants. Did you know that the American Academy of Pediatrics, some of their biggest donors — vaccine makers? Take the COVID vaccine. Nothing they said about the COVID vaccine turned out to be true.” [Fox News, Jesse Watters Primetime9/4/25]
    • Newsmax's Rob Schmitt described comments from senators questioning Kennedy as “enraged insults from politicians who have either been bribed to protect Big Pharma or those who have fully drunk their Kool-Aid.” [Newsmax, Rob Schmitt Tonight9/4/25]
