Objective: Identify factors influencing injection drug usersí (IDUís) exposure to and vaccination against hepatitis A virus (HAV) and hepatitis B virus (HBV), and settings where IDU access vaccination. Methods: Participants: 15-30 years old; reported injecting non-prescribed drugs at least once in past 6 months; recruited in Los Angeles for a multi-site behavioral intervention. Assessment included computer-administered questionnaire and blood draw. Samples tested for past infection by measuring total HBV core antibody and total hepatitis A antibody. Results: Of 285 individuals, 74% were male, 23% female and 3.2% transgender. Median age was 23 years. Over a third (37%) did not complete high school. Tests showed that 21% had been exposed to HBV and 23% to HAV. Chi-square tests for age and gender showed that 15-21 year-olds and transgender persons were significantly more likely to test HBV-positive (similar but NS results found for HAV). There was a non-significant trend for increasing exposure with higher education. More reported vaccination against HBV (47%) than HAV (31%). The most common reason for no prior vaccination was not knowing a vaccine existed. Community clinics and private physicians most commonly recommended and provided vaccine. Although 78% had been incarcerated, only 10% of these had been vaccinated there. Conclusions: Younger and transgender IDU are at high risk for HBV and HAV. There are multiple missed chances to inoculate them. Providing vaccine in correctional facilities is a key underused opportunity. A trend of increasing infection with schooling may support the CDC recommendation to provide school-age adolescents with HBV vaccine.
