Passive immunization

[Tina]

Passive immunization involves giving

Antibodies to an organism
A toxin produced by an organism

Passive immunization is provided in the following circumstances:

When people cannot synthesize antibody
When people have been exposed to a disease that they are not immune to or that is likely to cause complications
When people have a disease and the effects of the toxin must be ameliorated

Passive immunization does not induce natural immunity.
