As long as you have the Coggins and Rabies paperwork, other vaccinations don't matter on the CVI. It's essentially an extra hoop to jump, if you know what I mean. All it says is that a vet saw your horse on such and such date, and he was healthy then. As long as your show entry asks for it, you should be able to produce it at sign-in. I know people who do the bare minimum vet requirement (only Coggins and Rabies) to show, and they still need a CVI for certain shows and events. I usually have mine given West Nile, Strangles, and what the vet calls a 4-way that includes several vaccines in one shot, in addition to the basic Coggins and rabies, and that is written on the CVI, but the presence of the notation, or lack thereof, isn't that important, as long as you have the paper. Yeah, it gets confusing, and a little wierd. I chased these papers across 2 states because the CVI requirement was implemented the year I bought my first horse. He came with a Coggins and rabies, both within date, but I needed to find his old vet to get a CVI, that I didn't know I needed until the last minute, ha ha.
