An allergic reaction i believe.
When an antibody attaches onto an antigen it destroys the antigen to help your body fight off a disease.
Allergy
true
Vaccination introduces foreign antigen and the body responds by producing antibodies for that specific antigen. So overall levels of antibody may not considerably increase, but antibodies specific for that antigen will increase dramatically.
Allergies develop when the body overreacts to an antigen.
A substance that contains the antigen of a pathogen is known as a vaccine. Vaccines are designed to stimulate the immune system by introducing a harmless form or component of the pathogen, such as proteins or inactivated viruses. This exposure helps the body recognize and mount an immune response against the pathogen if encountered in the future, providing immunity.
Anti is a prefix meaning against, the opposite of, or opposed to.
hypersensitivity
Many different types of lympocytes exist. Each type recognizes one specific antigen and responds by dividing to form a clone. This clone then secretes a specific antibody agaist the antigen.
An artificial or weakened antigen is commonly referred to as a "vaccine." Vaccines are designed to stimulate the immune system by introducing a harmless form or component of a pathogen, which can be either inactivated (killed) or attenuated (weakened). This helps the immune system recognize and mount a defense against the actual pathogen if encountered in the future, thereby providing immunity.
A diverse array of antibodies can be generated against a single antigen through a process called somatic hypermutation. This process allows B cells to produce a wide range of antibodies with different binding affinities to the antigen, increasing the chances of finding an effective antibody to neutralize the antigen.
Occasionally a person will be missing the RhD antigen that is normally found in type B negative blood. This is a rare but harmless event and is not symptomatic of any other propensity for illness.
