Us health messaging shifts as elections loom: a vaccine retreat?

A subtle but significant shift is underway within US health agencies: a marked reluctance to champion vaccines publicly. As November’s midterm elections draw near and polling data reveals vaccine hesitancy has become a political liability, officials appear to be recalibrating their messaging—a move observers say is driven more by electoral calculations than scientific consensus.

The curious case of dropping recommendations

Just a year ago, the Centers for Disease Control and Prevention (CDC) dramatically altered routine childhood vaccine recommendations, trimming roughly one-third of the schedule, including the once-standard recommendation for hepatitis B immunization at birth. Even before a federal judge’s challenge effectively stalled these changes, there was a notable absence of vigorous defense from agency officials. The timing is particularly noteworthy, coinciding with recommendations from Donald Trump’s pollsters to steer clear of perceived anti-vaccine stances in the lead-up to the midterms.

The influence of the “Make America Healthy Again” (Maha) movement is increasingly visible. At a March conference sponsored by the Department of Health and Human Services (HHS), FDA Commissioner Marty Makary explicitly referenced support for the group, stating, “Moms showed up to vote for the Maha agenda.” This signals a deeper realignment within health messaging priorities.

Robert F. Kennedy Jr, the HHS secretary and a long-time vocal critic of vaccines, further underscored this shift at the Conservative Political Action Conference (CPAC). Instead of reiterating his decades-old concerns about toxic exposures and immunizations, Kennedy pivoted to focus on cell phones and social media as primary health threats—a strategic redirection seemingly designed to resonate with a broader voter base.

Beyond vaccines: a focus on food and environmental concerns

The Maha movement, it turns out, prioritizes environmental and nutritional issues over vaccines. As Katelyn Jetelina, founder of Your Local Epidemiologist, points out, the administration is chasing “headline wins” rather than addressing the “root cause” of health concerns. The recent executive order on glyphosate, a herbicide widely used in agriculture, exemplifies this shift in focus—a direct response to Maha’s opposition to the chemical.

While public opinion surveys reveal “strong bipartisan support for routine childhood vaccines,” particularly in competitive congressional districts, the administration’s actions suggest a different calculation. Elizabeth Jacobs, an epidemiology professor at the University of Arizona, believes messaging has been intentionally muted, observing, “It seems like somebody has advised him to stop doing anti-vaccine stuff.”

Echoes of past controversy and shifting priorities

Despite the current circumspection, Kennedy’s long-standing views haven't entirely disappeared. He alluded to his observations regarding a “deterioration in the health of our children” dating back to 2005—the year he published controversial claims linking vaccines to autism in Rolling Stone and Salon (the latter later retracting the article). These references, however subtle, are a reminder of the deep-seated skepticism that continues to inform his perspective.

The current administration has also scaled back recommendations for flu, rotavirus, and RSV vaccines, drawing criticism from public health experts. Jay Bhattacharya, head of the National Institutes of Health (NIH), echoed Kennedy’s rhetoric on “chronic disease,” adding to concerns about a broader ideological shift within the agency.

Mark Gorton, president of the Maha Institute, has even called for eliminating the childhood vaccination schedule entirely, while fellow activist Del Bigtree proclaimed, “We’re winning.” The reality, however, is that misinformation continues to spread, contributing to declining vaccination rates and a resurgence of preventable illnesses.

“We are going to lose lives over this,” warns Jetelina. The US is, in her assessment, “going backwards on a lot of things.”
