What Is the Rate of Compliance With Current Recommendations for Hepatitis A Vaccination?
The Centers for Disease Control and Prevention recently reported that 52% of children aged 19-35 months born between January 2008 and May 2010 had received the recommended ≥ 2 doses of the hepatitis A vaccine. Another recent report evaluated adolescent hepatitis A vaccine coverage in the United States using provider-reported vaccination data. In 2009, national 1-dose hepatitis A vaccine coverage among adolescents was 42%; overall, only 30% had received 2 doses. The adjusted prevalence ratios for vaccination initiation were highest for states with a vaccination requirement and for adolescents whose providers recommended the hepatitis A vaccine. Low coverage among most adolescents in the United States in 2009 renders a large population susceptible to HAV infection as they mature into adulthood.
Compliance Among High-Risk Groups
Since 1996, hepatitis A vaccine has been recommended for adults at increased risk for infection, including travelers to intermediate or high hepatitis A endemic countries. In 2009, travel outside the United States and Canada was the most common exposure reported for persons with HAV infection. Lu and colleagues analyzed data from the 2010 National Health Interview Survey to determine self-reported hepatitis A vaccination coverage among adults who traveled to a country of intermediate or high HAV endemicity. In 2010, 37% of adults reported traveling to endemic countries; among this group, vaccination coverage was 27% compared with 13% among nontravelers. They concluded that during patient encounters, healthcare providers should inquire about upcoming travel plans and recommend travel-related vaccinations. Furthermore, despite recommendations to vaccinate against HAV in patients with chronic hepatitis C infection, physicians often do not test or vaccinate susceptible individuals. Interventions are needed to overcome the barriers identified and improve vaccination rates.
