Antigenic Drift Definitions:

  1. A small change due to mutation in the antigenic character of an organism that allows it to avoid attack by the immune system.

    Prescott's Microbiology 9th Edition by Joanne Willey, Linda Sherwood, Christopher J. Woolverton



  2. Minor antigenic changes in the influenza A virus due to mutations in the spikes' genes.

    Foundations in Microbiology by Kathleen Park Talaro, Arthur Talaro



Antigenic Drift Notes:

Antigenic drift is a process that takes places in viruses to generate variation by accumulating mutations in genes coding for antibody-binding sites. This drift causes the formation of a new strain that is not effectively targeted and attenuated by the antibodies. This makes the spread of virus easier in the host's body.
