The reasons why cats do not produce antibodies after vaccination:

1. They are in a state of immunosuppression. Cats with congenital immune deficiencies, immunosuppressive diseases, infection with internal and external parasites, use of immunosuppressive drugs or some antibiotics, etc., will put the cat in an immunosuppressed state. At this time, the immune system cannot produce enough to resist infectious diseases. protective power.

2. The injection period is wrong. For example, factors such as moving, changing food, traveling long distances, being frightened, etc. cause stress in dogs and cats, which may lead to immune failure.

3. Improper storage of vaccines. It is recommended that immunization be carried out in a regular pet hospital. Vaccines produced through informal channels cannot guarantee the integrity of the cold chain during transportation.

4. In the incubation period of infection. Vaccines generally reach maximum protection after 10 days. If you have been infected with the virus before sufficient protection is generated, the vaccine is injected during the incubation period of infection. Even with vaccination, disease outbreaks can still occur.

Notes on cat vaccination:

1. The vaccination must be carried out when the cat is in good health. If the cat is sick, it needs to be postponed.

2. Two days before and after vaccination, attention should be paid to reducing abnormal stimulation to pets and avoiding irritation to animals.

3. It is recommended not to take a bath within a week after vaccination and not to have contact with cats of unknown origin.
