Reasons for dog vaccination failure:

1. Genetic factors

There are many breeds of dogs, and their immunity is different. Even dogs of the same breed and different physiques have different immunity to the same vaccine. Some dogs may even have congenital immune deficiencies, leading to immune failure.

2. Interference from maternal antibodies

Puppies with too high maternal antibodies will interfere with the immune effect of the vaccine, while puppies with too low maternal antibodies may be in the latent infection period of infectious diseases when vaccinated, leading to immune failure.

3. Influence of nutritional factors

Lack or insufficiency of nutrients, especially vitamins A, D, B and various trace elements and full-price proteins, will affect the production speed or quantity of immune cells, leading to immune failure.

4. Vaccine reasons

The use of vaccines produced by informal biological products factories, poor vaccine quality, use of expired vaccines, inaccurate vaccination doses, etc. can affect the immune effect of the vaccine and even lead to immune failure.

Remedial methods after vaccine injection failure:

1. Strengthen nutritional supplements

Strengthen feeding and management, pay attention to protein nutrition supply, adapt to supplement vitamins and various trace elements, reduce various stress hormones, regularly deworm, enhance physical fitness, and improve dogs' resistance and immunity to diseases.

2. Scientific and rational use of drugs

Select drugs scientifically and rationally based on the nature and symptoms of the disease, as well as the severity of the disease, to avoid indiscriminate use and abuse of drugs. Use glucocorticoids, cytotoxic drugs and sex hormones with caution to avoid harm to immune organs and immune cells.

3. Adjustment of immune program

Refer to the immunization program recommended in the vaccine instructions, and formulate a scientific and reasonable immunization program based on factors such as the prevalence and patterns of epidemics in the region, the characteristics of the dog, the feeding and management conditions, and the type and nature of the vaccine.

4. Establish an epidemic prevention system

Help dogs receive regular vaccinations. A detailed check of the dog's health condition should be carried out before vaccination. It is emphasized that only healthy dogs should be vaccinated. Sick dogs should receive effective treatment and should not be vaccinated.

Things you need to pay attention to to avoid vaccination failure:

1. Vaccination contraindications

If the owner ignores some conditions in which the dog is not suitable for vaccination at that time and rashly immunizes it, or uses vaccines of poor quality, expired, improper storage, or even receives treatment from a hospital with low technology, it will definitely have negative consequences.

2. Dog rest and observe

When an unimmunized puppy arrives in a new environment, it must gradually adapt to its diet and rest. If the puppy comes from a market with a dirty environment, his physical condition must be very poor.

3. No injections after birth

You can get vaccinated if you are too youngCan be interfered by maternal antibodies, affecting immune effects. The first dose of basic puppy vaccine should be given after the puppy turns 45 days old, and the first dose of rabies vaccine should be given after the puppy turns three.

4. Observe physical condition

There are hundreds of diseases that can occur in dogs, and vaccines can only prevent six or seven of them. Even if the dog is vaccinated, you should pay careful attention to the health of the dog. If it is sick, it should be sent to the pet hospital for expert treatment in time.

5. Pay attention to annual vaccines

We must pay attention to the annual vaccine, and the annual vaccine should be injected about half a month earlier than the previous year to prevent accidents when the vaccine is about to expire.
