Discuss what is meant by immunocompetence, immune specificity and memory, and ad

Adaptive immunity is the protection of a host organism from a pathogen or toxin. It is mediated by B cells and T cells, and is characterized by immunological memory. Adaptive immunity is highly specific to a given antigen and is highly adaptable.


Immune specificity is the ability to react against one type of pathogen without concurrent cross-reactivity against other pathogens.


Immune memory is the way the body's immune system remembers vaccines or diseases it has been exposed to in the past. It requires cells like memory T cells.


Immunocompetence is the ability of the body to produce a normal immune response following exposure to an antigen.
