PostSubject: Puppy Vaccines   Wed Nov 18, 2009 6:10 pm

Protection from the mother (maternal antibodies)

A newborn puppy is not naturally immune to diseases. However, it does have some antibody protection which is derived from its mother's blood via the placenta. The next level of immunity is from antibodies derived from the first milk. This is the milk produced from the time of birth and continuing for 36-48 hours. This antibody-rich milk is called colostrum. The puppy does not continue to receive antibodies through its mother's milk. It only receives antibodies until it is two days of age. All antibodies derived from the mother, either via her blood or colostrum are called maternal antibodies. It must be noted that the puppy will only receive antibodies against diseases for which the mother had been recently vaccinated against or exposed to. As an example, a mother that had NOT been vaccinated against or exposed to parvovirus, would not have any antibodies against parvovirus to pass along to her puppies. The puppies then would be susceptible to developing a parvovirus infection.

Window of susceptibility

The age at which puppies can effectively be immunized (protected) is proportional to the amount of antibodies the puppy received from its mother. High levels of maternal antibodies present in the puppies' bloodstream will block the effectiveness of a vaccine. When the maternal antibodies drop to a low enough level in the puppy, immunization by a commercial vaccine will work.

The antibodies from the mother generally circulate in the newborn's blood for a number of weeks. There is a period of time from several days to several weeks in which the maternal antibodies are too low to provide protection against the disease, but too high to allow a vaccine to work. This period is called the window of susceptibility. This is the time when despite being vaccinated, a puppy or kitten can still contract the disease.

Disease prevention in puppies is extremely important i think. It's good to help them prevent illnesses in case they are exposed. Definitely worth getting vaccinated so your pup doesnt pick something up at the dog park or elsewhere.
