Vaccine Adverse Events

By Dr. Andrew Jones

They make the statement that:

‘Vaccine AEs (Adverse Events) are underreported in veterinary medicine.’

Meaning there are far more side effects than what is ‘published’ as they are NOT reported.

Here is some of what they have to say about side effects

Vaccines are biologic products and, as such, provoke a series of complex immune reactions that may culminate in rapid-onset side effects lasting from a few hours to a few days. Rarely do these selflimiting side effects escalate into serious AEs (SAEs).

For this reason, veterinarians are encouraged to inform clientele that their pet, regardless of breed or size, may manifest transient side effects for up to 2, and possibly 3, days after administration of any vaccine or any combination of vaccines.

Side effects commonly observed include:

reduced or loss of appetite (lasting for one or two feedings),pain at the injection site, lethargy (lack of activity), reluctance to walk and/or run, and mild fever.

Treatment is usually not indicated; however, some veterinarians have reported administering short-term symptomatic treatment (e.g., a nonsteroidal anti-inflammatory drug [NSAIDs]).

It is recommended that clientele be advised to contact the practice in the event any physical and/or behavioral manifestations progressively worsen or continue beyond 2,3 days. Clientele should be advised to contact the practice at any time if signs of systemic illness, such as vomiting, diarrhea, seizures, facial swelling, collapse, or difficulty breathing, develop.

Serious Side Effects

Injection-site reactions: lumps (abscess, granuloma, seroma), pain, swelling, hair loss associated with ischemic vasculitis

Transient postvaccinal nonspecific illness: lethargy, anorexia, fever, regional lymphadenomegaly, soreness, abortion, encephalitis,polyneuritis, arthritis, seizures, behavioral changes, hairloss or color change at the injection site, respiratory disease

Allergic (hypersensitivity) and immune-mediated reactions:

Type 1 (acute anaphylaxis): angioedema (especially the head), anaphylaxis (shock), and death

Type 2 (cytolytic): immune-mediated hemolytic anemia,immune-mediated thrombocytopenia (suspected only;causality
has not been confirmed)

Type 3 (immune-complex): cutaneous ischemic vasculopathy associated with rabies vaccine, corneal edema (blue-eye)   associated with CAV-1 vaccine, immune-mediated disease

Tumorigenesis: vaccine-associated sarcoma or other tumors

Multisystemic infectious/inflammatory disorder of young Weimaraner dogs: may be genetically linked to both a poorly
characterized immunodeficiency and to autoimmune disorders (e.g., hypothyroidism and hypertrophic osteodystrophy [HOD] that are detected shortly after vaccination

Vaccine-induced immunosuppression: associated with first or second dose of combination MLV vaccines containing CDVand
CAV-1 or CAV-2 with or without other vaccines (e.g., CPV-2, CPI). Immunosuppression begins 3 days after vaccination and persists for 7,10 days. The suppression may be associated with increased susceptibility to other diseases.

Reactions caused by the incorrect or inappropriate administration of vaccine: fatalities have been reported after subcutaneous administration of an avirulent-live Bb bacterin (intended for IN administration); inadvertent or intentional administration of vaccine by the intravenous route

Reactions associated with residual virulence attenuated vaccine: postvaccinal sneezing associated with IN administration of attenuated vaccine (e.g., Bb 1 parainfluenza virus)

Vaccine-induced interference with diagnostic tests: falsepositive polymerase chaine reaction (PCR) test results for parvovirus antigen in feces in dogs recently receiving a MLV parvovirus vaccine. Not an adverse reaction.

Reversion of vaccine virus to a virulent pathogen: generally considered rare to nonexistent among currently licensed canine vaccines when vaccines are used in the species for which they were licensed. This can become a significant problem when vaccine is used in the wild and/or exotic animals.

P.S. So just HOW common are vaccine reactions?

Good question, but as the side effects are under-reported, we just don’t know. No question FAR more common than what the reps of Big Pharma would tell you.

Which means you’ve got to really weigh the pros and cons of the vaccine.

ONLY give what is necessary.

Give it as infrequent as possible.

If you have a small dog or cat, I would ask your veterinarian about vaccine volume. WHY is it that a 160lb Great Dane would get the SAME volume of vaccine as a 3lb Chihuahua?

Makes no sense to me.

But in the AAHA Guidelines they advise to give the SAME volume, regardless of weight.

More reasons for YOU to be especially cautious.

My supplement contains specific immune supportive ingredients.

Ultimately the point of vaccines are to PREVENT disease.

There are MANY ways to do this.

Such as the use of neutraceuticals to boost and support your dog’s immune system.
