The deduced amino acid sequence at the cleavage site of the hemagglutinin was determined for 63 H5 and 50 H7 subtype avian influenza viruses isolated in North America and Pakistan since 1992. The ...

In a recent article published in Immunity, researchers proposed that vaccines targeting the immunosubdominant yet conserved hemagglutinin (HA) stem could trigger broadly neutralizing antibodies (bnAbs ...

Discover comprehensive details about Influenza Vaccine, Recombinant Hemagglutinin, including its pronunciation, uses, dosage instructions, indications, and guidelines on how and when to take it or ...

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses. The devastating respiratory virus, influenza A virus, utilize its hemagglutinin ...

The complete coding region of hemagglutinin genes from 26 influenza A viruses of H9N2 subtype isolated from chicken flocks in China during 1996-2001 was amplified and sequenced. Sequence analysis and ...

One of the challenges faced when developing influenza virus vaccines is the problem of how to protect populations in the face of spreading pandemics. With the advent of air travel, this readily ...

In a recent study published in Emerging Infectious Diseases, researchers performed a quantitative assessment of the age-stratified seroprevalence of hemagglutination inhibition (HAI) antibodies ...

We know how the flu is spread. We know the importance of getting a flu shot. But what we may not know is the difference between the strains, and how they are named. While a bit "inside biology" for ...

Do you remember the egg shortage of 2024? It wasn’t just a supply chain issue; it was a consequence of the H5N1 avian influenza -or bird flu- sweeping through poultry populations worldwide. While ...

Cold hemagglutinin disease is a chronic hemolytic anemia that is refractory to the usual treatments for hemolytic anemia mediated by a warm-reactive antibody; it may be associated with a low-grade ...
