What is immunization? List two diseases against which vaccines are available.
Immunization is the process in which a person's immune system is enhanced by giving inactive form of the disease causing agent ( immunogen). This agent develops the human immune system to fight against that agent and if attacked again by the same agent the immune systems give a more stronger response and eliminate the disease.
Two diseases for which vaccines are available are Polio and Diphtheria.
@Others:-Good answers, keep contributing!!
- When the immune system first sees an infectious microbe,it responds against it and remembers it specificaly.
- So the next time that particular microbe or it 's close relatives enter the body,the immune system responds with even more great vigour.
- This eliminates the infectioneven more quickly than first time around.
