New bird flu vaccine could tackle multiple variants with one shot

<h2>00:46 A multi-variant avian flu vaccine that could enhance pandemic preparedness</h2><p>A vaccine capable of protecting against multiple strains of avian influenza virus might be a step closer, according to new research. The H5 subtype of avian influenza viruses has spilled over into mammals and is particularly concerning to researchers because of the risk that one of its variants may evolve to cause a pandemic. But because there are multiple variants of these viruses, it has been hard to pre-prepare vaccines. Now, a team has used information on how H5 viruses changed over time to design a vaccine that in animal studies provided protection against different H5 variants. They hope their approach could be applied to create stockpiles of a vaccine that could be used in the event of a pandemic, regardless of the variant that causes it.</p><br><p><em>Research Article: </em><a href="https://www.nature.com/articles/s41586-025-09626-3" rel="noopener noreferrer" target="_blank"><em>Kok et a...
