1
Passive immunity
refers to the acquirement of antibodies from an external source (temporary resistance)
2
Active immunity
refers to production of antibodies by one's self
3
Natural immunity
refers to the production of antibodies by one's body without artificial intervention (acquiring pathogen and its antigens naturally)
4
Artificial immunity
refers to the introduction of pathogens and its antigens through vaccines or injections
5
Herd immunity
a high proportion of a population is immunised or has the specific antibodies against an infectious disease, thereby preventing the spread of infection from person to person (protects newborns, AIDS, chemotherapy, elderly)
When a low proportion is immunised, a chain of infection is easily established (rapid spread)
