Nobivac Feline-Bb Intranasal Vaccine for Cats

Nobivac Feline-Bb® is an intranasal vaccine for cats. It helps reduce the risk of respiratory disease caused by Bordetella bronchiseptica. You can access Canadian pricing with US delivery from Canada, even without insurance.

What Nobivac Feline-Bb Is and How It Works

This product is a modified live Bordetella bronchiseptica vaccine given into the nose. The organism stimulates local mucosal immunity in the upper airway, which may help reduce coughing, sneezing, and nasal discharge associated with feline Bordetella infection. It is not an injectable product; it is administered intranasally.

The Nobivac Feline-Bb vaccine is commonly used in shelters, catteries, and multi-cat homes where exposure risk may be higher. Your veterinarian will determine if this preventive fits your cat’s risk profile and vaccination plan. Learn more about the condition at our Feline Bordetella Infection page.

Who It’s For

This vaccine is for healthy cats and kittens of appropriate age per label. It may be considered for cats entering boarding facilities, shelters, or group environments. It can also be used for cats that travel or attend shows where respiratory pathogens circulate.

Do not use in cats that are acutely ill, febrile, or severely immunocompromised, unless directed by a veterinarian. Use caution in pregnant or nursing queens. Discuss any prior vaccine reactions with your clinician. For broader infectious disease prevention context, see our Infectious Disease category.

Dosage and Usage

Administration is intranasal only. A veterinary professional typically reconstitutes the powder with the provided diluent and gives the entire dose into the nostrils, often half the volume per nostril. The label for Nobivac Feline Bb intranasal indicates use as directed by the manufacturer and your veterinarian.

Primary immunization generally involves a single intranasal administration when the cat is of label-specified age. Revaccination plans can vary by exposure risk and clinic protocol; many clinicians recommend periodic boosters. Follow the official label for timing, handling, and aseptic technique. Avoid injecting this product.

Before dosing, allow the reconstituted vaccine to reach room temperature as directed. Minimize stress during handling. After administration, brief sneezing or nasal discharge may occur as the cat clears excess fluid from the nasal passages.

Strengths and Forms

This medicine is supplied as a lyophilized vial with a sterile diluent for intranasal administration. Availability can include unit-of-use packs for clinics and shelters.

• Nobivac Feline-Bb single dose presentation for individual cats
• Multi-dose (often 25-dose) clinic packs with separate diluent vials

Packaging details can vary by lot and market. Your clinic or supplier can confirm which presentations are currently in stock.

Missed Dose and Timing

If a scheduled vaccination or revaccination is delayed, contact your veterinarian. A revised timing plan may be recommended to maintain protection according to risk. Do not administer extra doses without clinical guidance.

If your cat is ill on the day of vaccination, your veterinarian may postpone until recovery. Keep records of all vaccines given, including dates and lot numbers.

Storage and Travel Basics

Unreconstituted vaccine should be kept refrigerated as directed on the label and protected from light. Do not freeze. After mixing, use within the time window specified by the manufacturer. Discard any unused mixed vaccine according to local regulations.

If you are transporting vaccine to a clinic or field site, use an insulated container with cold packs to maintain recommended storage temperatures. Avoid direct contact between vials and ice to prevent freezing. Keep all biologics out of reach of children and pets.

When traveling with your cat to a facility requiring vaccination, bring medical records and proof of prior doses. If documentation is lost, your veterinarian can advise on catch-up plans and whether serologic testing makes sense.

Benefits

As an intranasal product, the treatment targets local mucosal immunity where Bordetella enters the body. This route can be useful for kittens when injections are being minimized, or when rapid practical administration in a group setting is needed. It may help reduce clinical signs in environments with increased exposure pressure.

The class is convenient for clinics and shelters that need quick administration without needles. It also avoids injection site reactions associated with some parenteral products.

Side Effects and Safety

• Mild sneezing or nasal discharge shortly after dosing
• Temporary lethargy or decreased appetite
• Brief eye discharge or watery eyes
• Minor coughing or gagging as fluid is cleared

Serious reactions are uncommon but can include hypersensitivity or anaphylaxis. Seek veterinary care urgently for facial swelling, hives, repeated vomiting, collapse, or breathing difficulty. Cats with a history of severe vaccine reactions may need a tailored plan.

Because this is a modified live vaccine, follow label cautions regarding use with antibiotics or immunosuppressive therapies. Report any unexpected adverse events to your veterinarian.

Drug Interactions and Cautions

Systemic antibiotics started around the time of vaccination may blunt response to live vaccines. Immunosuppressants, including high-dose corticosteroids or certain chemotherapeutics, can reduce vaccine effectiveness. Discuss all medicines, supplements, and recent procedures with your clinician before vaccination.

Do not mix with other vaccines in the same vial unless label-approved. If multiple intranasal products are planned, your veterinarian will sequence them appropriately. Avoid vaccinating clinically ill animals unless the benefits outweigh the risks.

What to Expect Over Time

After intranasal dosing, a cat may sneeze or shake the head briefly. Mild upper-airway signs can occur for a short period. Your clinician will advise on observation and when to return to routine activities.

Ongoing protection requires adherence to the schedule your veterinarian recommends. Keep your cat’s environment clean, reduce overcrowding, and manage stressors to support respiratory health. Good hygiene and quarantine practices for new arrivals further reduce exposure.

Compare With Alternatives

For broader feline respiratory pathogen coverage, many clinics co-administer core viral protection according to protocols. A common option is Feline 3 HCP, which targets viral causes of upper respiratory disease. This complements Bordetella prevention rather than replacing it.

If you manage both cats and dogs, your clinic may also stock canine vaccines for household or shelter needs. For example, Canine 1 DAPPv addresses core viral pathogens in dogs. Ask your veterinarian to align species-appropriate products within a single visit plan.

Pricing and Access

Many buyers compare clinic packs and unit doses based on throughput and storage capacity. Talk with your clinic about the Nobivac Feline-Bb price and which presentation fits your needs. We provide Canadian pricing with US shipping from Canada for eligible orders.

Availability and Substitutions

Supply can vary seasonally or by region. If your clinic’s preferred pack size is unavailable, a prescriber may recommend an alternative presentation or a revised timing plan. When managing multi-species facilities, alternative stock such as Canine Lepto 4 for dogs may be ordered separately if needed.

Your veterinarian will determine appropriate substitutions or deferrals based on risk and regulatory guidance. Do not switch products without professional input.

Patient Suitability and Cost-Saving Tips

This vaccine may suit healthy cats entering higher-risk environments. Kittens often benefit from intranasal administration when needle-based schedules are being built. Cats with chronic respiratory illness may still be candidates, but your clinician will assess current health.

To manage costs, shelters and foster groups often plan multi-cat clinics and select larger presentations where feasible. Set calendar reminders for revaccination planning. For facilities caring for both species, consolidating orders across species-specific products like Canine EDGE 1 DAPPv and Puppy DPV can streamline inventory and reduce last-minute purchases.
