Question:
What is herd immunity?
Answer:
The resistance to an infectious organism because a large group of people is
immune to the infectious organism through immunization/vaccine. Herd or
Community immunity is contingent on the likelihood individuals are prone to
the infection will encounter the infected person.
For example, most of the people in the community are immune to an
infectious disease, which means everyone does not need immunity to prevent
the spread of the infection.
, Question:
What is active immunity?
Answer:
When the immune system produces antibodies in response to an antigen by
the vaccine, or by the infection itself.
For example, if a person who has never had hepatitis B contracts hepatitis B
and recovers from it, that person becomes immune to hepatitis B because of
the immune system's antibody response to the hepatitis B virus.
Question:
What is passive immunity?
Answer:
The immunity that occurs naturally. This type of immunity is passed on when
an antibody is produced in another host.
For example, immunity is passed on from a mother to her infant or by
artificial administration of antibody-containing formulations.
