                 DOG  VACCINATION PROTOCOLS & SERVICES

                                  A Review by Dr. Michael W. Fox

“Anytime you inject anything into a patient you have the potential of killing them”.—Prof. Ron Schultz, DVM.

The practice of giving dogs several different vaccinations against various diseases all at the same time early in life and then again every year as "boosters" for the rest of their lives is coming to a close. This is for two primary reasons: animals can have adverse reactions to vaccinations that can impair their health for the rest of their lives; routine "booster" shots are not needed since earlier vaccinations have given animals sufficient immunity to the diseases in question.

First, puppies should not be given vaccinations before 8-10 weeks of age since this can interfere with the natural immunity in their systems conferred by the colostrum or first milk of their mothers. But if the immune status of the mother is unknown, as is the situation for many to-be-adopted pups in animal shelters, vaccinations at an earlier age between 5-6 weeks is the usual protocol. Adult animals in a compromised immune state, as for example those who are ill, injured, or being given an anesthetic and operated on, such as being spayed or castrated, or for any other surgical procedure, are pregnant or nursing, or are old and infirm, should not be vaccinated.

Rabies vaccinations, unless in-field conditions make this logistically difficult, should never be given at the same time other combined vaccinations are given. Separate by at least 3 weeks.

For minimal basic vaccination  protocols, developed by Dr. Jean Dodds, see Table 1.

Studies have shown that in normal, healthy dogs at the time of vaccination, Parvovirus vaccines are good for 7 years, Rabies vaccines for 3-7 years, Distemper vaccines for 5-15 years (depending on the strain), and Adenovirus 2 vaccines for 7-9 years. Prof. Ron Schultz recommends using Merial’s 3-way combo; parvo, distemper and CAV2/hepatitis as the only relatively safe combination of vaccines.

 If your dog received all core vaccines by 16 weeks of age, have antibody blood titers evaluated at 1 year of age if you have reservations about re-vaccination.

Corona virus and giardia vaccinations for dogs are not recommended.

For dogs at risk, Leptospirosis vaccine (the four-serovar product of Fort Dodge being preferred) should be given at 12 and 15 weeks and repeated one year later. It only confers protection, however, for 3-4 months, so repeated vaccinations are called for with dogs with significant exposure risk.

 Lyme vaccine should be given to at-risk dogs but the bacterium vaccine can cause immune-complex disease so Merial’s recombinant Lyme vaccine is preferred. Again, blood serum titers should be taken to assess dog's immune status where there is doubt, rather than simply giving booster shots.

Neither Lyme disease vaccinations, that give highly unreliable protection, nor leptospirosis vaccinations should be given close to the time that any other vaccinations are given.

No vaccine can guarantee immunity, since different strains of infective agents may be involved, and animals who are stressed, suffering from poor nutrition, genetic susceptibility and concurrent disease may have impaired immune systems and lowered resistance to disease. But this does not mean that they should never be vaccinated or be routinely re-vaccinated just in case, because vaccinations can cause further immune system impairment and a host of health problems---the so called vaccinosis diseases--- that these new vaccination protocols are aimed at minimizing.

Article Abstract

OBJECTIVE: To determine whether client-owned dogs in Australia, last vaccinated with Canvac() vaccines containing canine parvovirus-type 2 (CPV-2), canine distemper virus (CDV), canine adenovirus type 2 (CAV-2) canine parainfluenza virus (CPiV) at least 18 months ago, were seropositive or responded serologically to revaccination. METHODS: A total of 235 dogs were recruited from 23 veterinary clinics, representing a variety of breeds, ages and time since last vaccination (TSLV: range 1.5-9 years, mean 2.8 years). Dogs had a blood sample taken and were revaccinated on day 0. A second blood sample was taken 7-14 days later. Blood samples were assessed for antibody titres to CPV-2 (by haemagglutination inhibition) and CDV, CAV type 1 (CAV-1) and CPiV (by virus neutralisation). Dogs with a day 0 titre >10 or a four-fold increase in titre following revaccination were considered to be serological responders. RESULTS: The overall percentage of dogs classified as serological responders was 98.7% for CPV-2, 96.6% for CDV, 99.6% for CAV-1 and 90.3% for CPiV. CONCLUSIONS: These results suggest that the duration of serological response induced by modified-live vaccines against CPV-2, CDV, CAV-1 and CPiV, including Canvac() vaccines, is beyond 18 months and may extend up to 9 years. Accordingly, these vaccines may be considered for use in extended revaccination interval protocols as recommended by current canine vaccine guidelines.

 

****************************************************

Veterinarians in the U.K are being urged to adopt the vaccinations of cats and dogs against “core” diseases (excluding rabies) advocated by the World Small Animal Veterinary Association to its 86 member countries.* They are similar to those that I and other veterinarians in the U.S. and Canada have been advocating for the past 15 years and more on the basis of sound science---advances in vaccinology, immunology and blood titer testing rather than personal opinion, to optimize the benefits and minimize the risks.

The core vaccinations against canine distemper virus, canine adenovirus and canine parvovirus type 2 are all given to pups at 6, 12,16 weeks or older, and 26 weeks of age and at 52 weeks of age if not given at 26 weeks. Then not until 4, then 7 and then 10 years of age with the option of serum testing and then not re-vaccinating if antibody titers show good immunity.

In sum, these core vaccinations need not be given annually. Other vaccinations (non-core) may be called for depending on the region, outbreaks of infections and associated exposure risks.

OUR ANIMAL RELATIONSHIPS: THE MOMENTS OF TRUTH PROJECT
Dr. Michael W. Fox

What right do we humans have to exploit other animals?  Where does that right come from and what are the limits if any?  What duties or obligations do we have in our relationships with our dogs, cats and other animals domesticated and wild?

          Follow and support Caroline Kraus and her Moments of Truth Project documentary film as she travels across the U.S. asking people, who variously live, work with and care for animals, these and other relevant questions.

Is there an overriding consensus and what are the reasons why people respond very differently to these questions, which in part examine our character, culture and future?

The viewing and discussion of this kind of documentary should be part of every school curriculum and will be of interest to all who work with, profit from and care for animals.
