Not sure about reaction percentages, but info about this CD Vaccine is being shared widely. Have you seen any actual studies on this vaccine (Neovac-D)? I've heard claims that it is safe for kits, but nothing about any broader studies. I would also love to read about a controlled study that proved its effectiveness. I know other vaccines have been abandoned because they were effective in other animals, but not in ferrets. Lack of reactions doesn't mean much unless we know it's protecting ferrets. I've also never heard of a vaccine that didn't need a baseline series to establish immunity. Kevin Farlee [Posted in FML 7310]
