W Jean Dodds Vaccine Protocol VACCINATION PROTOCOLS
Even after the puppies have been weaned, they will still have maternal antibodies from nursing. Those maternal antibodies attack and kill the viruses contained in the vaccines, leaving the puppy unprotected from deadly diseases. That's why it is so important that your puppy have the full round of vaccinations (usually about fourteen weeks) plus two weeks for full immunity before taking him to any places other dogs go.
