How do you describe 'active immunity'?

Question

I'm completing an assignment on equine biology. Any tips would be great :)

Answer 1

Active immunity develops from exposure to the virus - that is, the body creates various phagocytes, lymphocytes and antibodies to destroy the infection, then leave memory cells which launch a stronger immune response if the same virus enters the body again.

This is opposed to passive immunity which is developed through things like vaccinations, or for a natural example, breast feeding.

Answer 2

We need more info...be a bit more passific

Answer 3

Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response. Artificially acquired active immunity can be induced by a vaccine, a substance that contains the antigen. A vaccine stimulates a primary response against the antigen without causing symptoms of the disease

Active immunity is form the antigens that our body produces

whereas passive antibodies are form another source e.g,

vaccinations. Becasue the passive immunity is from another

source the body recognises it as alien to the body and

destroies it. However active immunity also produces memory

cells alongside the antibodies and means the body can fight

the disease if infected again.
