In 1958, a new strain of influenza A with different HA and NA was identified and antigenic shift was discovered; the need for a trivalent vaccine was recognized. Technical advances have made it ...

These strains occur because of the phenomenon known as antigenic shift, in which humans are infected with avian influenza viruses or viruses that contain a combination of genes from human and ...

Catani and colleagues provide data on antigenic properties of neuraminidase proteins of pandemic H1N1 and show that antigenic diversity of the neuraminidase from 2009 to 2020 largely falls into two ...

Influenza is one of the most unpredictable ... Every now and then, the virus changes dramatically in a process called antigenic shift. When this occurs, people become even less immune, and the ...

To comprehend how this is possible, it is necessary to understand how influenza viruses are passed ... to form a new strain that is called antigenic shift. Such a significant mutation occurs ...

"This strategy is known as antigenic variation," explains physicist Maria Colomé-Tatché, who is Professor of Functional Genomics and Cell Biology at LMU's Biomedical Center and leader of the ...
