1.Dog and cat's immune system is mature fully at 6 months. If one modified live vaccine is given after 6 moths of age, it will produce life long immunity.
2.If another mod. live vaccine is given, the antibodies from the first will neutralize the antigens of the second and there is little or no effect. The titre is NOT boosted, nor are more memory cells induced.
3.Vaccinations given 2 weeks apart have been shown to supress rather than stimulate the immune system.
4.When a vaccine is administered, the organism is injected directly into body tissues, bypassing the local immune responses. When this happens, much of the immune system is rendered useless. The body then must compensate by increasing the activity of the balance of the system, and the defenses begin in a compromised state, with the organism already in the blood stream....
5. The second, and more compelling theory of the mechanism of interaction between a vaccine and the body suggests that vaccines "protect" against the acute disease not by preventing the disease but by changing the form of the disease to a chronic disease. 2 For example, the panleukopenia virus of cats induces an intense, rapidly progressive malfunction in the digestive tract, leading to vomiting and/or diarrhea. In adult vaccinated animals this translates into a chronic state of diarrhea and sometimes vomiting. This disease is known as inflammatory bowel disease (IBD), an autoimmune disease of the intestines. IBD has been occurring at near epidemic levels over the past several years; no other reasonable explanation has been proposed for the proliferation of cases of the disease.
