Definition of vaccine

A vaccine is actually a virus that has been weakened, reduced in activity, or inactivated. After being injected into dogs, the weakened and inactivated virus cannot affect healthy dogs due to their resistance, but it can stimulate the production of antibodies against the virus in dogs, making them more vulnerable to stronger viruses in the future. The increased antibodies are enough to cope.
It should be noted that the vaccine only prevents viruses that spread in the air, but cannot prevent contact transmission and blood transmission. For example, the amount of virus in the air is defined as "unit 1", while the amount of virus in the urine of a dog with canine distemper is about "10,000 units", which is not an order of magnitude at all. Therefore, even if the dog After getting vaccinated, don’t take it lightly!

Canine core vaccines, which must be vaccinated:

Canine distemper virus: CDV, attenuated live vaccine
Canine parvovirus type 2: CPV- 2. Live attenuated vaccine
Canine adenovirus type 2: CAV-2, live attenuated vaccine
Rabies virus: inactivated vaccine

Non-core vaccines for dogs, vaccinate according to veterinarian recommendations:

Parainfluenza Viruses: CPiV, live attenuated vaccine
Leptospira: inactivated vaccine
Borrelia burgdorferi: Lyme disease, inactivated vaccine
Bordetella bronchiseptica: live attenuated vaccine
/>Canine influenza virus: CIV, H3N8 inactivated vaccine

Vaccines are not recommended for dogs, and vaccination is not required:

Canine coronavirus: CCV, inactivated live attenuated vaccine
CCV infection is common are subclinical, or cause only mild clinical symptoms. There is currently no evidence that existing vaccines protect against different pathogenic variants of CCV.
