Helps Prevent Disease Cause By Feline Leukemia Virus (FeLV)


FELOCELL FeLV is for vaccination of healthy cats as an aid in preventing disease caused by feline leukemia virus (FeLV).

Collapse All
    • Induces anti-FOCMA (feline oncornavirus-associated cell membrane antigen) antibodies, which help provide tumor protection.1
    • Builds on the history of LEUKOCELL® 2. FELOCELL® FeLV and LEUKOCELL® 2 are the only vaccines that help protect against FOCMA.
    • Prepared by propagating FeLV subgroups A, B and C in FeLV-transformed lymphoid cells.
    • Viral antigens are inactivated, combined with Gentle Safe-Quil™ adjuvant to enhance the immune response and packaged in liquid form.
    • FELOCELL® FeLV is supported by our Petcare Immunization Support Guarantee (ISG).
    • Same master seed as LEUKOCELL® 2 from a transformed cell line.
