National, Regional, State, and Selected Local Area Vaccination Coverage Among Adolescents Aged 13–17 Years — United States, 2015

Abstract

Local areas that received Federal Section 317 immunization funds were sampled separately: Chicago, Illinois; New York, New York; Philadelphia County, Pennsylvania; Bexar County, Texas; and Houston, Texas. Two local areas (in Texas) were oversampled: El Paso County and Hidalgo County. Three territories was sampled separately in 2015: Guam, Puerto Rico, and the U.S. Virgin Islands. ¶ All identified cellular telephone households were eligible for interview. Sampling weights were adjusted for dual-frame (landline and cellular telephone), nonresponse, noncoverage, and overlapping samples of mixed telephone users. A description of NIS-Teen dual-frame survey methodology and its effect on reported vaccination estimates is available at http://www.cdc. gov/vaccines/imz-managers/coverage/nis/child/dual-frame-sampling.html. ** The overall Council of American Survey Research Organizations (CASRO) response rate was 33.0%. Response rates for the landline and cell phone samples were 56.4% and 29.8%, respectively. For completed interviews in the states and local areas, 4,784 landline calls (53.4%) and 17,091 cell phone calls (48.9%) had adequate provider data. Overall, for states and local areas, 22% of completed interviews with adequate provider data were from landlines and 78% were from cell phones. For U.S. territories, the landline and cell phone sample CASRO rates were 52.1% and 22.6% for Guam, 57.8% and 37.4% for Puerto Rico, and 69.6% and 41.5% for the U.S. Virgin Islands, respectively. The CASRO response rate is the product of three other rates: 1) the resolution rate (the proportion of telephone numbers that can be identified as either for business or residence), 2) the screening rate (the proportion of qualified households that complete the screening process), and 3) the cooperation rate (the proportion of contacted eligible households for which a completed interview is obtained National Vaccination CoverageIn 2015, among males, coverage with ≥1 HPV vaccine dose was 49.8% and with ≥3 doses was 28.1%; among females coverage with ≥1 dose was 62.8% and with ≥3 doses was 41.9% (Table 1) (Figure 1) Vaccination Coverage by Selected CharacteristicsIn 2015, ≥1-dose HPV vaccination coverage among females aged 13 years was lower than coverage among females aged ≥15 years, but was similar among males in all age groups (Table 1). Although HPV vaccination coverage remained higher among females than among males, the percentage point difference in coverage estimates decreased over time (Figure 1). Coverage with each HPV vaccine dose and with ≥1 MenACWY dose was higher among Hispanic adolescents than among non-Hispanic white (white) adolescents; however, coverage with ≥2 measles, mumps, and rubella vaccine (MMR) doses and ≥3 hepatitis B vaccine doses was lower among Hispanic adolescents (Table 2). Coverage with ≥1 HPV vaccine dose was higher among non-Hispanic black (black) adolescents, compared with white adolescents. Adolescents living below the federal poverty level had higher ≥1-and ≥2-dose HPV vaccination coverage than did a...

Timing Is Everything: Exploring Parental Decisions to Delay HPV Vaccination

“…Although several studies have shown that HPV vaccination does not affect subsequent sexual behavior (Liddon, Leichliter, & Markowitz, 2012) and that overall HPV vaccination is both safe and effective in reducing HPV prevalence (Markowitz et al, 2013), vaccination rates remain low across adolescents in the United States, with only 39.7% of girls and 21.6% of boys aged 13 to 17 estimated to have completed the series in 2014 (Reagan-Steiner et al, 2015). Although there was a slight increase in the overall vaccination completion rate in females from the previous year, the rate of uptake for HPV vaccination continues to lag behind other adolescent vaccines, resulting in a pressing need to identify effective ways of increasing uptake across different populations (Ferrer, Trotter, Hickman, & Audrey, 2014;Fu, Bonhomme, Cooper, Joseph, & Zimet, 2014;Mayne et al, 2012;Perkins et al, 2015).…”

Parents who refuse or delay HPV vaccine: Differences in vaccination behavior, beliefs, and clinical communication preferences

“…1 In the extensive research literature that seeks to explain low HPV vaccination coverage, many studies have focused on parents of adolescents because they are most often responsible for making HPV vaccination decisions. 2 These studies, including our own, have typically examined the relationship between parents' vaccination beliefs, their intention to vaccinate their adolescents, and adolescents' ultimate vaccination status.…”

Should we lower the age for routine HPV vaccination in the United States?

“…Another important concern is that only 2 in 5 girls and 1 in 5 boys aged 13-17 years in the US have received the recommended full series (three doses) of the vaccine (Reagan-Steiner et al, 2015). Low uptake is regarded as the primary obstacle to attaining the goal of reducing morbidity and mortality associated with HPV infection.…”
