From August 2014 to June 2015, 353 individuals were interviewed and tested for markers of HBV infection. Overall HBV prevalence was 21.8% (95%CI: 17,82-26,41), and 19,5% (95%CI: 15,75-24,0) showed a serological profile of previous HBV vaccination.

We found overall anti-HAV prevalence elevated in this San Francisco homeless population compared with the general U.S. population. These data show that anti-HAV was associated with homelessness independent of other known risk factors, such as being foreign-born, race/ethnicity, and injection drug use. This increase indicates an excess risk of HAV infection and the potential need to offer hepatitis A vaccination as part of homeless services.

“…Risk‐taking behaviour among our population of persons subject to homelessness was high, yet around 69% of the clients remained vulnerable to hepatitis A, B or both, and had the potential to benefit from vaccination 20 . The prevalence of hepatitis B carriage was higher than the general Australian population, as was the proportion of clients with antibodies to hepatitis C 20 . Both of these serological markers may be associated with chronic liver disease, putting this population further at risk if exposed to additional hepatic infection.…”

“…Therefore, we undertook this study of people subject to homelessness within the inner city area of Sydney to identify risk factors for hepatitis, determine the serological prevalence of markers for hepatitis A, B and C and to determine the acceptance, completion rates and immunogenicity of the standard vaccination schedule for hepatitis A and B. The results of the risk factor and serological survey are reported elsewhere 20 . This paper reports the results of vaccination acceptance, completion rates and immunogenicity of vaccines against hepatitis A and B.…”

Objectives: To determine acceptance, completion rates and immunogenicity of the standard vaccination schedule for hepatitis A (HAV) and B (HBV) in persons subject to homelessness. Methods: A convenience sample of clients (n=201) attending a medical clinic for homeless and disadvantaged persons in Sydney was enrolled. Serological screening for HAV and HBV was undertaken. An appropriate vaccination program was instituted. Post‐vaccination serology determined serological response. Results: Although many clients had serological evidence of past infection, at least 138 (69%) clients had the potential to benefit from vaccination. For hepatitis A and B vaccinations, completion rates were 73% (73 of 100 clients) and 75% (69 of 92 clients), respectively; after vaccination, protective antibody was found in 98.2% (56 of 57) and 72% (36 of 50) of clients, respectively. Conclusion: A successful vaccination program can be mounted with a vulnerable population. We consider a clinic with a well‐established history of acceptance and utilisation by the target group; a low staff turnover and regular clientele; inclusion of vaccination as part of routine client care; and counselling (part of pre‐ and post‐serological testing) essential components in achieving good vaccination completion rates.
