This treatment applies to the following species:Feline Calicivirus Vaccine
Killed Virus
For use in animals only
This product has been shown to be effective for vaccination of healthy cats 8 weeks of age or older, against feline calicivirus. The duration of immunity for this product has not been determined. For more information regarding efficacy and safety data, go to productdata.aphis.usda.gov.
The vaccine contains one additional feline calicivirus strain isolated from one hemorrhagic calicivirus outbreak that occurred in 1998 and was shown to be effective for vaccination of cats against calicivirus-induced hemorrhagic disease in controlled vaccination challenge experiments.
Dose: Inject one 0.5 mL dose subcutaneously using aseptic technique. Healthy cats should receive two doses, 3 to 4 weeks apart, except that if the animal is less than 16 weeks of age, the final dose should be given no earlier than 16 weeks of age. The presence of maternal antibody is known to interfere with the development of active immunity in cats and additional boosters will be required in most young animals. Historically, annual revaccination with a single dose has been recommended for this product. The need for this booster has not been established. For advice on revaccination frequency and annual booster vaccinations, consultation with a veterinarian is recommended.
