PUREVAX Feline 3 contains a lyophilized suspension of modified live feline rhinotracheitis, calici, and panleukopenia viruses, each propagated in a stable cell line, plus sterile water diluent. Safety and immunogenicity of this product have been demonstrated by vaccination and challenge tests in susceptible cats.

For primary vaccination, revaccinate with a second 1 mL dose 3 to 4 weeks later. Cats younger than 12 weeks of age should be revaccinated with a single 1 mL dose every 3 to 4 weeks, the last dose given at or over 12 weeks of age. Revaccinate annually with a single 1 mL dose.
