It is often recommended that the puppy is given a separate Parvo vaccine at about 6 weeks old. (puppys-place.com)
Like the distemper - parvo vaccine in dogs, this vaccine is recommended for all cats starting at age 6 to 8 weeks and is given every 3 weeks for a series of 3 vaccinations.Adult cats should be vaccinated every 3 years. (bayparkpetclinic.com)
I recommend using live parvo vaccine only unless there is any question about the immunologic competence of the dog to be vaccinated and the dog is an adult. (vin.com)
