Subjects who had participated in an earlier clinical study of experimental vaccination with recombinant HA H5/HK/156/97 and conducted in 1998 [12], were re-enrolled for the present study. In the earlier study, subjects received two doses of rH5 HA in the amounts indicated. The numbers of subjects in each dose category, age, and gender distributions are indicated.
