The vaccine itself has a great impact on the success rate of vaccination

Vaccinating dogs is a quite necessary matter. Dogs that have never been vaccinated have a much higher chance of contracting infectious diseases than dogs vaccinated regularly. Aside from feeding methods, a major reason many dogs contract infectious diseases is lack of vaccination. Therefore, for the health of dogs, owners must pay attention to vaccination work. Of course, vaccines are not just given casually; there are certain considerations when vaccinating dogs.

1. Common Infectious Diseases Prevented by Vaccines

Generally, we vaccinate dogs with imported quadrivalent vaccines, which prevent diseases like canine distemper, parvovirus, infectious canine hepatitis, and canine parainfluenza. Of course, an annual rabies vaccine is also given to prevent the rabies disease we most worry about and fear.

2. How to Enhance Immune Effects

Many dogs are infected with infectious diseases despite vaccination, possibly caused by unsatisfactory immune effects. For dogs already immunized, booster vaccinations should be administered as prescribed by veterinarians. Since the initial vaccines differ, the timing of booster immunizations also varies. To further confirm the timing, antibody levels for canine distemper and parvovirus can currently be tested to determine when to reinforce immunity.

3. The Condition of the Dog When Vaccinated Is Important

We know vaccines must be administered while the dog is healthy; only a healthy physical state can actively generate higher active immunity. Thus, a health check is a must before immunization. If a dog shows any discomfort, vaccination is not recommended as it may increase the risk of infection.

Dogs to be vaccinated must be in good condition, showing no signs of drowsiness or lethargy. Body temperature should be maintained at a normal range of about 39°C. Healthy dogs generally have moist noses, no nasal discharge, no purulent eye discharge, and no oral disease. Their coat looks shiny, skin is free from ulcers or large rashes. Breathing is steady, with no coughing or wheezing. No vomiting or diarrhea. No severe parasite infections. The anal area is clean. These are the most basic requirements.

4. How to Check Immune Effects

1. Immune Adjuvant

To improve immune effects, especially during the initial vaccination, an immune adjuvant can be used simultaneously. Although most vaccines contain immune enhancers, it is recommended to inject an additional immune enhancer during clinical use. Common immune adjuvants for dogs include poly I:C and thymosin, among others.

2. Checking Immune Effects

After the immunization procedure is completed, immune effects should be checked to see if sufficient antibody levels have been produced. This can be done using antibody diagnostic kits.

We should understand that vaccinating dogs does not guarantee prevention of infectious diseases, only significantly lowers the chance. Vaccine failure can lead to dogs falling ill.

Reasons Causing Vaccine Failure Include:

1. Fake or Substandard Vaccines: Currently, there are many types of canine vaccines on the market, both foreign and domestic; single or multivalent; inactivated or attenuated. Due to differences in production technology, strains used, cells, vaccine protectants, and lyophilization conditions, vaccine quality varies greatly. The quality of the vaccine itself greatly affects the success rate.

2. Incorrect Immunization Method

3. Stress Reaction After Vaccination

4. Dog Already Ill Before Vaccination
