How is immunological memory maintained?
Immunization is a process designed to help our bodies fight off a particular infection caused by a pathogen in a more effective way, it strengthens the bodies immune response.
Vaccination is the most widely used form of immunization:
considering an example.
Upon vaccination, our bodies produce antibodies specific to the particular pathogen which has been introduced into our bodies.
these antibodies fight off all the pathogens which are causing an infection.
Now all that remains, are these antibodies which have a memory factor and they can remember the pathogen they fought against for years, they remain in circulation in the body , so next time in future if we are infected by that same pathogen our body will be very quick in recognizing this pathogen and will fight against them. These antibodies maintain this memory for years in case of any future infection by the same pathogen
