I just recently changed the brand of puppy shots that I used, at the advice of a representative from Revival Animal Health, where I have ordered all my vaccines for the past 11 years. The vaccines were on sale, so she advised they were very good and would save me some money. I vaccinated 8 puppies with the new Solo Jec 5 Plus, manufactured by Boehringer-Ingelheim Vetmedica, Inc. , all of which developed parvo and died. Then it spread to 7 more puppies that were too young to vaccinate, and I lost them as well. My vet tested with the Idexx Snap Parvo test and it was positive for parvo. I had other puppies that were vaccinated with another vaccine, that are fine and did not develop parvo, so I know it was this particular vaccine. The company that I ordered from (Revival Animal Health) denies having any knowledge of this particular vaccine causing problems for anyone else, and were just plain nasty to me when I called them for a refund after they received the remaining product back. I don't know if we're supposed to use name brands or company names on a site like this, but I certainly don't want anyone else to have to go through the nightmare that I have been through for the last three weeks doctoring sick puppies. I have probably lost over $15,000 in puppies and veterinary care alone. I have kept 4 of the vaccines, so if there is anyone out there that knows where I can get these tested, to prove that they are what caused the parvo, I would greatly appreciate hearing from you.
