Why do puppies and kittens need so many vaccinations?

FAQ Question: 
Why do puppies and kittens need so many vaccinations?
FAQ Answer: 

When your pet gets a vaccine, its immune system produces antibodies in response. Nursing puppies and kittens receive certain antibodies from their mothers that help protect them from disease early in life. These same antibodies, passed in the mother's milk, can keep vaccines administered to young animals from being completely effective. The presence of maternal antibodies gradually decreases as the young animals age. A series of vaccines over the same period of time properly stimulates the young animal to produce its own antibodies.
