As many people are aware - we do NOT support the Felv vaccine and in fact, have it in our contract that if you choose to vaccinate with it, you are not covered by us. You initial to this effect and understanding.
And here is why - Felv vaccination causes such severe immunosuppresion through a very specific envelope protein as to permit virus mutation/propogation. And what virus mutates most frequently - Cancer and FIP ! the 2 most deadly disease's in cats.
Here is the original document.
This article produced in 2014 again proves the immunosuppressive levels of the Felv vaccine.
Even Pet Web MD claims that -"" Vaccination with FeLV or rabies vaccine appears the be the underlying
cause of this type of sarcoma
. In fact, risk of sarcoma formation
following a single injectable vaccination in the neck-shoulder region is
50 percent higher than for cats not receiving a vaccination. Moreover,
the risk of developing the tumors may increase with the frequency and
number of vaccinations given. In one study, cats given two vaccinations
at the same site is 127 percent more likely to develop tumors than those
not receiving vaccinations, and those with three or four vaccines at
the same site were more than one and a half more likely (175 percent
higher).""

In this case a best defense is a great offense - always Felv/Fiv test any new cat coming into the home before they come into contact with your current kitties. Make sure your current kitties have been tested and are Negative - if you dont know their status , FIND OUT.
Keeping your kitty indoors only , parasite free and with minimal contact with unknown animals is the best defense once you are an Felv/FIV negative house.
