Don’t Vaccinate Your Adult Cat for Distemper

Seriously? Yes! Evidence is mounting that the common FVRCP (feline viral rhinotracheitis, calicivirus and paneleukopenia) vaccine may cause long-term damage to cats’ kidneys that increases with every booster. Here’s the report from Colorado State University:

The Center for Companion Animal Studies at Colorado State University has shown that cats vaccinated with FVRCP vaccines grown on Crandell-Rees Feline Kidney (CRFK) cell lines can develop antibodies to renal proteins, and that cats hypersensitized to CRFK cell lysates can develop interstitial nephritis…Cats administered FVRCP vaccines parenterally (by injection) have higher levels of circulating antibodies to these antigens than do cats who were administered a FVRCP vaccine for intranasal administration.

Similar antibodies have been implicated in the development of renal disease in humans, and there is every reason to suspect that they do the same in cats. Chronic renal failure (CRF), also called chronic kidney disease (CKD) in cats is known to be caused by chronic interstitial nephritis, or inflammation of kidney tissue–the very thing that these vaccines cause.

Panleukopenia is a deadly disease, and kittens must receive their initial vaccine series. Totally unvaccinated cats may be at risk. (See link below) However, adult cats who were adequately vaccinated as kittens do not need repeated boosters.
