It has been shown that antianthrax immunity induced by the novel vacci
ne proposed has not only antitoxic, but also antispore character. The
whole complex of antigens, namely surface spore antigens, surface anti
gens of cell wall and toxin components is required for the induction o
f strong and stable immunity against anthrax. The STI-1 vaccine strain
with introduced resistance to several antibiotics seems to be promisi
ng for prophylaxis and treatment of anthrax in case of emergency, espe
cially if antibiotic pretreatment could be expected. Tile technology f
or submerged cultivation of Bacillus anthracis vaccine strain and for
the development of an anthrax vaccine to be used in human medicine is
proposed on the basis of the conception of the immunogenesis.
