RFK's Health Movement Sparks Debate Over Vaccine Decision-Making Approach

The concept of 'shared decisionmaking' has become a central theme in Robert F. Kennedy Jr.'s Make America Healthy Again (MAHA) movement. Jay Bhattacharya, the interim head of the Centers for Disease Control and Prevention (CDC), and Casey Means, the nominee for US Surgeon General, have both emphasized the importance of shared decisionmaking in healthcare, particularly regarding vaccines. This approach involves a dialogue between healthcare providers and patients about the risks and benefits of medical interventions. However, public health experts argue that the MAHA movement is using this concept to cast doubt on vaccines.

Jennifer Nuzzo, an epidemiology professor at Brown University, contends that labeling vaccines as requiring shared decisionmaking suggests uncertainty about their safety and efficacy, which contradicts the established evidence supporting vaccines as a standard of care. The CDC has historically used shared decisionmaking for specific cases where broad vaccination may not have a significant population-level impact, but the MAHA movement's application of this approach to routine vaccines is unprecedented.

In May, the CDC recommended shared decisionmaking for Covid-19 vaccines for healthy children aged 6 months to 17 years. Later, Kennedy's vaccine advisory committee further promoted this approach, moving away from the previous guidance that everyone over six months should receive an annual Covid vaccine. In January, Kennedy bypassed his advisory committee to reclassify several vaccines, including those for hepatitis A and B, influenza, and meningococcal ACWY, from routine recommendations to shared decisionmaking, without new supporting evidence.

The shared decisionmaking concept originated in the 1980s to counteract paternalistic medical practices, particularly in complex medical decisions where no single best option exists. However, experts like Jake Scott from Stanford University argue that this approach is inappropriate for vaccines, which are known to be safe and effective and have significant public health implications.

Historically, shared decisionmaking was applied to vaccines only once before, in 2015, for the meningococcal B vaccine, which does not prevent bacterial transmission. Kathleen Hall Jamieson, a misinformation expert, notes that the reframing of shared decisionmaking creates confusion and suggests a false sense of choice regarding vaccines. A survey by the Annenberg Public Policy Center found that 20% of adults believe shared decisionmaking implies vaccines might not be suitable for everyone.

Despite the CDC's role in providing vaccination guidance, states and local jurisdictions determine vaccine requirements for school entry. Parents can opt out of vaccinations for their children, and the rate of vaccine exemptions is rising, reaching 3.6% for the 2024-25 school year. Scott warns that shared decisionmaking is being used politically to undermine vaccines without outright bans, and he suggests monitoring how this template might be applied in the future.
