Using a statewide sample, we evaluated whether survivors are at higher risk of missed opportunities for concomitant HPV vaccination.<h4>Methods</h4>From statewide healthcare data, we identified encounters where vaccines were received. Concomitant HPV vaccine missed opportunities were defined as a vaccine encounter where the HPV vaccine was not administered, although eligibility criteria were met. From these encounters, our sample included 327 survivors identified from the Utah Cancer Registry, diagnosed 2000-2016 at ages 0-9, and a birth year and sex-matched sample without cancer from the general populCancer medicineMissed opportunities for concomitant HPV vaccination among childhood cancer survivors.PMC8855920NU58DP006320R03 CA216174HHSN261201800016IRamsay JMKaddas HKOu JYKepka DKirchhoff ACfalseMissed opportunities for concomitant HPV vaccination among childhood cancer survivors.<h4>Purpose</h4>Childhood cancer survivors are at higher risk of human papillomavirus (HPV)-related second cancers than adolescents without cancer, yet their HPV vaccination uptake is lower.
