If vaccinated as a young kitten it is unlikely your cat will contract flu, as he or she will already have developed antibodies against the disease. However, if your vaccinated cat does contract flu’ the severity of the virus is drastically reduced.
If your cat is a carrier, vaccination is still recommended for two reasons:
1. Any symptoms that develop will be less severe.
2. It is extremely unlikely that your cat would be a carrier of both FVR and FCV, therefore vaccination will prevent your cat catching the other strain of flu.
Vaccinations should continue to be given by your vet once every year.
