Intervention(s):

Volunteers were assigned (ratio 1:1:1:1) to one of the four treatment groups (recombinant hepatitis B vaccines): one cuban (Heberbiovac HB, CIGB, Havana), two Korean vaccines (Euvax-B, LG Chemical Ltd. and Hepavax-Gene, Greencross Vaccine Corp.), and one Belgian (Engerix B, GlaxoSmithKline). The schedule of administration of the vaccine was three 20?g doses of the HBsAg used intramuscularly (schedule 0-1-2 months).

Key secondary outcomes:

Reactogenicity, adverse events rate in each dose (first 72 hours), 7 and 30 days post-vaccination.
