Why is DAPP repeated several times?
Why do Canines receive their core vaccines throughout their life?
People do not receive their core vaccines, every few years and we far out live dog.....
Let's talk about Puppies first:
In a canines (humans also) a mothers milk provides natural immune protection, antibodies to fight off infection.
Studies have shown that this immune protection can weaken if not totally kill off the vaccines given.
This all depends on how long it’s been since the pup has been weened, because this protection diminishes, in a slow arc of decline, over time.
The veterinary protocol has been to keep vaccinating and re-vaccinating, since the arc of decline in mothers milk immunity – varies depending on many factors.
