Flu vaccination does more than protect against viruses circulating that year. Our study published in #ScienceTranslationalMedicine showed historic 1994 vaccine generated broad immune responses against future H1N1 & FluB strains, but not H3N2, spanning 30 years. www.science.org/doi/10.1126/...

Historic 1994 influenza vaccine cohorts define breadth of antibody and B cell responses toward future influenza A and B viruses
B cell responses that bound to future H1N1 and influenza B virus strains, but not H3N2 strains, were elicited in adults by the 1994 influenza vaccine.

New research shows getting your annual flu vaccine can protect you from seasonal influenza strains and prime your immune system to respond to future strains, even some that emerge decades later. Find out more 🔗 bit.ly/4saTNBw

Looking back to protect the future: New insights into influenza immunity
A new study from the Doherty Institute shows that seasonal influenza vaccination does more than protect against viruses circulating that year; it can also prime the immune system to respond to future strains, including some that emerge decades later.

Our paper exploring the effects of solid tumor malignancy-associated inflammation upon COVID-19 vaccine-induced antibodies is finally live! We show that while dysregulated inflammation impairs neutralization, variant cross-reactive Fc effector functions remain robust. www.nature.com/articles/s41...

Happy to have the latest @amywchung.bsky.social lab preprint online! 🦠 Here we demonstrated that systemic inflammation in solid tumor malignancy patients was associated with impaired SARS-CoV-2 neutralizing antibody functions while non-neutralizing functions remained robust (yay Fc functions!) 🦠

1/ Hot off the press in @jimmunol.bsky.social. We investigated how same side (ipsilateral) vs alternate side (contralateral) prime-boost vaccination impacts germinal center (GC) dynamics & antibody responses against SARS-CoV-2 spike in mice.💉🦠#immunology #vaccines @thedohertyinst.bsky.social

Fantastic to have our study out describing the nuances of increased SARS-CoV-2 IgG4 following repeated mRNA vaccination 💉💉💉 @amywchung.bsky.social @kev-in-science.bsky.social @viralvaxlab.bsky.social And great discussion started below!
