Who came up with the idea that we need to jab our animals yearly?. A marketing arm for pharmaceutical of course.
Taking medical advice from people who sell you the medicine, never works out well for the jab ee.
2010: The international veterinary community is now increasingly supports the position that annual re-vaccination with core vaccines is not required on a life-long basis,”
Intervet's own study:
A challenge-of-immunity study was conducted to demonstrate immunity in dogs 3 years after their second vaccination with a new multivalent, modified-live vaccine containing canine adenovirus type 2 (CAV-2), canine parvovirus (CPV), and canine distemper virus (CDV). Twenty-three seronegative pups were vaccinated at 7 and 11 weeks of age. Eighteen seronegative pups, randomized into groups of six dogs, served as challenge controls. Dogs were kept in strict isolation for 3 years following the vaccination and then challenged sequentially with virulent canine adenovirus type 1 (CAV-1), CPV, and CDV. For each viral challenge, a separate group of six control dogs was also challenged. Clinical signs of CAV-1, CPV, and CDV infections were prevented in 100% of vaccinated dogs, demonstrating that the multivalent, modified-live test vaccine provided protection against virulent CAV-1, CPV, and CDV challenge in dogs 7 weeks of age or older for a minimum of 3 years following second vaccination.
The WSAVA guidelines specifically advise that dogs properly vaccinated with MLV core CDV, CPV-2 and CAV-2 vaccines (distemper, parvovirus and adenovirus) “would have ≥98% protection from disease”. They recommend that dogs should not be vaccinated more frequently than every three years, and that immunity to viral disease lasts for at least seven years, but probably for life. This is based on direct challenge studies, and on serology. They call for annual checkups and possibly titer tests to replace revaccination each year.
The 2003 American Animal Hospital Association canine vaccine guidelines state that “there is no scientific basis for the recommendation to revaccinate dogs annually with many of the current vaccines that provide years of immunity.”
The 2003 AAHA guidelines state:
“When MLV vaccines are used to immunize a dog, memory cells develop and likely persist for the life of the animal. Resident memory cells respond rapidly providing an anamnestic immune response at the time of challenge (infection) with the pathogen.”
The WSAVA guidelines also note: “Most vaccinated dogs will have a persistence of serum antibody (against core vaccine antigens) for many years. For core vaccines there is excellent correlation between the presence of antibody and protective immunity and there is long DOI (duration of immunity) for these products.”
What's the debate?
