Hepatitis B vaccination among adolescents 13-17 years, United States, 2006-2012.

BACKGROUND

Hepatitis B (HepB) vaccination is the most effective measure to prevent HBV infection. Routine HepB vaccination was recommended for infants in 1991 and catch-up vaccination has been recommended for adolescents since in 1995. The purpose of this study is to assess HepB vaccination among adolescents 13-17 years.

METHODS

The 2006-2012 NIS-Teen were analyzed. Vaccination trends and coverage by birth cohort among adolescents were evaluated. Multivariable logistic regression and predictive marginal models are used to identify factors independently associated with HepB vaccination.

RESULTS

HepB vaccination coverage increased from 81.3% in 2006 to 92.8% in 2012. Coverage varied by birth cohort and 79-83% received vaccination before 2 years of age for those who were born during 1995 and 1999. Among those who had not received vaccination by 11 years of age, for the 1993-1995 birth cohorts, 9-15% were vaccinated during ages 11-12 years, and 27-37% had been vaccinated through age 16 years. Coverage among adolescents 13-17 years in 2012 ranged by state from 84.4% in West Virginia to 98.7% in Florida (median 93.3%). Characteristics independently associated with a higher likelihood of HepB vaccination included living more than 5 times above poverty level, living in Northeastern or Southern region of the United States, and having a mixed facility as their vaccination provider. Those with a hospital listed as their vaccination provider and those who did not have a well-child visit at age 11-12 years were independently associated with a lower likelihood of HepB vaccination.

CONCLUSIONS

Efforts focused on groups with lower coverage may reduce disparities in coverage and prevent hepatitis B infection. Parents and providers should routinely review adolescent immunizations. Routine reminder/recall, expanded access in health care settings, and standing order programs should be incorporated into routine clinical care of adolescents.
