What is Nobivac® Bb for cats?
Developed by Intervet, Nobivac® Bb for cats is a vaccine containing an avirulent live culture
of Bordetella bronchiseptica for the prevention of disease in cats caused by this bacteria.
Which cats should I consider vaccinating with Nobivac® Bb for cats?
As with all vaccines, vaccination should be performed according to a risk-assessment performed
by the veterinarian under the consultation of the requirements of the owner. Typically,
Nobivac® Bb for cats should be given to all cats (alongside the usual Nobivac® Tricat or Forcat)
where the owner requires the most comprehensive protection available against feline URTD. In
addition, Nobivac® Bb for cats should be recommended for the following high-risk groups:
Cats from multicat households (3 or more cats)
Cats being boarded
Cats in breeding catteries
Cats in rescue shelters
Cats in contact with dogs with a recent history of respiratory disease
Kittens, especially those obtained from rescue shelters and breeding catteries
How is Nobivac® Bb for cats administered?
Nobivac® Bb for cats is an easy-to-administer, low-volume dose (0.2 ml), single nostril,
intranasal vaccine that can be given to kittens as young as 4 weeks of age. Safely.
Effectively. Reliably.
Why have Intervet developed an intranasal rather than an injectable vaccine against
Bordetella bronchiseptica?
Intranasal Bordetella bronchiseptica vaccines have been shown to provide dual
protection by inducing a local mucosal
immune response and a systemic response. Local immune responses work rapidly even in the face
of maternally derived antibody. Our studies have shown that Nobivac® Bb for cats works quickly,
even in young kittens. This is particularly important for the most at-risk including: cats
entering catteries and kittens which are obtained from breeders or rescue shelters.
Furthermore, intranasal vaccination with Nobivac® Bb for cats is pain-free and causes no local
reactions.
What happens if the cat sneezes after vaccination?
The vaccine has been formulated such that it will be effective even though cats sneeze
immediately after vaccination - this is perfectly normal and does not affect the efficacy of
vaccination in any way.
What is the duration of immunity of Nobivac® Bb for cats? Duration of immunity studies have shown that protection lasts
for 1 year. For continual protection against Bordetella bronchiseptica infection, it is recommended that kittens and
cats receive an annual dose of Nobivac® Bb for cats. Otherwise, cats should be vaccinated at
least 72 hours prior to stressful situations and when risk of exposure exists, such as
boarding, transporting, breeding or participating in cat shows.
What types of reactions may occur with Nobivac® Bb for cats?
In field trials field safety studies 98% of vaccinated cats
were reaction-free. Those reactions reported were all mild in nature and all affected cats
recovered uneventfully. The most common sign was transient sneezing 48-72 hours post
vaccination. Sneezing was self-limiting and resolved without treatment.
What advise do I give clients who own rescue shelters, boarding and breeding catteries? Bordetella bronchiseptica can be a considerable problem in these environments leading to outbreaks of severe
respiratory disease and kitten mortality. Nobivac® Bb for cats should be included in the
existing vaccination program to help reduce the incidence of morbidity and mortality and the
requirement for antibiotic therapy. Your clients should be advised to visit the
Cattery section of this site for more information.
Can Nobivac® Bb for cats be given with antibiotics?
No. Vaccines should only be administered to healthy animals. Nobivac® Bb for cats contains an
avirulent live strain of bacteria; consequently, an antibiotic could inactivate the vaccine
strain. Therefore, an animal that has been on antibiotic treatment should not receive Nobivac®
Bb for cats until after the antibiotic has been eliminated from the body, which is generally
48 to 72 hours after cessation of treatment. If antibiotics are given within 1 week of
vaccination with Nobivac® Bb the vaccination should be repeated after the antibiotic course
has been completed.
