AAP Updates Guidance on Vaccine Communication and Hesitancy

Clinical Guidance

The new report reviews previously published evidence on the spectrum of parental vaccine acceptance — from supporters and “go along to get along” parents to cautious acceptors and fence sitters to vaccine refusers — and the determinants that contribute to hesitancy. They also noted the social inequities that have played a role in vaccine uptake disparities.

“Distrust of health systems based on historic and ongoing discrimination and inequitable access to care are intertwined challenges that contribute to racial and ethnic disparities in vaccine uptake,” the authors wrote. “Although there has been progress in reducing racial, ethnic, and socioeconomic disparities in childhood vaccination coverage, the COVID-19 pandemic made clear how much work is yet to be done.”

The report also reviewed the societal, individual, payer and pediatric practice costs of vaccine refusal. The 1-year cost to taxpayers from the measles outbreak in New York City in 2018-2019, for example, was $8.4 million, excluding vaccination programs.

The report provides background information to equip pediatricians for conversations with parents about vaccines. Since safety is the top concern for vaccine hesitancy among parents, the authors advised pediatricians to be familiar with the process of vaccine testing, emergency use authorization, licensure, approval, recommendations, and safety monitoring, including the Vaccine Safety Datalink, the Vaccine Adverse Event Reporting System (VAERS), the FDA’s Biologics Effectiveness and Safety (BEST) system, and the CDC’s Clinical Immunization Safety Assessment Project (CISA).

“Because vaccines are generally given to healthy individuals to prevent disease, they are held to a higher safety standard than other medications,” the authors wrote before providing a summary of the process for physicians to reference. The report also includes information on vaccine ingredients and a chart of common misconceptions about vaccines with the corresponding facts.
 

Overcoming Hesitancy

Evidence-based strategies for increasing childhood vaccine uptake begin with a strong vaccine recommendation using a presumptive rather than participatory approach, the authors wrote. “A presumptive format is one in which the clinician asserts a position regarding vaccines using a closed-ended statement, such as ‘Sara is due for several vaccines today’ or ‘Well, we have to do some shots,’ ” the authors wrote. “This strategy is in contrast to a participatory format, in which an open-ended question is used to more explicitly invite the parent to voice an opinion, such as ‘How do you feel about vaccines today?’ ” The presumptive format and a strong recommendation are both associated with greater uptake, evidence shows.

For parents who express hesitancy, the authors provide a summary of additional evidence-based communication strategies, starting with motivational interviewing. Two other strategies they highlight include using language to re-emphasize the importance of adhering to the CDC recommended schedule — “He really needs these shots” — and bundling discussion of all recommended vaccines for a visit at once.

“Finally, clinicians can emphasize their own experiences when discussing the need for vaccination, including personal experience with vaccine-preventable diseases and the fact that they and their families are vaccinated because of their confidence in the safety and efficacy of the vaccines,” the authors wrote.

For families who refuse or delay vaccines, the authors reviewed the “ethical arguments both in favor of and against dismissal policies,” noting that nearly all pediatricians who report dismissing families who refuse vaccination are in private practice, since large systems are often unable to dismiss patients. They also point out that fewer pediatricians dismiss families for spreading out vaccines than outright refusing all vaccines.

”Dismissal of child patients of vaccine-refusing parents can be a difficult decision arrived at after considering multiple factors and documented attempts to counsel vaccine-refusing families,” they wrote. “However, if repeated attempts to help understand and address parental values and vaccine concerns fails to engender trust, move parents toward vaccine acceptance, or strengthen the therapeutic alliance, dismissal can be an acceptable option.”

Finally, the authors reminded pediatricians “that vaccine-hesitant parents are a heterogeneous group and that specific parental vaccine concerns need to be individually identified and addressed.” Working with families to discuss their questions and concerns is an opportunity to “build rapport and trust with a family,” they wrote, ”and, ultimately, protect their children from the scourge of vaccine-preventable diseases.”
