Unfortunately, this may not be true. The FIV vaccine does not contain all strains of FIV, and not all cats are 100% protected after receiving it, even against those strains it contains. It's also only been proven to last a year, so unless you decide to give it to your kitty annually, efficacy is unknown past the mandated FDA approval time. I know it's too late now for your other kitty, but it's definitely something to consider if you get another cat in the future. To me, it's a worthless vaccine and I wouldn't give it, but that's between you and your veterinarian and what makes you most comfortable. I was taught never to give it - I don't even carry it in my clinic. We've got at least 2 confirmed FIV kitties who live (and thus run loose) where I work and despite as much fighting as can happen between all our clinic cats, no one has popped up with FIV since coming to live with us.

Anyway, I just believe in the power of having all the information. Not everyone in my profession is as good as overloading their clients with every nuance as I am, haha. I'm still learning that fine line between too much and too little, but here on the internet you can at least review the information as needed in small doses.

HTH.
