Abstract
The goal year for the Healthy People 2010 initiative is approaching.
This article aims to assess progress toward reaching the overarching goal of eliminating
disparities in vaccination coverage among young children in the U.S.
Coverage for the 4:3:1:3:3:1 vaccine series (at least four doses of diphtheria-tetanus-pertussis,
three poliovirus, one measles-mumps-rubella, three hepatitis B, three Haemophilus
influenzae type B, and one varicella vaccine) was assessed among 185,516 children
in the 2000-2008 National Immunization Surveys. Observed and adjusted disparities
in coverage were evaluated for various sociodemographic groups previously associated
with vaccination coverage. Linear trends in disparities were assessed.
In 2000, disparities among population segments were significant (p<0.05) for all sociodemographic
factors assessed except provider participation in the Vaccines for Children program.
By 2008, most disparities were smaller than those in 2000, and racial and urban/suburban/rural
differences were reduced to levels below significance. Disparities between children
living in suburban versus rural localities narrowed approximately 0.5% per year. Vaccination
coverage increased substantially among children in all sociodemographic groups, although
children without siblings were the only group to reach the 80% target by 2008.
Progress has been made toward eliminating vaccination coverage disparities among children
in various sociodemographic groups in the U.S. As the end of the Healthy People 2010
goal period approaches, maintaining and advancing these reductions will require innovative
strategies to reach underserved groups.
