Why is the secondary immune response so much faster and so much greater than the primary immune response to a pathogen?
Thanks in advance.
Thanks in advance.
The secondary immune response is significantly more efficient than the primary response due to the presence of memory B and T cells. After the initial infection, these memory cells are established and can recognize the pathogen immediately upon re-exposure. This rapid recognition allows for a quicker immune response, as memory B cells have already undergone isotype switching and somatic hypermutation, resulting in antibodies with higher affinity for the antigen. This mechanism ensures a robust and swift defense against previously encountered pathogens.
