• Vaccine Name: Feline infectiors peritonitis serum vaccine
• Target Pathogen: Feline infectious peritonitis virus
• Target Disease: Feline infectious peritonitis (FIP)
• Type: Serum contianing ant-FIPV.
• Status: Research
• Host Species for Licensed Use: Cat
• Antigen: FIPV (Weiss and Scott, 1981)
• Preparation: A healthy 5-month-old kitten with an F1PV serum antibody titer greater than 1:1600 served as the immune serum donor. This animal was an SPF kitten who had seroconverted by natural exposure to FIPV-shedding contact cats and had remained asymptomatic.(Weiss and Scott, 1981)
• Immunization Route: Intravenous injection (i.v.)
• Description: A serum containing anti-FIBV produced by an asymptomatic cat was injected into other cats.(Weiss and Scott, 1981)

Cat Response

• Vaccination Protocol: Serum was administered by slow intravenous injection and given at a dosage of 11 ml/kg per cat.(Weiss and Scott, 1981)
• Challenge Protocol: Six hr after administration of serum, the experimental kittens were inoculated intraperitoneally with 0.5 ml of FIPV- infected liver homogenate.
• Efficacy: Not protected, higher fatality rate than unvaccinated cats. (Weiss and Scott, 1981)
