For A Vaccine To Protect A Dog From Disease... Aug 30 2014
Certain Conditions Must Be Met:
1. Presence of maternal antibodies does not block high titer vaccine. 2. Must be sufficient time between vaccination and disease exposure. 3. The strain of virus or bacteria vaccinated for must not mutate. 4. Vaccine must not be damaged. 5. Vaccine must be properly administered. 6. Proper Vaccine schedule must be adhered to. 7. Some breeds (Doberman’s, Rottweilers for example) must be vaccinated more frequently. 8. Animals immune
system must be adequately functioning. 9. Animal must not have ongoing viral infections or fever. 10. Nutrition. Animals who are malnourished, may not respond adequately to a vaccination. Poor nutrition, such as Vitamin A, Vitamin E, and selenium deficiencies, and restricted protein or calories can result in suppression of the immune system and vaccine failures.
