Vanguard B (IN)

Company: Zoetis

Bordetella Bronchiseptica Vaccine

Avirulent Live Culture

PRODUCT DESCRIPTION: Vanguard B (IN) is for vaccination of healthy dogs and puppies at least 3 weeks of age or older as an aid in preventing kennel cough caused by Bordetella bronchiseptica. Vanguard B (IN) is composed of an avirulent live culture of B. bronchiseptica bacteria.

DISEASE DESCRIPTION: B. bronchiseptica is considered to be one of the primary etiologic agents of canine infectious tracheobronchitis. The vaccination of dogs with live avirulent B. bronchiseptica has been demonstrated to greatly reduce the severity of the disease. The advantages of Vanguard B (IN) include: 1) induction of good local immune response, 2) competitive inhibition of colonization of wild-type bacteria, 3) administration of a single dose, and 4) lack of administration site reaction.

SAFETY AND EFFICACY: The safety of Vanguard B (IN) was demonstrated by in-house and field safety studies. A total of 655 dogs were vaccinated according to label recommendations. One of the 655 vaccinates was reported to have intermittent sneezing for 2 days following vaccination. No treatment was required. None of the remaining 654 dogs had any adverse reaction to the vaccination.

A challenge model was used to evaluate the efficacy of Vanguard B (IN). The antigen blockage effect was also determined of a modified live canine parainfluenza virus (CPI) vaccine administered concurrently.

A total of 42 puppies 3-5 weeks old were used for the study. Twelve were vaccinated with a monovalent B. bronchiseptica vaccine, 20 were vaccinated with a B. bronchiseptica/CPI combination vaccine, and 10 were vaccinated with a CPI vaccine. The group receiving the monovalent CPI served as the control group for B. bronchiseptica challenge and the group vaccinated with monovalent B. bronchiseptica vaccine served as the control group for the CPI challenge. The route of vaccination for all vaccines was intranasal. Blood and tracheal swabs were taken on the day of vaccination and weekly thereafter. Three weeks after vaccination, all dogs were challenged with virulent B. bronchiseptica and observed for clinical signs of tracheobronchitis (presence of coughing) for 2 weeks. None of the dogs vaccinated with B. bronchiseptica developed tracheobronchitis after challenge whereas the control dogs (CPI vaccinates) showed clinical signs which were frequently observed during the first week after challenge.
