Vanguard® B Injectable is licensed for the vaccination of healthy dogs 8
weeks of age or older as an aid in the control of canine infectious
tracheobronchitis (kennel cough) caused by Bordetella bronchiseptica
(Bb). Vanguard® B Injectable is prepared from antigenic material
extracted from the Bordetella bronchiseptica organism. A immunogenic
strain of B. bronchiseptica is grown to a high yield, then subjected to
a proprietary process which extracts the antigens from the B.
bronchiseptica cells. The residual cell debris is then removed,
resulting in a product which retains the desirable immunologic qualities
of a whole cell bacterin, while helping reduce toxic and other
undesirable side effects with whole cell bacterins. Vanguard® B
Injectable is a killed cellular extract of the Bordetella bronchiseptica
organism.
