Factors Associated with Hepatitis A Vaccination Receipt in One-Year-Olds in the State of Michigan

Abstract EN

The objectives of this study were to determine factors associated with hepatitis A vaccination and to assess overall hepatitis A vaccination coverage levels among one-year-olds in Michigan.

The study population was the first hepatitis A vaccination-eligible birth cohort (n=134 226) enrolled in the Michigan Care Improvement Registry (MCIR) after 2006 recommendations were made to routinely vaccinate all one-year-olds.

All children whose first birthday occurred on or between May 1, 2006 and April 31, 2007 were included in the study population.

Racial/ethnic minorities had increased odds of receiving the hepatitis A vaccination in Michigan, and Medicaid and WIC status modified this relationship.

Fully understanding these relationships will be useful in targeting vaccination outreach and education programs.
