Today @natmedicine.bsky.social published our study showing the older individuals born prior to 1968 have more antibodies that cross-react to #H5N1 relative to younger individuals. If H5N1 causes a pandemic, children will likely be the most susceptible. 1/2

Immune history shapes human antibody responses to H5N1 influenza viruses - Nature Medicine
H5N1 strain-specific antibodies are higher in older individuals and correlate more with birth year than with age, suggesting that younger individuals are potentially more likely to benefit from H5N1 v...

Seems population immunity should be useful for forecasting flu, right? Using cross-sectional, age-representative neutralizing titers measured in the summer of 2017 in Philly, we find that the clade to which we infer the greatest susceptibility dominated the next season. Even more, we found...

Antibodies are the product of evolution on two timescales: over millions of years in vertebrate populations, and within weeks of infection or vaccination in populations of B cells. We ask how those timescales interact in our paper out in Plos Pathogens 🧵 1/n t.co/vRdGYYQwsU
Germline-encoded specificities and the predictability of the B cell response
Author summary Antibodies arise as B cell receptors encoded by the stochastic recombination of immunoglobulin genes. While those genes evolve over millions of years, the receptors themselves evolve wi...
