Early development of immunity after hepatitis B vaccination is particularly important for patients such as hemophiliacs, at high risk for acquiring hepatitis B from potentially infectious plasma-derived concentrates. The purpose of this study was to evaluate whether or not protective antibody titers could be achieved quickly and maintained in hemophiliacs by an accelerated vaccination schedule. A yeast-recombinant hepatitis B vaccine (Engerix B, SKF Ritt) was given subcutaneously in the deltoid region and repeated 2 and 6 weeks later to 85 hemophiliacs negative for hepatitis B virus (HBV) markers. After the first 22 patients had been enrolled, a modification of the schedule involving a fourth booster dose 24 weeks after the first dose of vaccine was applied to the next 63 consecutive vaccines. Fifty-three percent of vaccinees had antibody titers to hepatitis B surface antigen (anti-HBs > or = 10 mlU/ml) by week 6, even though the mean titers of anti-HBs were somewhat lower than those achieved historically in normal individuals. The protection rate had increased to 87% by week 10, one month after the third dose of vaccine, and to 93% by week 24. One year after starting vaccination, the rate for the vaccinees who did not receive the fourth booster dose was 71%, and 96% for those who did receive the fourth dose, with only 2 patients not responding despite the booster dose. It is concluded that even though the accelerated schedule of immunization produced rapidly high rates of protective antibody titers, a booster dose is required to obtain higher titers and provide more persistent immunity.
