The HPV vaccine: Are dosing recommendations being followed?

Abstract

The aims of this study were to determine the percentage of females who after initiating the human papillomavirus (HPV) vaccine series, both completed it and completed it on-time, as well as to examine factors associated with series completion and on-time completion. Using data from the North Carolina Immunization Registry, of 138,823 females analyzed, 55% completed the series, and 28% completed it on-time. Over 83% of those who initiated the vaccine series in 2006 completed it by the final study date, as compared to 32% of those who initiated the vaccine in 2009. On-time dosing rates, however, are declining, and have been hovering at 25% for the last two years of the study. Factors such as African-American race and public funding were significantly associated with lower rates of on-time dosing as well as series completion when compared to White race and private funding, respectively. Among girls and young women who initiate the HPV vaccination series, overall completion rates are low, but if given enough time most of those who begin the series will complete it. Our results suggest that strategies to improve the timely completion of the HPV vaccination series may be needed.

HPV Vaccination Completion and Compliance with Recommended Dosing Intervals Among Female and Male Adolescents in an Inner-City Community Health Center

“…Insurance was a recurring predictor for the duration between vaccine dose 1 and 3, however, in a way that is inconsistent with the findings of other studies [18,32]. Our study shows longer durations between vaccine doses among insured adolescents, especially when combined with site.…”

“…This is consistent with the findings of other studies [18,31,32]. Delaying completion of the series places adolescents at risk for acquiring HPV infection due to gaps in immunologic protection from the vaccine doses.…”

“…In a site-based study [18], completion rates of the 3-dose series were 14 % by 7 months and 28 % by 12 months. Completion within the recommended dosing intervals has been found to be significantly lower for Black adolescents and those who are uninsured or with public insurance [18,32]. Information is lacking on dosing intervals among male adolescents.…”

Evaluation of the frequency of immunization information system use for public health research

“…These 44 manuscripts were produced through research at 18 IIS locations. The most number of manuscripts were affiliated with a university (n = 16), 12,16,17,19,20,24,25,27,[32][33][34]36,40,41,48,55 followed by affiliations with a health department (n = 9). 14,20,22,30,31,38,46,47,49 Other affiliations included the CDC (n = 8), 18 want to use the IIS data for research purposes could be advised to seek such a relationship.…”

A pilot study on the use of a smartphone application to encourage emergency department patients to access preventive services: human papillomavirus vaccine as an example

“…There is also a racial disparity in uptake of the vaccine for pathogenic human papilloma viruses (HPV) with African American women being less likely to complete the three shot series [4][5][6][7][8][9][10][11][12]. The HPV vaccine is recommended to be given routinely to 11-or 12-year-old girls and boys.…”
