Canigen DHPPi Immunisation Vaccine for Dogs.
For active immunisation of dogs to prevent mortality and clinical signs caused by canine distemper virus infection. To reduce clinical signs of infectious hepatitis and viral excretion due to canine adenovirus type 1 infection. To prevent mortality, clinical signs and viral excretion following canine parvovirus infection. To reduce clinical signs and viral excretion caused by canine parainfluenza virus infection and to reduce clinical signs of respiratory disease and viral excretion following adenovirus type 2 infection.
An onset of immunity to the canine distemper virus, canine adenovirus and canine parvovirus vaccine components of 1 week and an onset of immunity of 4 weeks to the canine parainfluenza virus vaccine component has been demonstrated following use of the vaccine.
A duration of immunity of at least three years has been established for the canine distemper virus, canine adenovirus and canine parvovirus vaccine components. The duration of immunity for the canine parainfluenza virus component has not been demonstrated, but an anamnestic response is produced in dogs given a revaccination one year after basic vaccination. Annual revaccination with the canine parainfluenza virus vaccine component is recommended.
Dosage and administration
The contents of one vial of reconstituted vaccine should be injected subcutaneously. Reconstitute immediately prior to use by the addition of the contents of one vial (1.0 ml) of Canigen Lepto 2, Canigen Rabies, or Canigen Solvent.
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.
Primary Course Vaccination
A single injection should establish active immunity to canine distemper, infectious canine hepatitis and disease caused by canine parvovirus infection 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 antibody can interfere with the response to vaccination a final dose at 10 weeks of age or older is generally recommended. For an optimal response to the parainfluenza component, animals should be vaccinated twice, 2-4 weeks apart with the final vaccination at 10 weeks of age or more.
It is recommended that dogs be revaccinated with canine distemper virus, canine adenovirus and canine parvovirus every 3 years and against canine parainfluenza virus every year.
It was not possible to produce clinical signs of kennel cough by parainfluenza challenge in adult dogs and duration of immunity could not therefore be demonstrated, but an anamnestic response was seen in dogs given a booster one year after primary vaccination. Revaccination against parainfluenza is recommended prior to exposure to high risk environments (such as kennelling, showing or mixing with dogs of unknown vaccination history).
Experience has shown that the maternal antibody status of pups within a litter varies greatly and reliance should not be placed on serological examination of the bitch alone.
A good immune response is reliant on the reaction of an immunogenic agent and a fully competent immune system. The immunogenicity of the vaccine antigen will be reduced by poor storage or inappropriate administration. Immunocompetence of the animal may be compromised by a variety of factors including poor health, nutritional status, genetic factors, concurrent drug therapy and stress.
Can be used in pregnant bitches which have previously been vaccinated with the CDV (strain Onderstepoort), CAV2 (strain Manhattan LPV3), CPV (strain 154) and CPi (strain Cornell) antigens included in the Canigen vaccine series.
Contra-indications, warnings, etc
Only healthy dogs should be vaccinated. The vaccine may not be effective in dogs incubating the disease at the time of vaccination.
Some animals may be immunologically incompetent and fail to respond to vaccination. Animals that have received the corresponding anti-serum or immunosuppressive drugs should not be vaccinated until an interval of at least 4 weeks has elapsed.
A diffuse swelling, up to 5 mm in diameter, may be observed at the site of injection. Occasionally this swelling may be hard and painful and last for up to 3 days post injection.
After subcutaneous administration with Canigen Rabies and/or Canigen Lepto 2, a transient palpable nodule may occasionally occur at the site of injection.
In the rare event of a hypersensitivity reaction occurring following vaccination, administer an antihistamine, corticosteroid or adrenaline, without delay and by the most immediate route.
After administration of an overdose, a response similar to that following a single dose may be seen. In some dogs the swelling may be more painful or may be observed for a longer period.
The canine parvovirus vaccine strain may be shed at very low levels for up to 8 days after inoculation. However there is no evidence of any reversion to virulence of the vaccine strain and therefore no need to separate unvaccinated dogs from contact with recently vaccinated individuals.
No information is available on the use of this vaccine with any other, except Canigen Lepto 2 or Canigen Rabies. These liquid vaccines can be used to reconstitute the freeze-dried Canigen DHPPi. It is recommended that no other immunological product should be administered within 14 days before or after vaccination with Canigen DHPPi.
Do not mix with any other medicinal product except Canigen Lepto 2 or Canigen Rabies.
The efficacy of the CDV, CAV2, CPV and CPi components of the vaccine may be reduced due to maternal antibody interference. However, the vaccine has been proved to be of benefit against virulent challenge in the presence of maternal antibody levels to CDV, CAV2, CPV and CPi that are likely to be encountered under field conditions.
For animal treatment only. Keep out of reach and sight of children.
Store between +2°C and +8°C. Do not freeze. Protect from light.
After reconstitution: use within 30 minutes.
Care should be taken to avoid prolonged or repetitive exposure to high ambient temperatures following withdrawal from the refrigerator prior to use - in hot summer conditions vaccine potency can be severely reduced within a few hours.
Dispose of waste material by boiling, incineration or immersion in an appropriate disinfectant approved for use by the competent authorities.
