Trends in routine HPV vaccination within ages 9 to 12 years by sociodemographic factors, NIS-Teen, 2008–2018. A, HPV vaccination initiation by sex. HPV vaccination surveys for boys were introduced in 2010, corresponding with the introduction of gender-neutral HPV vaccines, hence data are unavailable for boys in 2008 and 2010. B, HPV-UTD by sex. HPV vaccination surveys for boys were introduced in 2010, corresponding with the introduction of gender-neutral HPV vaccines, hence data are unavailable for boys in 2008 and 2010. HPV-UTD was defined as receiving at least 2 shots of HPV vaccine. Vaccination status between ages 9 to 12 years was derived by using NIS-Teen variables that accounted for age (in days, months, and years) at receipt of HPV shots. These data were unavailable for years 2008–2010. C, HPV vaccination initiation by race and ethnicity. D, HPV-UTD by race and ethnicity. HPV-UTD was defined as receiving at least 2 shots of HPV vaccine. Vaccination status between ages 9 to 12 years was derived by using NIS-Teen variables that accounted for age (in days, months, and years) at receipt of HPV shots. These data were unavailable for years 2008–2010.
