ObjectiveLittle is known about the interplay between gut microbiome and SARS-CoV-2 vaccine immunogenicity. In this prospective observational study, we investigated associations between the gut microbiome, habitual dietary fibre intake, and mRNA vaccine-elicited immune responses, including anti-Spike IgG, avidity, and ACE-2 competition (surrogate neutralization). Design16S rRNA sequencing and short-chain fatty acid analyses were undertaken using stool samples collected from 48 healthy individual...
