Federal Health Officials Seek Public Input on Possible Changes to Vaccine Recommendation Categories

Federal health officials are asking the public to weigh in on how vaccine recommendations should be categorized in the United States, opening a new discussion about how federal guidance communicates the strength of recommendations, available evidence, and the role of individual circumstances.

The Department of Health and Human Services (HHS) published a formal request for information on Aug. 24, seeking comments on whether the current framework for federal vaccine recommendations is sufficiently clear and whether additional categories should be considered. The public comment period is scheduled to close on Sept. 20, 2026.

The request was issued under the leadership of HHS Secretary Robert F. Kennedy Jr. and is connected to the administration's broader effort to reconsider childhood vaccine recommendations.

What Are the Current Vaccine Categories?

Federal vaccine recommendations currently use three primary categories.

The first is a routine, or universal, recommendation. Under this approach, vaccination is generally recommended for everyone in a particular age group unless there is a medical reason not to receive the vaccine.

The second category is risk-based vaccination. These recommendations apply to people who have particular medical, occupational, behavioral, or other risk factors. In other words, the recommendation is directed toward a defined group rather than the entire population.

The third category is shared clinical decision-making, sometimes referred to as individual-based decision-making. This approach does not establish a single default decision for everyone. Instead, patients, parents or guardians, and health care providers are expected to consider factors such as medical history, available evidence, individual circumstances, and personal preferences.

According to the HHS notice, routine and risk-based recommendations generally have a default position in favor of vaccination when appropriate. Shared clinical decision-making differs because there is no universal default. The final decision can depend on the individual circumstances of the patient and the discussion with a health care professional.

Why Is HHS Reviewing the Categories?

HHS says it wants to determine whether the existing categories are adequately understood by doctors, patients, and parents.

Officials are also asking whether the categories clearly communicate meaningful differences in the evidence supporting a recommendation, the potential benefits for individuals and communities, and the extent to which personal circumstances should influence a vaccination decision.

Another issue raised by the department is whether the current system unintentionally suggests that informed consent, parental involvement, or discussion with a health care provider applies only when a vaccine falls under shared clinical decision-making.

That question could become particularly important for parents trying to understand what a federal recommendation means in practical terms.

The HHS notice does not itself establish a new vaccine schedule. Instead, it is a request for information that seeks public input before officials consider whether changes to the category structure are appropriate.

Possible Changes Could Create Additional Categories

Federal officials are considering whether the three existing categories are enough or whether different categories could provide more precise guidance.

The HHS document specifically asks whether additional or different categories should be adopted. It also asks officials and the public to consider issues such as the strength of scientific evidence, situations where randomized controlled trial evidence is limited, individual autonomy, religious freedom, legal and programmatic consequences, and communication strategies designed to maintain public trust.

One possibility described in the broader discussion is a category in which vaccination is recommended for certain populations but not for infants.

The precise implications of any new category would depend on future federal decisions. At this stage, the government is collecting information rather than announcing a final replacement for the existing framework.

The Review Comes Amid a Broader Vaccine Policy Debate

The review of vaccine recommendation categories follows a series of policy actions involving childhood immunization recommendations.

On Aug. 10, President Donald Trump signed an executive order titled "Delivering Gold Standard Childhood Vaccine Recommendations for Americans." The order calls for federal childhood vaccine recommendations to be aligned with scientific evidence and practices in other developed countries while emphasizing parental choice and informed consent.

The executive order also identifies groups of vaccines under different recommendation approaches. It calls for continued evaluation of vaccine risk-benefit profiles and directs HHS to develop plans concerning the timing and sequencing of childhood vaccines.

Another provision directs officials to work toward making individual vaccines available as alternatives to combination products, beginning with the measles, mumps, and rubella vaccine, while maintaining access to combination vaccines.

The order gives HHS 90 days to present plans covering several areas, including childhood vaccine scheduling, vaccine safety monitoring, research, and the development of alternative adjuvants.

The newly published request for information is intended to support that broader process, according to HHS.

What Could the Changes Mean for Parents?

For families, the most important issue may be how a revised classification system affects the way vaccine recommendations are communicated.

A change in category does not necessarily mean that a vaccine becomes unavailable. Likewise, a change in a federal recommendation does not automatically determine every state's school vaccination requirements.

The HHS notice explains that federal recommendations are reflected in childhood and adult immunization schedules, while states can have their own laws and regulations concerning vaccination requirements.

The Aug. 10 executive order separately encourages states and territories to review their relevant laws and regulations.

Parents therefore may see continued differences between federal recommendations, state requirements, and individual medical advice.

For patients, the terminology could also matter. A category that emphasizes shared decision-making places greater focus on conversations between health care professionals and patients or parents. Clear explanations of what each category means could help families understand whether a recommendation is intended to apply broadly or primarily to specific circumstances.

Public Comments Are Now Open

People who want to provide feedback have until Sept. 20, 2026, to submit comments regarding the proposed review.

The Federal Register notice lists the matter under HHS Docket No. HHS-OS-2026-0332. Comments can be submitted through Regulations.gov or by mail to the address specified in the notice. HHS also warns that submitted comments will be posted publicly, including personal information contained in a submission.

The public comment process gives parents, health care professionals, researchers, organizations, and other members of the public an opportunity to explain whether they believe the current categories are understandable and useful, or whether a different system would better communicate vaccine recommendations.

For now, no final change to the three-category framework has been announced. The outcome will depend on the comments received, the department's review, and subsequent federal action.

As the administration continues its broader examination of childhood vaccination policy, the debate over how recommendations are classified could become an important part of the discussion about parental choice, clinical decision-making, scientific evidence, and public health.
