New Molecular Technology Provides Improved Potency

June 22, 2012


Duluth, Ga. – June 22, 2012 – Merial’s PUREVAX® Recombinant FeLV – the newest addition to the only complete line of non-adjuvanted feline vaccines in the U.S. - is now available. Delivered subcutaneously by needle injection, PUREVAX Recombinant FeLV features improved potency, providing excellent protection with a lower antigen concentration than PUREVAX Recombinant Leukemia Vaccine. 

Feline leukemia virus (FeLV) can lead to contagious, incurable and lethal disease.  FeLV causes cancer in about 20 percent of infected cats  and contributes to the development of other infectious diseases and anemia by suppressing the immune system and function of bone marrow.  The American Association of Feline Practitioners (AAFP) recommends FeLV vaccination for all kittens,  and an annual booster inoculation is recommended for cats considered to be at risk of exposure – which include those not housed strictly indoors.(5)

“PUREVAX Recombinant FeLV offers the convenience of subcutaneous delivery with the efficacy and safety you would expect from a non-adjuvanted recombinant vaccine,” said Dr. Robert Menardi, marketing director for Pet Vaccines, Merial. “Non-adjuvanted vaccines may help reduce the potential risks associated with adjuvants, which include injection site reaction, injection site granuloma or chronic inflammation.”(6) 


Merial developed PUREVAX Recombinant FeLV in response to customer desire for a safe, efficacious, non-adjuvanted product with convenient route of administration. PUREVAX Recombinant FeLV uses recombinant canarypox-vectored vaccine technology, which stimulates FeLV-specific cell-mediated immunity and is proven effective in the face of severe challenge.

 PUREVAX Recombinant FeLV is recommended for the vaccination of healthy cats 8 weeks or older as an aid in the prevention of disease due to feline leukemia virus. For primary vaccination, cats should receive two 1-ml dose vaccinations, three weeks apart. Annual booster injections are recommended in cats considered to be at risk of exposure. Diagnostic testing for FeLV prior to vaccination also is recommended.
