3 reasons for dog vaccine failure:

1. 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.

2. Interference from maternal antibodies, which is one of the most common reasons for 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.

3. Nutritional factors. After the dog is vaccinated, the antigen entering the body will also produce different levels of immune responses, but this requires certain nutrients to pave the way. Therefore, if the dog's body lacks or lacks nutrients, especially vitamin A, , D, B, E and various trace elements and full-price proteins are deficient, the e-antibody cannot quickly generate the required amount, leading to stagnation of the immune response or a decrease in immune response ability. This will directly lead to Immunity failure.

Precautions for dog vaccination:

1. Before the dog is vaccinated, it is necessary to conduct a physical examination to see if the dog is healthy. It is convenient for dogs to receive vaccinations when they are in good health. Otherwise, not only will the dog’s immunity fail to increase, but it may also be life-threatening.

2. Dogs are not suitable for vaccination in many situations. For example, if the dog is sick, the dog is pregnant, the dog is unwell, etc., it is not suitable to be vaccinated.

3. Do not vaccinate newly purchased dogs. A newly bought dog is prone to stress reactions because it is in a completely new environment. If you take your dog to get vaccinated at this time, it can only be said to be beneficial and harmless, and the immunity will also be reduced. It is best to let the newly purchased dog adapt to the environment and relax it, and then take it for vaccination after about 7 days.
