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, ...

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 ...

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.

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

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

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 ...
