New Principles of Immunology:
All 27 veterinary schools in North America are in the process of changing
their protocols for vaccinating dogs, based on current research leading to
the development of new principles of immunology.
A dog's immune system matures fully by age 6 months. If a modified live
virus vaccine is given after 6 months of age, it produces immunity which
should be good for the life of the dog. If another modified live virus
vaccine is given a year later, the antibodies from the first vaccine
neutralize the antigens of the second vaccine and there is little or no
Annual boosters for Parvo and Distemper are now
considered unnecessary and subject the dog to potential risks of allergic
reactions and such diseases as immune-mediated hemolytic anemia. There is no
scientific documentation to back up label claims for annual administration
of modified live virus vaccines.
Puppies receive antibodies through their mother's milk. This natural
protection can last 8 to 14 weeks. Puppies should NOT be vaccinated at
younger than 9 weeks, because maternal immunity will neutralize the vaccine
and little protection (0 - 38%) will be produced. Vaccination at 6 weeks
will, however, DELAY the timing of the first highly effective vaccine.
Vaccinations given 2 weeks apart actually SUPPRESS, rather than stimulate,
the immune system. Vaccinations should be given beginning at 9 weeks of age
(or later if the pup is till nursing), then every 3 to 4 weeks apart up to
about 16 weeks of age. Another vaccination given sometime after 6 months of
age (usually at 16 months) should provide lifetime immunity.
Remember that an educated and informed decision needs to be made when
considering the risks versus the benefits of vaccinating your pets.
Note: Rabies vaccines must be given according to State Law. IMPS also has
all dogs Heartworm tested prior to adoption.
