Primary versus Secondary Immune Response
The primary immune response occurs the first time that the immune system comes in contact with the antigen. During this time the immune system has to learn to recognize antigen and how to make antibody against it and eventually gain immunological memory. This primary response takes time (about two weeks) and during this time the person experiences signs of illness. IgM antibodies are the hallmark of a new infection because they are the first antibodies made when a person is exposed to an antigen for the first time. After the body learns to make IgM antibodies, it will start making IgG antibodies to the antigen.
The secondary immune response occurs the second time (3rd, 4th, etc.) the person is exposed to the same antigen. At this point immunological memory has been established and the immune system can start making antibodies immediately. The antigen usually is killed within minutes and the person is not aware that he/she was attacked. The antibodies in this response are IgG and IgA or (in the case of allergy IgE).

Immune system facts?
The immune system is a complex network of cells, tissues, and organs that work together to protect the body from viruses, bacteria, and other harmful substances. It has two main components: the innate immune system, which provides immediate, general protection against pathogens, and the adaptive immune system, which develops a specific response to each pathogen. Immune cells like white blood cells, antibodies, and cytokines play crucial roles in identifying and destroying harmful invaders while also maintaining tolerance to the body's own cells. A healthy immune system is essential for overall well-being, and lifestyle factors like diet, exercise, sleep, and stress management can all influence its function.
Of the 2 branches of the immune system which system begins to respond immediately?
The innate immune system is the branch of the immune system that responds immediately to pathogens. It provides rapid but non-specific defense mechanisms, such as physical barriers and inflammatory responses, against a wide range of invaders.
