Passive immunity
|
1.
|
Active immunity is the permanent immunity produced by the antibodies of the host in response to a direct contact of an antigen.
|
Passive immunity is a short term immunity produced by the introduction of antibodies from outside of the host.
|
2.
|
Antibody production is induced by the infection or by immunogens.
|
Antibodies are not produced, but directly transferred.
|
3.
|
Active immunity involves both cell mediated and humoral immunity.
|
Passive immunity is due to the presence of ready-made antibodies.
|
4.
|
Natural active immunity is by clinical infection.
|
Natural passive immunity is by the transfer of antibodies through placenta.
|
5.
|
Artificial active immunity is vaccination
|
Artificial passive immunity is induced by infection of antibodies.
|
6.
|
A lag period is present
|
Lag period is absent.
|
7.
|
Active immunity is only effective after the lag period.
|
Passive immunity is immediately mediated (since lag period is absent).
|
8.
|
Active immunity is durable
|
Passive immunity is only transient.
|
9.
|
Active immunity offers effective protection against microbes.
|
Passive immunity is less efficient in offering complete protection.
|
10.
|
Immunological memory is present.
|
Immunological memory is absent.
|
11.
|
In active immunity, the subsequent doses with the antigen cause booster effect.
|
In passive immunity, the subsequent doses are less effective due to immune elimination.
|
12.
|
Negative phases may occur in active immunity.
|
Negative phase is absent.
|
13.
|
Active immunity is not applicable to immune deficient individuals.
|
Passive immunity is applicable to immune deficient individuals.
|
14.
|
No side effects.
|
It may cause reactions.
|
15.
|
An example of natural active immunity is fighting off a cold, allergic reaction may also consider.
|
Skin as a passive immunity, anti-venom is an example of passive immunity.
