Hemopet’s Hemolife Diagnostics is world renowned for its titer testing. What differentiates Hemopet is that the results of each sample are reviewed and reported by the Hemolife staff on our unique Cloud-Based computer technology Laboratory Information System (LIS). They are then personally reviewed and interpreted by W. Jean Dodds and two trained veterinary colleagues, Drs. Andrew Zuckerman and Gary Richter. Based on pet’s species, age and species, Hemopet will will provide you with suggestions if the pet should receive a booster shot.

Note about Canine Titer Testing
W. Jean Dodds suggests that dogs should be titer tested for distemper and parvovirus every three years to ensure immunity is maintained against these viruses. If a dog had been recently vaccinated with the DPV (distemper, parvovirus vaccine) shot, she suggests waiting three weeks to perform the test. Puppies, too, should be measured at least three weeks after the last vaccination and not before 16 weeks of age.
VACCINES & TITER OPTIONS
- Only ~40% of veterinarians follow the current WSAVA, AVMA, AAHA, CVMA vaccine guidelines
- They can offer separated vaccine components, rather than give them all together, since the published data show more adverse reactions when multiple vaccines are given
- Rabies vaccine is often given with other boosters for convenience, when this is ill advised, as Killed, inactivated vaccines like rabies make up 15% of veterinary biologicals used, but 85% of the post-vaccination reactions. Use only thimerosal (mercury) – free rabies vaccines
- There is no such thing as an ‘up to date’ or ‘due’ vaccination
- The immune system mounts a faster more powerful anamnestic response when encountering the same antigen again – e.g. with viral exposures and vaccines
- The immune system capacity for memory generates immunity through vaccines, but can also trigger adverse events like autoimmune disorders and allergies/hypersensitivity
- Vaccination may not equate to immunization
- But, vaccinated and truly immunized animals should be fully protected from disease; Immune memory cell immunity should persist life long
- Giving boosters to immunized animals is unwise, as it introduces unnecessary antigen, adjuvant and preservatives
- AAHA 2003 – Current knowledge supports the statement that “No vaccine is always safe, no vaccine is always protective and no vaccine is always indicated”
- Vaccine non-responders = genetic trait; do not breed them
- Heavy metal exposure from vaccines is an emerging concern for humans, pets and livestock
- Half-dose CDV + CPV vaccines in small adult dogs sustained protective serum antibody titers
- Other vaccines including hepatitis are optional, depending on lifestyle and local disease risk
- Three or more days after the last round of puppy vaccines, pups can be out and about to be socialized. Between 10-14 weeks of age, socialization can take place in the back yard or at puppy training classes with known friends and healthy dogs
- Kennel cough vaccines not 100% effective; are they needed?
- Oral/Intranasal Bordetella releases interferon, which inhibits respiratory viruses (adenovirus-2, (parainfluenza, influenza) and hepatitis; the injectable version does not cross-protect
- Canine Influenza produces fever whereas kennel cough does not. Is the bivalent vaccine needed, when only mild clinical signs usually arise?
- Avoid Vaccination
- Period just before estrus (30 days)
- During estrus
- No evidence that annual boosters are necessary; need to lengthen the interval to every 3 yrs
- Geriatric animals vaccinated only with caution
- Monitor serum antibody titers instead every 3 years for immunized pets.
- Any measurable antibody level indicates protection
FAQs: VACCINE ISSUES
Q. What are the “core” vaccines for dogs?
A. Canine distemper virus (CDV), canine parvovirus (CPV-2), canine adenovirus (hepatitis) virus (CAV), and canine rabies virus.
Q. What are the “core” vaccines for cats?
A. Feline panleukopenia virus (FPV), feline herpes virus (FHV-1), feline rhinotracheitis (calici) virus (FCV), feline rabies virus, and FeLV for cats below 1 year of age.
Q. Is there risk of overvaccinating with vaccines not needed for a specific animal?
A. Yes. Vaccines contain material designed to challenge the immune system of the pet, and so can cause adverse reactions. They should never be given needlessly, and should be tailored to the pet’s individual need, health status, geographical location risk, and lifestyle. Vaccination is truly a “balancing act” that should match the needs of the animal.
Q.Are the initial series of puppy core vaccines immunosuppressive?
A. Yes. This period of immunosuppression from modified live virus (MLV) canine distemper, parvovirus and hepatitis vaccines coincides with the time of vaccine-induced viremia, from days 3 to 10 after vaccination.
Q. Can smaller doses of vaccines be given to toy dog breeds?
A.Yes, they can, although some vaccinologists believe that the whole amount should be given because it represents the minimum immunizing dose. My view is that a half dose of vaccines, other than rabies, as required by law, should suffice and would be safer, based upon our published study (JAHVMA, 2015;41:12-21).
Q. Can anesthetized patients be vaccinated?A. This is not preferred, because a hypersensitivity reaction with vomiting and aspiration could occur and anesthetic agents can be immunomodulating.
Q.Is it safe to vaccinate pregnant pets?
A. Absolutely not.
Q. Should pets with immunosuppressive diseases such as cancer or autoimmune diseases, or adverse vaccine reactions/ hypersensitivity receive booster vaccination?
A. No. Vaccination with MLV products should be avoided as the vaccine virus may cause disease; vaccination with killed products may aggravate the immune-mediated disease or be ineffective. For rabies boosters, local authorities may accept titers or a deferment instead.
