Addressing Immunization Health Disparities.

Vaccines can prevent illness but are effective only if they reach a majority of the population at risk. Disparities based on many factors, such as race and ethnicity, economic status, and rural versus urban locations of residents, are ongoing issues in the United States. Reasons for disparities include cost, access, coverage, attitudes/beliefs, and systems issues. At the government level, programs like Vaccines for Children, Medicaid reform, Medicare, and state efforts funded in part by 317 grants have helped reduce but not eliminate disparities. At a practice level, vaccine disparities can be addressed by community outreach and systems to offer and deliver vaccines.
