check on learning
Preformed Abs are injected (or T cells)
passive immunity
Immediate protection with no lag
passive immunity
Short-lived protection since Abs are quickly eliminated
passive immunity
No immunologic memory since preformed Abs are injected
passive immunity
Decreasing levels of immunity with repeated doses
passive immunity
Useful for protecting immunodeficient people
passive immunity
Developed by infection or immunization
active immunity
Lag period since protection must be generated
active immunity
Effective immunity is generally long-lasting
active immunity
Immunologic memory induced since host makes its own response
active immunity
Level of immunity generally increases with repeated exposure/immunization
active immunity
Not very effective in protecting immunodeficient people
active immunity
