This is one of the types of recommendations that the CDC’s Advisory Committee on Immunization Practices can use when it makes recommendations about certain populations getting certain vaccines. Shared clinical decision-making recommendations fall short of a direct universal recommendation for all individuals in a certain age group to receive that vaccine and instead recommend that the provider and individual (or individual’s guardian/caregiver) discuss the risks and benefits of the vaccine given their personal and health history and circumstances and decide together whether it get it.
An example is the meningitis B vaccine, which ACIP recommends shared clinical decision-making for teens. Those going off to live in dorms in college or joining the military, where they’ll be living in barracks, may be likely at higher risk for meningitis B than, for example, a young adult entering the workforce or remaining at home. ACIP recommends the decision be made together with a provider, taking into consideration factors the CDC advises.
Vaccines recommended under shared clinical decision-making are still eligible to be covered by the Vaccines for Children program and by private insurance under the Affordable Care Act. They’re also eligible for reimbursement under the Vaccine Injury Compensation Program for adverse effects that qualify. More information is available at this archived CDC page. You can also learn more information about liability for vaccines recommended under SCDM from this article, written by a law professor specializing in vaccine law.
