Differences Between Antigenic Shift and Antigenic Drift

Differences Between Antigenic Shift and Antigenic Drift

Differences Between Antigenic Shift and Antigenic Drift Here are some differences: S.N. Characteristics Antigenic Shift Antigenic Drift 1. Definition Antigenic shift refers to the gene recombination occurring when influenza viruses re-assort. Mutations causing minute changes in the hemagglutinin and neuraminidase antigens on the surface of the Influenza virus is termed as antigenic drift. 2. Result in … Read more Differences Between Antigenic Shift and Antigenic Drift
