I've been on the list a long time and I don't remember anyone who had someone
they knew was negative, and was vaccinated, turn positive.
Now it has happened that the initial test was negative and they turned up
positive later, but I believe it was because they had been exposed and the
virus was not yet in the system long enough for a positive test. (Like animals
testing negative right out of an animal shelter. Those animals should be
retested later to be sure they were really negative after being in that
situation.)

actually, I think someone on this list had one who was vaccinated but
turned positive. And I am pretty sure that the shelter where my cats came from,
at which some of the positives live with negative ferals who are vaccinated, a
few of the ferals have turned positive over the years.

while the vaccine is said to be only 85% effective, no one that we can find
can show a documented case of a truly negative, vaccinated cat ever contracting
FeLV from living closely with a positive. which makes sense, since they say
that up to 70% of healthy ADULT cats who are not vaccinated can be exposed and
throw the virus off. so some of us question that 85% rate, and wonder if it's
not across all populations, including the high-risk ones.
