KRT88P and hepatitis A virus infection: Of which: 84% were immune–either through vaccination (n = 3,565) or past, resolved infection (n = 888); 214 (4%) people were HBV non-immune, meaning a HBsAg, Anti-HBc and Anti-HBs are all negative (and with no evidence of vaccination)–a hepatitis B vaccination care plan was added for these people; 9% (n = 489) of the population had insufficient data to determine a HBV status–HBV testing recalls were added to the primary care EHR so the individual could be offered an HBV test and appropriate action taken when results available.
