REPORT ON RABIES VACCINE
ADVERSE REACTIONS IN DOGS
The Journal of the American Veterinary Medical Association
has just published a report in its April 1, 2008 issue, Vol. 232,
No. 7, entitled:
“Postmarketing Surveillance of Rabies Vaccines for Dogs
to Evaluate Safety and Efficacy."
Despite the extreme under-reporting of vaccinal adverse reactions,
this report states on the second page that between April 1, 2004
and March 31, 2007, the Center for Veterinary Biologics,
"nearly 10,000 adverse event reports (all animal species) were
received by manufacturers of rabies vaccines..........Approximately
65% of the manufacturer's reports, involved dogs.”
The report further states on the second page that: "Rabies vaccines
are the most common group of biological products identified in
adverse event reports received by the CVB," and they give the
following description of the adverse reaction followed by the % of
dogs affected: Vomiting-28.1%, Facial Swelling-26.3%, Injection Site
Swelling or Lump-19.4%, Lethargy-12%, Urticaria-10.1%, Circulatory
shock-8.3%, Injection site pain-7.4%, Pruritus-7.4%, Injection site
alopecia or hair loss-6.9%, Death-5.5%, Lack of Consciousness-5.5,
Diarrhea-4.6%, Hypersensitivity (not specified)-4.6%, Fever-4.1%,
Anaphylaxis-2.8%, Ataxia-2.8%, Lameness-2.8%, General signs of
pain-2.3%, Hyperactivity-2.3%, Injection site scab or crust-2.3%,
Muscle tremor-2.3%, Tachycardia-2.3%, and Thrombocytopenia-2.3%.
Veterinarians are not required by law to report
adverse reactions to vaccines, to which the
World Small Animal Veterinary Association stated in their 2007
Vaccine Guidelines that there is: "gross under-reporting of
vaccine-associated adverse events which impedes knowledge of the
ongoing safety of these products."
And in an article entitled, A New Approach to Reporting
Medication and Device Adverse Effects and Product Problems, (JAMA
- June 2, 1993. Vol.269, No.21. p.2785) Dr. David Kessler,
former head of the Food & Drug Administration, reported that
"only about 1% of serious events are reported to the FDA."
In light of the 10,000 adverse reactions to the rabies vaccine in
the JAVMA report, 65% of which were in dogs, the estimated 1%
reporting of "serious" events by the former head of the FDA means
that the actual number of dogs that had adverse reactions to the
vaccine would be more like 650,000!!!!!
