β¦ Synopsis
Two hundred and twelve individuals who failed to respond or responded poorly to hepatitis B vaccination or whose anti-HBs levels had dropped below 10 IU/L at follow-up were revaccinated. Only 18% of initial nonresponders, but 96% of those who responded initially, developed anti-HBs above 10 IU/L after revaccination. In 85% of vaccinees, anti-HBs titres after a fourth immunization were significantly higher than after completion of the first full immunization course, and despite a steeper decline of antibody levels after revaccination, anti-HBs seemed to persist better than after the initial course of three inoculations. All individuals who responded initially and in whom anti-HBs had become undetectable developed antibodies. Response to booster doses was seen after three to five days, and a fifth inoculation given to 23 individuals induced even better responses.

Duck hepatitis B virus (DHBV) has been a useful model for hepadnavirus infection. There have been few studies on immunity to DHBV and none describing the cell-mediated immune response by acute and chronically infected ducks.

Nineteen healthy young adults were vaccinated with plasma-derived hepatitis B vaccine at months 0, 1, and 12, and their immune responses were compared to those of a similar group of 20 vaccinees immunized at months 0, 1, and 6. Late booster injections at 12 months produced nearly fivefold higher geo
In order to evaluate the true immune status and the effect of revaccination on a young adult population, we collected serum samplesfrom 289 military recruits who were vaccinated during an outbreak in 1991. Most vaccinees, age 18-25 years, had apparently been immunized once before as infants. Sera co
