US Health Officials Quiet Anti-Vaccine Rhetoric Ahead of Midterm Elections
As November's midterm elections approach, US health officials appear to be shying away from voicing negative views about vaccines in public forums. Key polling data indicates that anti-vaccine positions have become a significant political liability, prompting a strategic shift in messaging from prominent figures within the health administration.
Strategic Silence on Vaccines
Health officials have implemented unprecedented changes to routine vaccine recommendations over the past year, including slashing one-third of the US childhood immunization schedule. Notably, the recommendation for hepatitis B vaccination at birth was removed. However, even before a federal judge essentially invalidated these moves, officials stopped championing these dramatic changes. This shift followed advice from Donald Trump's pollsters, who recommended veering away from anti-vaccine ideology ahead of the crucial midterm elections.
The elections seem to be top-of-mind for US health officials across various platforms. At a March conference on women's health sponsored by the US Department of Health and Human Services, FDA Commissioner Marty Makary referenced support from the "Make America Healthy Again" (Maha) movement in the 2024 election, stating that "Moms showed up to vote for the Maha agenda."
Kennedy's Notable Shift in Focus
At the conservative CPAC conference in late March, HHS Secretary Robert F Kennedy Jr—a longtime vaccine opponent—did not explicitly mention immunizations once during his 30-minute "fireside chat" with conference organizer Mercedes Schlapp. When asked what advice he would give to "Maha moms" or "Maha parents," Kennedy avoided his typical two decades of rhetoric about toxic exposures and vaccines. Instead, he identified cell phones and social media as "the biggest threats that we're facing now."
When discussing his successes over the past year and future priorities, Kennedy focused on bringing back and flipping the food pyramid, removing nine synthetic food dyes, and updating baby formula—though health agencies have made little progress on this last priority. According to Katelyn Jetelina, founder of Your Local Epidemiologist, the administration hasn't addressed the "root cause" of health issues but has pursued "headline wins" instead.
Polling Reveals Political Risks
Among voters surveyed in the 35 most competitive congressional districts, researchers Tony Fabrizio and Bob Ward found "strong bipartisan support for routine childhood vaccines" in December. This support holds across the Maha movement, with most Maha voters rejecting changes to childhood immunizations. They concluded that "high levels of trust in vaccines" mean "skepticism toward vaccine requirements is politically risky for both parties."
Elizabeth Jacobs, an epidemiology professor at the University of Arizona and founding member of Defend Public Health, observed: "My perception is absolutely that messaging has gone out to downplay anti-vaccine messaging. It seems like somebody has advised him to stop doing anti-vaccine stuff."
Subtle References and Continued Opposition
Despite the apparent strategic shift, Kennedy made quiet references to his long-held anti-vaccine ideologies. He mentioned watching "this deterioration in the health of our children, the rise of chronic disease, since 2005"—the year he penned an explosive article claiming vaccines cause autism, which was later retracted by Salon. Jacobs noted this reference is "a major glaring sign that he is talking about vaccines, for sure."
At CPAC, Kennedy stated, "I never knew anybody with autism. Suddenly they're everywhere," without acknowledging changes in diagnostic practices or community support systems for autistic individuals. He added, "And when I started talking about it, I got censored. And I prayed every day for 19 years that God would put me in a position to change this." Under Kennedy's leadership, the US ended full recommendations for shots protecting against flu, rotavirus, RSV, and others.
Mixed Messages and Ongoing Concerns
Jay Bhattacharya, head of the National Institutes of Health, mentioned vaccines only once at CPAC—to highlight the potential for shingles vaccination to protect against Alzheimer's disease. However, he repeatedly echoed Kennedy's rhetoric on "chronic disease," a phrase Kennedy frequently uses to refer to autism, stating, "Despite all our scientific progress, I know we are in the middle of a chronic disease crisis."
Meanwhile, ideological allies continue pushing publicly against vaccines. Mark Gorton, president of the Maha Institute, recently called for eliminating all immunizations in the US, stating in March that "The childhood vaccination schedule needs to be eliminated. And all vaccines need to be removed from the market until they can be proven to be both safe and effective."
At the same event, longtime Kennedy ally Del Bigtree declared, "We're winning," urging followers to "be loud and more proud than you've ever been." Brian Hooker, chief scientific officer at Children's Health Defense—the organization Kennedy led until recently—told NPR that anti-vaccine ideology remains "in the forefront" and "on the agenda" for US health officials.
Public Health Consequences
Even as officials temporarily reduce direct discussion of vaccines, misinformation continues to spread alongside measles and other preventable illnesses as vaccination levels drop. Jetelina warned, "We are going to lose lives over this. We are going backwards on a lot of things, and we don't have time to be spinning our wheels." The strategic political silence on vaccines may have significant public health consequences that extend far beyond the upcoming elections.
