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, ...

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

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 ...

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

In 2009, the world saw the first influenza pandemic in more than forty years in the form of the H1N1 strain. Although response to this variant was fast and a vaccine quickly developed, the fight ...

Antigenic Drift vs Antigenic Shift Even with careful research, a certain amount of educated guesswork is involved for manufacturers who select strains to incorporate into the annual flu vaccine.
