3. CLINICAL INFORMATION

3.1 Target species

Dogs.

3.2 Indications for use for each target species

For the active immunisation of dogs to reduce clinical signs of disease caused by canine distemper virus infection; to prevent clinical signs and viral excretion caused by canine parvovirus infection; to reduce clinical signs of canine contagious hepatitis and viral excretion due to canine adenovirus 1 infection and to reduce clinical signs of respiratory infection and viral excretion caused by adenovirus type 2 infection.

Onset of immunity: 1 week.

Duration of immunity: 3 years.

3.3 Contraindications None.

3.4 Special warnings

Vaccinate healthy animals only.

The efficacy of the CDV (canine distemper virus), CAV2 (canine adenovirus 2) and CPV (canine parvovirus) components of the vaccine may be reduced due to maternal antibody interference. However, the vaccine has been proven to be of benefit against virulent challenge in the presence of maternal antibody levels to CDV, CAV2 and CPV that are likely to be encountered under field conditions.

3.5 Special precautions for use

Special precautions for safe use in the target species:

Dogs should not be exposed to unnecessary risk of infection within the first 2 weeks after completion of the vaccination regimen.

While the canine parvovirus vaccine strain may be shed at very low levels for up to 8 days after inoculation, there is no evidence that this results in clinical symptoms if nonvaccinated animals are infected.

Special precautions to be taken by the person administering the veterinary medicinal product to animals:

In case of accidental self-injection, seek medical advice immediately and show the package leaflet or the label to the physician.

Special precautions for the protection of the environment: Not applicable.

3.6 Adverse events Dogs:

Common (1 to 10 animals / 100 animals treated):	Injection site swelling[1].
Rare (1 to 10 animals / 10,000 animals treated):	Elevated temperature[2]. Hypersensitivity reaction (e.g. lethargy, facial oedema, pruritus, dyspnoea, vomiting, diarrhoea or collapse, including anaphylaxis)2.
Very rare (<1 animal / 10,000 animals treated, including isolated reports):	Immune mediated haemolytic anaemia, immune mediated thrombocytopenia, immune mediated polyarthritis.

Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for respective contact details.

3.7 Use during pregnancy, lactation or lay

Pregnancy:

Can be used in pregnant bitches which have previously been vaccinated with the CDV (strain Onderstepoort), CAV2 (strain Manhattan LPV3) and CPV (strain 154) antigens included in the Canigen vaccine range.

3.8 Interaction with other medicinal products and other forms of interaction

Safety and efficacy data are available which demonstrate that this vaccine can be mixed and administered with the inactivated vaccines of the Canigen range against canine leptospirosis caused by all or some of the following serovars: L. interrogans serogroup Canicola serovar Canicola, L. interrogans serogroup Icterohaemorrhagiae serovar Copenhageni, L. interrogans serogroup Australis serovar Bratislava, and L. kirschneri serogroup Grippotyphosa serovar Bananal/Liangguang.

After administration with one of the leptospirosis vaccines, a mild and transient increase in body temperature (≤ 1 °C) may occur for a few days after vaccination, with some pups showing less activity and/or a reduced appetite. A small transient swelling (≤ 4 cm), which can occasionally be firm and painful on palpation, may be observed at the site of injection. Any such swelling will either have disappeared or be clearly diminished by 14 days postvaccination.

After mixed administration of an overdose of this vaccine and an overdose of the leptospirosis vaccines in the Canigen range, transient local reactions such as diffuse to firm swellings from 1 to 5 cm in diameter may be observed, usually these will persist no longer than 5 weeks, however some may take a little longer to completely disappear.

Safety and efficacy data are available which demonstrate that this vaccine can be mixed and administered with the inactivated vaccine in the Canigen range against rabies. After administration with the rabies vaccine, where this product is authorised, transient local reactions such as diffuse to firm swellings from 1 to 4 cm in diameter may be observed for up to 3 weeks after vaccination. The swellings may be painful for up to 3 days post dosing.

Safety and efficacy data are available which demonstrate that this vaccine can be administered on the same day, but not mixed, with the live vaccine for intranasal administration in the Canigen range against infectious tracheobronchitis caused by Bordetella bronchiseptica and/or canine parainfluenza virus.

Safety and efficacy data are available which demonstrate that this vaccine can be administered at the same time but not mixed with the inactivated vaccine in the Canigen range against Bordetella bronchiseptica.

When this vaccine is used with any of the other Canigen vaccines referred to above, the minimum vaccination age for each vaccine must be taken into account such that at the time of vaccination, the dogs are at or older than the oldest minimum vaccination age for the individual vaccines.

Consult product leaflets before administering products simultaneously.

No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product except the products mentioned above. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case by case basis.

3.9 Administration routes and dosage

Subcutaneous use.

Reconstitute immediately prior to use by the addition of the contents of one vial (1.0 ml) of the solvent provided or the vaccines in the Canigen range against rabies or leptospirosis as mentioned in section 3.8 (where these products are authorised). Sterile equipment should be used for administration.

Avoid contamination of vaccine with traces of chemical sterilising agents. Do not use chemicals such as disinfectant or spirit to disinfect the skin prior to inoculation.

Vaccination programme Primary vaccination:

A single injection should establish active immunity in dogs of 10 weeks of age or older. Where earlier protection is required a first dose may be given to puppies from 6 weeks of age, but because maternally derived passive antibodies can interfere with the response to vaccination a final dose should be given 2 – 4 weeks later i.e. at 10 weeks of age or older.

Revaccination:

To maintain protection a single dose is recommended every 3 years.

Reconstituted product: off-pink or pink coloured suspension.

3.10 Symptoms of overdose (and where applicable, emergency procedures and antidotes)

No clinical signs other than those indicated in section 3.6.

3.11 Special restrictions for use and special conditions for use, including restrictions on the use of antimicrobial and antiparasitic veterinary medicinal products in order to limit the risk of development of resistance

Not applicable.

Not applicable.
