Understanding Puppy Vaccinations
Vaccinations help “program” the specialize cells of the puppy’s immune system to act like smart missiles to seek and destroy problems before they cause disease. Once programmed, these cells recognize, find, and destroy viruses, bacteria or other pathogens both in the bloodstream or at the cellular level—in the nose or eyes—before they cause disease.
A puppy’s immune system won’t be mature enough to protect itself until she’s about eight weeks old. Passive immunity fills this gap when the puppies nurse from the vaccinated mom-dog’s milk. This antibody rich “first milk” is called colostrum, and protects against viruses that might threaten the puppy’s health.
However, the antibodies in mom’s milk also neutralize most vaccinations. The exceptions are some newer vaccinations made with recombinant DNA technology such as the Recombinant Distemper Vaccination. But in general, puppy shots won’t be protective until Junior’s own immune system matures enough to take over. That’s why a series of boosters are recommended during the period when Mom’s protection fades while Junior’s matures.
