In certain populations (i.e., persons on hemodialysis; persons who are immunocompromised, such as those with HIV infection; sex partners of persons positive for HBsAg; and health care personnel), testing for anti-HBs should be performed one to two months following the completion of the vaccine series.14,15 A responder is defined as a person with an anti-HBs level of 10 mIU per mL or more after completion of the vaccine series.3 If the anti-HBs level is less than 10 mIU per mL after the initial vaccine series, revaccination is indicated.15, Revaccination can be completed using one of two approaches: (1) administration of a second complete hepatitis B vaccine series followed by anti-HBs testing one to two months later, or (2) administration of a single dose of hepatitis B vaccine followed by anti-HBs testing one to two months later.

Lau GK, Terrault NA, Link-Gelles R, If the anti-HBs level remains less than 10 mIU per mL after a single dose, completion of the series should be performed with anti-HBs testing one to two months after completing the series.12 A nonresponder is defined as a person with an anti-HBs level of less than 10 mIU per mL after six doses or more of the hepatitis B vaccine.3, The CDC does not recommend administration of more than two complete hepatitis B vaccine series, except for patients on hemodialysis, in whom anti-HBs testing should be conducted annually and a booster dose of the vaccine administered when the anti-HBs level declines to less than 10 mIU per mL.15,16, Acute hepatitis B is defined as the discrete onset of symptoms (e.g., fever, headache, malaise, anorexia, nausea, vomiting, diarrhea, abdominal pain), the presence of jaundice or elevated serum alanine transaminase (ALT) levels, and test results showing HBsAg and HBcAg.1 A Cochrane review of seven randomized controlled trials with 597 participants found that antiviral treatment has no benefit for acute hepatitis B based on low-quality or very low-quality evidence.17 An individual with acute hepatitis B may achieve complete immune clearance yielding lifelong immunity or develop chronic hepatitis B. ; Annually, approximately 0.5% of individuals with inactive chronic hepatitis B will have spontaneous clearance of HBsAg, and most will develop anti-HBs.2 Among adults with untreated chronic hepatitis B, the cumulative five-year incidence of cirrhosis is 8% to 20%, and the risk of HCC is 2% to 5%.2, The risk of liver-related complications is variable and influenced by a variety of host, viral, and environmental factors.2 Determining the stage of liver disease (e.g., evidence of inflammation, fibrosis) is important to guide therapeutic decisions and the need for HCC screening.2 Although liver biopsy is recommended for assessing inflammatory activity and fibrosis, noninvasive tests, such as transient elastography or a serum fibrosis panel, are also useful.2.
