It is important to realize that certain conditions and events may cause some cats to be unable to develop or maintain an adequate immune response following vaccination. Prior exposure to the disease, or disease latency, are conditions in which vaccination will not alter the course of the disease. Therefore, diagnostic testing of all cats for FeLV antigen prior to vaccination is recommended. Also, vaccination with this product will not offer cross-protection against feline immunodeficiency (FIV), another feline retrovirus. It is important to advise the cat owner of these situations prior to vaccination. For additional product information, please see clickable links listed under Downloadable Resources to the right .
