My question is: While I see the logic of the immune system defeating the vaccine, is it true that the 1st round for her was basically worthless? I don't know if I should feel like the new vet just wanted to make some money off of our visit because we are using a low-cost spay certificate for the surgery or if the old vet took our money for an unnecessary round of vaccs.
No, that first round was not worthless. If I waited any longer than six weeks to give my pups their first (in a series of three) vaccinations I'd have some very sick and/or dead puppies on my hands (as well as conscience). Mom's antibodies work well for about five to six weeks. After the sixth week, protection from maternal antibodies start to wane. Sometimes the protection may last a little longer, sometimes, for whatever reason, it starts to wane before six weeks. There is a range of variability in which the duration of protectin offered. If I waited until the eight week to start the vaccinations, and a pup's maternal antibodies were beginning to wane at six weeks, that would allow a "window of opportunity" for Parvo to strike. By the seventh week, the antibodies may be too low to offer adequate protection, thus allowing that "window" of vulnerability to exist for a week and put the pup(s) in serious danger. Parvo is pandemic. It's not to be messed with or taken lightly. Even if your particular pup's
maternal antibodies were still active and able to counteract the vaccine, your pup's sibling may not be so fortunate.... Again, jmho here, but vaccinating at six weeks, while it may not be necessary for all
pups, is certainly necessary for some
pups. Better to offer protection to all the pups (and have some overridden by maternal antibodies) than to not offer it to any and allow Parvo to strike those whose maternal antibodies faded early (and who would have been protected had they recieved the first vaccine at six weeks).
I personally vaccinate at six weeks, nine weeks, and twelve weeks with a high-titer vaccine put out by Pfizer. Anything less than a high titer vaccine is not adequate enough protection for where I live
Just my two cents worth. Hope it helps a little.
