A transient swelling (up to 5 cm) which can be painful, warm or reddened. Any such

after vaccination.
If a hypersensitivity reaction occurs, appropriate treatment should be administered
without delay. Such reactions may evolve to a more severe condition which may be
life-threatening.
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 also section 16 of the
package leaflet for contact details.
A good immune response is reliant on a fully competent immune system.
Immunocompetence of the animal may be compromised by a variety of factors
including poor health, nutritional status, genetic factors, concurrent medicinal therapy
and stress.
Vaccinate healthy animals only.

Special precautions for use in animals
The live attenuated virus vaccine strain CPiV may be shed by vaccinated dogs
following vaccination. However, due to the low pathogenicity of the strain, it is not
necessary to keep vaccinated dogs separated from non-vaccinated dogs.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
