Hepatitis A Vaccination Coverage Among U.S. Children Aged 12-23 Months–Immunization Information System Sentinel Sites, 2006–2009

In this study, CDC reports on assessed hepatitis A vaccine coverage among children aged 12-23 months from 2006-2009, using data from eight Immunization Information System sentinel sites. Average hepatitis A vaccination coverage with =1 dose at the sites increased from 17 percent in 2006 to 47 percent in 2009. Average full vaccination coverage with =2 vaccine doses through age 23 months increased from one percent in 2006 to 15 percent in 2009. Vaccine coverage with =1 dose increased most during 2006 through the first quarter of 2007, then slowed. Findings show that the 2006 Advisory Committee on Immunization Practices (ACIP) recommendation of vaccination coverage for all children aged 12-23 months increased coverage, but coverage has reached a plateau. Immunization programs and providers are advised to continue to encourage hepatitis A vaccination for all children beginning at 12 months of age.
