Wow, I remember that term used in a microbiology lecture fifty years ago! To my recollection, when an infant makes an antibody to to a certain foreign protein - an influenza virus, for example - the infant will subsequently preferentially make antibody against that protein when confronted with a similar but different antigen. It has been used to explain why we don't acquire permanent immunity to colds, flu, and perhaps many other infections.Source(s): Disclosure compels me to state that my grades in theology were better than those in immunology.
