We find that subclade K viruses are antigenically advanced; however, this year's flu vaccine surprisingly elicited antibodies in many individuals that efficiently recognized these viruses. The implications are clear: go get this year’s vaccine if you haven’t already!

Antibodies elicited by the 2025-2026 influenza vaccine in humans
A new H3N2 variant (named subclade K) possesses several key hemagglutinin substitutions and is circulating widely during the 2025-2026 influenza season. In this report, we completed experiments to det...

Avian influenza isn’t new. But the most recent outbreak’s rapid and prolific spread is setting off alarm bells. While the H5N1 virus may have started in birds, it spread through multiple species. That's part of what makes it so difficult to defeat.

“Tracking H5N1 in wildlife risks becoming overwhelming now that the virus is so geographically widespread and affects so many species.” www.nature.com/articles/d41...
Could tracking animals’ health help to avert the next pandemic?
Avian influenza is sweeping the globe and infecting dozens of species. Advocates of an approach called One Health are calling for broad surveillance of wildlife, livestock and pets.

This year, researchers advanced H5N1 research showing that the virus in dairy cattle retains avian features, posing low pandemic risk, and that pasteurized milk with inactive viral components is safe. Studies also identified key S. aureus virulence mechanisms in natural host models.
