Pet's info: Cat | British Shorthair | Male | neutered | 11 months and 29 days old
Hello, I have a cat born with cat flu but no physical symptoms (carrier). Would I be able to get him the vaccination injections? And would I be able to get another cat as his brother recently passed? Thank you

I'm assuming that your cat has an upper respiratory virus like herpesvirus or calicivirus. It is fine to vaccinate cats who have been already infected, especially since this is typically a combination vaccine that covers other viruses as well. There is some evidence that the intranasal vaccine could lessen the severity of signs in a cat who is having an outbreak, but if your cat is already infected the vaccine will not cure him. If you introduced another cat and Frank became symptomatic again (i.e. sneezing, watery eyes or nasal discharge) the new cat could catch the disease. That being said, these viruses are extremely common and many kittens have been exposed even before they are vaccinated. If you are concerned you could always consider adopting an older cat who already has been vaccinated.
