title: Factors associated with hepatitis a vaccination among children 24 to 35 months of age: United States, 2003.
abstract: OBJECTIVE
  In 1999, the Advisory Committee on Immunization Practices made recommendations for hepatitis A vaccination of children according to historic rates of hepatitis A incidence in different regions of the country. The objective of this study was to examine hepatitis A vaccination coverage rates among children living in states with different vaccination recommendations and to examine individual characteristics associated with vaccination.
  
  
  METHODS
  Hepatitis A vaccination status data were collected for children 24 to 35 months of age through the National Immunization Survey, a telephone survey with health care provider-verified vaccination results. Vaccination status data were collected from children in each of the 50 states and 28 selected urban areas.
  
  
  RESULTS
  In 2003, 50.9% (95% confidence interval [CI]: 47.6-54.2%) of children living in 11 states where routine hepatitis A vaccination is recommended had received > or =1 dose, compared with 25.0% (95% CI: 21.8-28.2%) of children in 6 states where vaccination is suggested and 1.4% (95% CI: 1.0-1.8%) of children in 33 states without a recommendation. Coverage was higher among children who lived in urban areas, were Hispanic or American Indian/Alaska Native, or were born to women with less education.
  
  
  CONCLUSIONS
  Hepatitis A vaccination is being targeted successfully to children at higher risk of infection; however, overall vaccination coverage remains lower for hepatitis A vaccination, compared with other routine childhood vaccinations.
