The original antigenic sin: When the body first encounters an infection it produces effective antibodies against its dominant antigens and thus eliminates the infection. But when it encounters the same infection, at a later evolved stage, with a new dominant antigen, with the original antigen now being recessive, the immune system will still produce the former antibodies against this old "now ...
Original antigenic sin; Vaccine adverse event; Other ways in which antibodies can (unusually) make an infection worse instead of better Blocking antibody, which can be either good or bad, depending on circumstances; Hook effect, most relevant to in vitro tests but known to have some in vivo relevances
Original antigenic sin, descriptive diagram. en:Original antigenic sin refers to the propensity of the body's immune system to preferentially utilize immunological memory based on a previous infection when a second slightly different version of that foreign entity is encountered.
An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the molecular structure of an antigen. In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. [1]
A theoretical framework explaining the workings of the acquired immune system is provided by immune network theory, based on interactions between idiotypes (unique molecular features of one clonotype, i.e. the unique set of antigenic determinants of the variable portion of an antibody) and 'anti-idiotypes' (antigen receptors that react with the ...
Antigenic drift occurs in both influenza A and influenza B viruses. (Confusion can arise with two very similar terms, antigenic shift and genetic drift. Antigenic shift is a closely related process; it refers to the more dramatic changes in the virus's surface proteins when the genetic material from two or more viruses mix together.

Depiction of the sin of Adam and Eve (The Garden of Eden with the Fall of Man by Jan Brueghel the Elder and Pieter Paul Rubens). Original sin (Latin: peccatum originale) in Christian theology refers to the condition of sinfulness that all humans share, which is inherited from Adam and Eve due to the Fall, involving the loss of original righteousness and the distortion of the Image of God.
