Reasons Dog Vaccinations Fail

Reasons why dog ​​vaccines fail:

1. Maternal antibody interference. This is one of the most common reasons for vaccination failure. Maternal antibody is an antibody that protects puppies from infectious diseases in the early stages, but each dog's individual immune response is different, and the vaccines used are not the same, so the success of vaccination Rates are also different.

2. Because of the vaccine and the failure to use the vaccine according to the regulations, it is also a reason for the failure of the vaccine injection. We all know that there are many types of vaccines, which are mainly divided into domestic and imported varieties. Therefore, when vaccinating dogs, you must choose vaccines produced by regular manufacturers.

3. Improper use of vaccines. Vaccines should not be injected in the buttocks. The buttocks have a lot of adipose tissue and few immune active cells. The antibody titer produced after injection is low, and the antibody declines quickly.

4. Variation of the vaccine virus. Even if the vaccination produces a high titer of antibodies, a small number of dogs may still get sick. This is because the virus can mutate, and existing vaccines target normal viruses. If the surface antigen of the virus has mutated, and the vaccinated dog is unfortunately infected with this mutated virus, it is still possible to get sick.

5. Genetic factors. Part of the reason for the failure of dog vaccinations comes from genetics. Faced with a wide variety of dogs on the market, some dogs have inherited maternal congenital immunodeficiency, so it is easy to fail in the vaccination. Different dogs respond differently to the same vaccine.

6. The dog's own nutritional deficiency is also the reason for the failure of vaccination. Therefore, when vaccinating dogs, you must choose the right time, when the dog is healthy. When vitamins A, D, B, E and various trace elements and complete protein are deficient, the production speed or quantity of immune antibodies will be affected.

7. The dog is in poor health. For example, if the parasites are not cleared, high fever or even getting angry, etc., it may cause immune failure and allergic reaction. Depending on the constitution, the allergic dog may have symptoms such as skin rash, rapid breathing, inexplicable diarrhea, edema, sunken eyes, etc. It should be sent to the pet hospital in time.
