Avian influenza antigens found in dead wild mammal for 1st time Avian influenza antigens of the H5 strain have been detected ...

The H5N1 avian influenza virus is mutating to evade immune defenses in mammals following prior infection or vaccination.

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 ...

Pandemic influenza remains a significant global health threat, as signalled by the circulation and cross-species transmission of avian influenza A(H5N1) viruses from the clade 2.3.4.4b, including ...

Influenza virus is injected into fertilized eggs ... the virus that triggers a response from the immune system, called an antigen, is harvested and used in the flu shot, according to researchers.

Meanwhile, current influenza vaccines ... new modular technology that can accommodate glycoprotein antigens from many different viruses in a thermostable vaccine, making it possible to have ...

The two major antigens on the surface of influenza viruses are hemagglutinin and NA, and influenza viruses are known for their ability to mutate, Lucar said. One such mutation could be for the NA ...

There are 16 different hemagglutinins and nine different neuraminidases, and reassortment of these two antigens determines the influenza A virus subtype (e.g., H1N1 or H3N2). Embedded within the ...
