Such annual epidemics are caused by newly circulating influenza A and B virus strains generated by the process of 'antigenic drift' ( Box 2 ), and seriously affect an estimated 3–5 million ...

Dr Golly says an antigenic shift can cause big, pandemic-scale problems – but this doesn’t happen often. “We see the antigenic drift every year, but the antigenic shift we don’t ...

With this virus, you get both antigenic drift and shift. Drift is when the virus replicates, accumulating small genetic variations—less tightly controlled than in the human body. Shift, on the other ...

Abstract and Introduction Abstract The isolation of influenza virus 80 years ago in 1933 very quickly led to the development of the first generation of live-attenuated vaccines. The first ...

Antigenic drift rendered this vaccine ineffective in the 1946 flu season. Unlike the polio or smallpox vaccine, which could be administered once for lifelong protection, the influenza vaccine needed ...

Every now and then, the virus changes dramatically in a process called antigenic shift. When this occurs, people become even less immune, and the likelihood of disease spread dramatically increases.

Antigenic shift and Antigenic drift in viruses Antigenic shift is a process where two or more different strains of a virus combine to create a new subtype of virus. Often, this new viral strain will ...
