Background: Chronic hepatitis B virus is a leading cause of primary liver cancer and cirrhosis, especially among Asian and Pacific Islander immigrants. Vaccination of high-risk groups is critical for controlling HBV.

Objective: This study assessed the vaccination status and vaccine perceptions of high-risk APIs in Philadelphia.

Methods: 935 participants were screened at 17 locations throughout Philadelphia. Participants completed a questionnaire regarding their country of birth, ethnicity, education, and perception of vaccination status. Participants were screened for infection and protection status. Infected individuals were referred to appropriate health care; vulnerable individuals were referred for vaccination. Fisher's exact test was performed to assess the difference between APIs and non-APIs with respect to their vaccine perception.

Results: Overall, 6.4% (n = 60) were infected with HBV and 52.1% (n = 487) had protective antibodies. 6.5% (n = 56) of participants believed they were vaccinated, but had no protective antibodies. Of these participants, 87.5% (n = 49) were immigrants from high-risk countries; 67.9% (n = 38) were female; 39.3% (n = 22) had less than a college degree. There was no significant difference between APIs and non-APIs with respect to their vaccine perception (p > 0.05).

Conclusions: It is critical that those at highest risk for HBV infection be protected via vaccination. This study indicates that some individuals have misconceptions regarding their vaccination status and self-report of HBV vaccine may be unreliable. This suggests the need for HBV education and screening, particularly among the immigrant population.
