Re: [Felvtalk] Felv vaccine and booster

2010-04-18 Thread TANYA NOE
There is no evidence of the FELV vaccine causing a cat to turn FELV positive. 
There is truth however to the FIV vaccine causing cats to test positive. That 
is why my clinic requires either tattooing or microchipping if an owner wants 
the FIV vaccine. Hope this helps.

 I have never heard this before and
 have had FELV cats since 2003, and read up on it, used to
 more than I do now.  I seriously doubt if there's any
 truth to it at all.  Perhaps they're getting mixed up
 with the FIV vaccine causing a cat to TEST positive for FIV
 (not turn positive though).

  I heard this from a friend and it shocked me because
 another friend has a healthy cat who received her felv
 vaccine and booster last year. All her pets are indoor and
 outdoor animals. She has 1 cat and two dogs.

Impossible. The virus used in the FeLV vaccine is a killed virus.  The only
vaccines that have a *remote* potential to cause disease are Modified Live
Virus vaccines.

this is an old myth that continues to make the rounds.

the FeLV virus does not, and cannot, cause a cat to become positive. in
fact, there is anecdotal evidence on this list, that vaccinating a truly
positive FeLV increases their lifespan!

(anyone on this list also on Fan-H? gloria, maybe? there was just a
discussion on the differences between the kinds of vaccines that looked
really good--i don't have the time right now to go grab all the
discussion.)

as for the FIV vaccine, it doesn't cause FIV either, it just produces
antibodies that will make the cat TEST positive on both the SNAP and Western
Blot test. bless that vet who realizes this (tho all should), and insists
upon identifying the cat's reason for a positive test!
