Why is shared clinical decision-making (a discussion between the provider and the patient) recommended to determine whether to provide HPV vaccine to an adult age 27 through 45 years?

Although new HPV infections are most commonly acquired in adolescence and young adulthood, having a new sex partner at any age is a risk factor for acquiring a new HPV infection. In addition, some people have specific behavioral or medical risk factors for HPV infection or disease, including men who have sex with men, transgender people, and people with immunocompromising conditions. HPV vaccine works to prevent infection among people who have not been exposed to vaccine-type HPV before vaccination. A discussion with your patient is the best way to decide together how much the patient may benefit from HPV vaccination to prevent new HPV infections.
