No. Many organisms are harmless, and the body will produce antibodies since the organisms are seen as foreign.
Many pathogens (harmful organisms) may not cause significant disease in many people. An example would be the poliovirus - in some people it causes paralysis; in others it causes minor illness, in others it causes no symptoms. In all cases, the person develops antibodies.
Vaccination exposes the person to the antigens without the pathogen being present, and so antibodies are formed before the exposure, and this process does not result in illness.

Absolutely but not definitely. People are probably exposed to much more bacteria in their day to day lives from rodents and insects than they realize and probably have had some immune response to the antigens to which they have been exposed.
A person who is B positive will have?
B antigens, antibodies to A, and Rh antigens
What is the antigenic determinant site is that portion of the antigens exposed surface?
that's the part where the antibody attacks.
B lymphocytes exposed to antigens can transform into plasma cells and produce large quantities of antibodies?
True
How has quarantine decreased the spread of communicable disease?
Quarantine is the practice of isolating a sick person from people who are not sick. Quarantine decreases the spread of communicable diseases by limiting the amount of people who are exposed to airborne germs.
What antigens are expressed if a person is blood type AB negative?
My daughter is AB negative , I am B positive and her dad it A negative
What protects the body from free antigens?
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
How are antibiotics produced in human beings and explain their uses?
Human body produces antigens when it is exposed to a small amount of virulent substance.
