During this time, the immune system has to learn to recognize the antigen and how to make an antibody against it. This process can take several days to weeks. The secondary immune responseRead more
The primary immune response occurs when an antigen comes in contact with the immune system for the first time. During this time, the immune system has to learn to recognize the antigen and how to make an antibody against it. This process can take several days to weeks.
The secondary immune response occurs when the same antigen is encountered again at a later time. Due to the presence of memory cells, the lag phase of the secondary immune response is shorter than that of the primary immune response. The secondary immune response is also stronger and faster than the primary immune response.
