Yes, white blood cells, specifically B cells, produce antibodies in response to antigens present on injected microorganisms. When these antigens are recognized, B cells are activated and differentiate into plasma cells that secrete specific antibodies designed to neutralize or mark the microorganisms for destruction. This immune response is a crucial part of the body's defense against infections.
Antigens
Hypertension
You exhibit Active Immunity when cells encounter anitgens and produce antibodies against them.
Antibodies
effective against soluble antigens than the insoluble antigen
Type A blood will produce antibodies against B antigens.
Antigen is a substance that can induce the generation of antibodies, any substance that can induce immune response. Antibody is a protective protein produced by the body in response to an antigen.
AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
blood serum containing antibodies against specific antigens; provides immunity to a disease
Barriers, The Inflammation Process, and Antibodies.
The injected microorganisms in a vaccine may have the same antigens as the live pathogen, but they are weakened or killed to prevent disease. This allows the immune system to recognize and build immunity against these antigens without causing illness.
Pathogens are the disease causing agent while antigens are found in the antibodies that fight against the pathogens. So in short, no they aren't the same.
