Genetic factors

The dog's body's immune response to vaccination is controlled to a certain extent by genetic factors. And there are many types of dogs, and their vaccine responses are also different. This means that the same vaccine will have different reactions in different dogs. Some dogs may be vaccinated successfully, while some dogs will fail.

Maternal Antibody Interference

This is one of the most common causes of vaccination failure. Maternal antibodies are antibodies that protect puppies from infectious diseases in their early stages. However, the individual immune response of each dog is different, and the vaccines used are different, so the success of vaccination is very important. Rates are also different.

Nutritional factors

When the dog is vaccinated, the antigens entering the body will also produce different levels of immune responses, but this requires certain nutrients to pave the way. Therefore, if the nutrients in the dog's body are lacking or insufficient, especially when vitamins A, D, B, E and various trace elements and full-price proteins are lacking, the e-antibody will not be able to quickly generate the required amount, resulting in Immune response stagnation or immune response ability decreases, which will directly lead to immune failure.
