True
The memory cells have a long life is born and remain in the body.when encountering the antigens for the second time they are mobilise quickly on become plasma cells, which secrete abundant antibodies and launch a stronger reactions to defend against the antigens in a shorter time.the human memory provides the efficient strategy to different against pathogens after a second intrusion.
Non pathogenic organism are those that do not cause disease.
A pathogenic organism is an organism which capable of causing disease

Activation also requires from helper T cells. 1 antigen antigen This activated cell then begins dividing into memory B cells, which will participate in the secondary immune response, and cells that will act as protein factories in this immune response. plasma During the primary immune response, these cells secrete cytokines During the secondary immune response, the rapidly, giving rise...

The primary immune response O occurs when memory cells are stimulated O has a lag period while B cells proliferate and differentiate into plasma cells O occurs more rapidly and is stronger than the secondary response O is another name for immunological memory

24) The aspect of the immune response that vaccines are based on is A) stimulation of phagocytosis. B) protection of the normal microbiota. C) inflammation and fever. D) stimulation of cellular, as opposed to humoral, immunity. E) production of memory cells and high antibody titers from pathogen exposure

A host organism needs time, often days, to mount an immune response against a new antigen, but memory cells permit a rapid response to pathogens previously encountered. A vaccine to protect against a particular viral infection often consists of weakened or killed virus or isolated proteins from a viral protein coat. When injected into a person, the vaccine generally does not cause an infection and illness, but it effectively teaches the immune system what the viral particles look like, stimulating...
