When antigenic shift occurs, it is possible that an H1N1 virus and H3N2 virus may interact to produce an H1N2 virus and an H3 N1 virus, for example. Figure 3: Representation of genome segment ...

Pandemics resulting from antigenic shift. An example of a pandemic resulting from antigenic shift was the 1918-19 outbreak of Spanish Influenza. This strain was originally the H1N1 avian flu, ...

Antigenic Shift vs. Antigenic Drift. Sound the same, very different. In simple terms, the Antigenic DRIFT is when viruses mix and match their genes with that of a different virus. Hence, a big, sudden ...

The other form of change is "antigenic shift," which is a sudden and massive shift in the influenza virus' surface proteins, ... Examples are the swine flu (H1N1) pandemic of 2009 and the far more ...

The paper, published January 12 in BioEssays, reveals how the pandemic challenges the traditional understanding of 'antigenic shift' , given that the virus emerged from an existing influenza subtype.

Until now, little was known about the mechanisms behind these changes in antigen expression. This gap in our knowledge has ...

Tamping down on Omicron may increase the risk of an ‘antigenic shift’ to a far deadlier supervariant.

Antibodies in person A, for example, may mount an attack in which antibodies focus on a single antigenic region. Mutant viruses that arise in person A can escape antibodies by replacing one ...