Q. If an animal receives immunosuppressive therapy, how long afterwards can the pet safely be vaccinated?
A. Wait at least 2 weeks.
Q. Should vaccines be given more often than 2 weeks apart even if a different vaccine is being given?
A. No. The safest and most effective interval for immunization is 3-4 weeks apart.
Q. At what age should the initial vaccine be given in the puppy and kitten series?
A. Not before 6 weeks and preferably at 8-10 weeks in puppies. Not before 4 weeks and preferably at 6 weeks in kittens.
Q. At what age should the last vaccine dose be given in the puppy and kitten series?
A. The last dose of vaccine should be given between 14-18 weeks of age in dogs, and 16-20 weeks of age in cats. However, newer data from cats indicates that unlike puppies, residual maternal derived antibody (MDA) levels can last as long as 20 weeks in kittens, so new recommendations are to give another kitten booster at 6 months of age, but apart from their first rabies vaccine. Rabies vaccine should preferably be given separately as late as possible under the law (e.g. 20-24 weeks).
Q. Can oral or intranasal Bordetella vaccine be given parenterally?
A. No. The vaccine can cause a severe local reaction and may even kill the pet.
Q. Will a killed parenteral Bordetella vaccine given intranasally produce immunity?
Q.Can MLV parenteral vaccines for cats be used intranasally?
A. Never. Any mucosal (e.g. conjunctival and nasal) contact with these vaccines can cause disease.
Q. Are homeopathic nosodes capable of immunizing pets?
A. No. There is no scientific documentation that nosodes protect against infectious diseases of pets. The one parvovirus nosode trial conducted years ago did not protect against challenge.
Q. Should disinfectant be used at the vaccine injection site?
A. No. Disinfectants could inactivate a MLV product.
Q. Can vaccines cause autoimmune diseases?
A. Vaccines themselves do not cause these diseases, but they can trigger autoimmune responses followed by disease in genetically predisposed animals, as can any infection, drug, or chemical / toxic exposure etc.
Q. Can a single vaccine dose provide any benefit to the dog or cat? Will it benefit the canine and feline populations?
A. Yes. One dose of a MLV canine or feline core vaccine should provide long term immunity when given to animals at or after 16 weeks of age. Every puppy and kitten 16 weeks of age or older should receive at least one dose of the MLV core vaccines. We need to vaccinate more animals in the population with core vaccines to achieve herd immunity (e.g. 70% or higher, when probably only 50% of dogs and 25% of cats are vaccinated) and thereby help prevent epidemic outbreaks.
Q. If an animal receives only the first dose of a vaccine that needs two doses to immunize, will it have immunity?
A. No. A single dose of a two-dose vaccine like Leptospirosis or feline leukemia vaccine will not provide immunity. The first dose is for priming the immune system. The second for boosting the immunity has to be given within 6 weeks; otherwise the series has to start over again. After those two doses, revaccination with a single dose can be done at any time.
Q. Can maternally derived antibodies (MDA) also block immunity to killed vaccines and prevent active immunization with MLV vaccines?
A. Yes. MDA can block certain killed vaccines, especially those that require two doses to immunize. With MLV vaccines, two doses are often recommended, particularly in young animals, to be sure one is given beyond the neutralizing period of MDA. See above new notation about MDA in kittens.
Q. How long after vaccination does an animal develop immunity that will prevent severe disease when the core vaccines are used?
A. This is dependent on the animal, the vaccine, and the disease.
∙ The fastest immunity is provided by canine distemper virus (CDV) vaccines, e.g. MLV and recombinant canarypox virus vectored. The immune response starts within mins – hrs and provides protection within a day without interference from MDA.
∙ Immunity to CPV-2 and FPV develops after 3-5 days when an effective MLV vaccine is used. In contrast, killed FPV vaccine often takes 2 – 3 wks or longer to provide protective immunity.
∙ CAV-2 MLV given parenterally provides immunity against CAV-1 in 5 to 7 days.
∙ Time from vaccination to immunity is difficult to determine for FCV and FHV-1, the upper respiratory viruses of cats, because some will not develop measurable immunity.
Q. Can dogs and cats be “non-responders” and fail to develop an immune response to vaccines?
A. Yes. This is a genetic characteristic seen particularly in some breeds or dog families. Boosting them regularly will not produce measurable circulating immunity, but they may be protected against disease by their cell-mediated and secretory immunity. There are no parallel data for cats.
Q. Are there parvovirus and distemper virus field mutants that are not adequately protected by current MLV vaccines?
A. No. All the current CPV-2 and CDV vaccines provide protection from all known viral isolates, when tested experimentally as well as in the field. The current CPV-2 and CPV-2b vaccines provide both short- and long-term protection from challenge by the CPV-2c variant.
Q. Should FeLV (feline leukemia virus) and/or FIV (feline immune deficiency virus) -positive cats be vaccinated?
A. There is no proven benefit to vaccinate retrovirus-infected pets.
Q. Is there a preferred site of vaccination?
A. For dogs, preferred sites are in between shoulder blades, and Sub-Q or IM for rabies in the rear thigh muscle. For cats, distal limbs and id-tail are preferred, but not in between shoulder blades or in front of shoulder, or thigh muscles.
Q. Are serum antibody titres useful in determining vaccine immunity?
A. Yes. They are especially useful for CDV, CPV-2 and CAV-1 in the dog, FPV in the cat, and rabies virus in the cat and dog. Rabies titers, however, are often not acceptable to exempt individual animals from mandated rabies boosters in spite of medical justification. Serum antibody titers are of limited (leptospirosis, Bordetella, Chlamydia) or no value (corona virus) for the other non-core vaccines. Feline FIP (feline infectious peritonitis) vaccine is not recommended for pet cats.
