An antigen is any substance that stimulates the body to make specific immunity. An antibody is the immunoglobulin made when B cells, activated by an antigen, become plasma cells.

1 Dog Vaccination Schedule

Specific immunity is the anti-infection ability an animal gains by contacting environment or microbes (bacteria, viruses, parasites) or by artificial vaccineโ€”the microbe acting as antigen. This is active immunity. Passive immunity comes from receiving external immune molecules (antibodies) or immune cells.

First vaccine: at 42 days, use the 5-in-1 (or 4- or 6-in-1) vaccine plus rabies vaccine. Note: the 5-in-1 covers distemper, parvovirus, rabies, parainfluenza, infectious hepatitis; the 4-in-1 covers distemper, parvovirus, parainfluenza, infectious hepatitis; the 6-in-1 adds rabies, Leptospira canicola, and Leptospira icterohemorrhagiae.

Second vaccine: 3 weeks after the first, again the 5-in-1 (or 4-/6-in-1) plus rabies.

Third vaccine: 3 weeks after the second, the 5-in-1 once more.

Booster: any vaccinated dog needs a booster every six months.

Notes:

Rabies and encephalitis vaccines are optional, yearly. At 30 days, a healthy pup takes an oral dewormer (commonly fenbendazole), with a booster every 2โ€“3 months. Let alcohol disinfectant dry before injecting; don’t let it touch live vaccines. Inject subcutaneously; only healthy dogs get vaccinated, with immunity in 10โ€“15 days.

Use vaccines in date; mix inactivated vaccine before use, discard after thaw. Live vaccines must be frozen; dilute with saline just before use. After injection, observe 20โ€“30 minutes before leaving.
