The Three-Year (Triennial) Vaccination and Its Impact on Public Health

Dr. Kevin Reily is quoted as saying, "It is clear from both controlled laboratory challenged studies and more than 20 years of field experience with the triennial (every three years vaccination) rabies programs, that the three year rabies vaccines are extremely effective."

Reily, a vet for (public health officer in charge of rabies control), the state of California, where the risk of rabies is much higher having both bat and skunk rabies and ten million dogs and cats at risk, has used the triennial vaccination program in dogs and cats for the last 20 years. No currently vaccinated dogs or cats have developed rabies during the two decades. In addition, that no animal received just two rabies vaccines in its lifetime, regardless of current rabies vaccine status, developed rabies in the state of California during the last 20 years!"

"Even Rabies vaccine is probably good for more than 3 years, since it is a viral vaccine. The tests done by the vaccine manufacturers on the required 7 dogs were carried out only at three years post-vaccine. If they had tested dogs longer post-vaccine, rabies [vaccine] may be good for life."
