Immunological memory refers to the ability of the immune system to react previous antigen infections.
<h3>What are primary and secondary immune responses?</h3>
The primary immune response refers to the initial interaction between the immune system with pathogenic microorganisms (e.g., bacteria).
The secondary immune responses refer to the second contact with the same pathogenic organism, which enables to the organism create specific antibodies against this pathogen through a process called immunological memory.
Active Immunity is a term used to refer to a type of acquired immunity caused by previous exposure to a pathogenic microorganism and/or vaccine inoculation.
Immunological memory leads to a faster and better response of the immune system against pathogen reinfection.
In conclusion, immunological memory refers to the ability of the immune system to react previous antigen infections.
