Vaccine Adherence: Addressing Myths and Hesitancy
Full update August 2022
Determining which vaccines are appropriate for your patient is based on several factors (e.g., age, health conditions, lifestyle). Patient fears, myths, and scheduling may be barriers to vaccine adherence. Use this checklist to improve vaccination rates, increase adherence, and overcome barriers.
Goal |
Suggested Approach |
Identify candidates
|
☐ Ask about vaccine history. For example, you can ask:
☐ Use these tools to stay current on available vaccines and the latest recommendations for all age groups:
☐ When available, review immunization registry data to determine which vaccine(s) a patient may need. ☐ Develop strategies to identify eligible patients. Consider patient ages and chronic medical conditions. For example:1,2
☐ Be familiar with and follow policies for giving vaccines to minors with and without parental consent.
|
Address hesitancy
|
☐ Ask about vaccine hesitancy. For example, you can ask, “What keeps you or your child from getting a recommended vaccine?” ☐ Infants: Ease fears about the number of vaccines infants receive at one time. Evidence suggests that a healthy child’s immune system will NOT be damaged or overwhelmed by receiving multiple vaccines at once.3 ☐ Adolescents: Reassure that the HPV vaccine does NOT increase sexual promiscuity or sexually related outcomes (e.g., pregnancy).4 ☐ Adults: Educate that vaccines not only prevent infections, but also significant infection-related complications.
|
Ease fears about unfounded myths
|
☐ Ask about fears and questions. For example, you can ask, “What fears or questions do you have because of things you have heard about vaccines?” ☐ Remind patients that the flu vaccine may cause mild malaise or flu-like symptoms, but it does NOT cause the flu.6 ☐ Tell patients that they can’t believe everything they see on the internet about vaccines, as some of the information is false. But reassure them that studies consistently show that vaccines (even old ones that had thimerosal) DO NOT cause autism.7 ☐ Some prefer natural immunity over vaccines. It is not worth the risk, especially for some infections.
|
Improve adherence
|
☐ Use strong endorsements. ☐ Consider using an “opt-out” approach instead of an “opt-in” approach.
☐ Personalize the conversation. Share that you vaccinate your kids. Ask if they were vaccinated when they were young. ☐ In the US, encourage booking future vaccine doses with the first dose. Enroll patients in reminder programs (e.g., calls, texts). ☐ In Canada, follow school vaccination programs (where available) to ensure required vaccines are received on schedule. ☐ Suggest coordinating care with other providers who offer vaccines (e.g., pharmacies, other medical appointments).
