Pre-existing cross-subtype serological responses against H5Nx in health care workers | Journal of Virology

Influenza A viruses (IAVs) are endemic in the human population and responsible for hundreds of thousands of deaths every year, occasionally leading to influenza pandemics. Since 2023, there has been a rise in avian IAV infections in humans, with some deaths reported, mostly related to the H5N1 subtype clade 2.3.4.4b. Seasonal vaccines against IAVs are effective, but their efficacy against avian IAVs is not well known. Here, following influenza seasonal vaccination in a cohort of adults, we report highly heterogeneous serological responses, possibly due to pre-existing immunity and HA sequence similarity. These findings provide insight into the breadth of pre-existing and vaccine-induced immunity against H5 influenza viruses and may inform the development of vaccination strategies aimed at providing broader protection against emerging influenza viruses.

Today's winning Biology All email--in fact this is a contender for best this year

El Niño is an absolute monster we have now surpassed the Super El Niño of 2015-2016 with peak expected in November-December 2026. We can’t truly know how significant the 1877-1878 El Niño was in equatorial Pacific clearly very significant, but this is at least strongest event in ~150 years.

The preliminary sea-surface temperature in the Nino 3.4 region just set a record 3.1°C above the 1991-2020 mean, but it's been very volatile. Best to wait for the 2-week window to pass. Conjecture: hurricanes are upwelling cooler waters in the Pacific, contributing to rapid SST changes.

'This is now getting absurdly serious with the El Niño. The latest OSTIA SST data now has a peak anomaly of 8.1C above normal, with Peru reporting a peak SSTA of 9.5C. What's more concerning is that these anomalies are only going to increase over the next 10+ days.' David Schlotthauer [x]
