In order to evaluate human immune responses in depth, I helped initiate and coordinate one of the initial studies from the NIH Center for Human Immunology, which focused on immune responses to vaccination for influenza. This study was designed to help build a data base of normal human variation (the human immunome) and to understand how variation in immune states contributes to immune responses and disease (Tsang, Schwartzberg et al, Cell 2014).
As a follow-up to these studies, Dr. John Tsang's laboratory performed CITESeq technology to uncover specific cellular contributions to baseline states (or set points) that contribute to responsiveness to vaccines (Kotliarov et al Nat Med 2020). Strkingly, these same signatures can predict severity of certain types of Lupus. To further understand responses to immunization, the CHI conducted a follow-up study comparing responses to both an unadjuvanted and an adjuvanted vaccine against Influenza H5N1. To complement this work, we have added new assays, including Somologics for indepth analyses of serum analytes and CITE-Seq.
In the last year, we have had two papers accepted that have examined responses to adjuvanted vaccines using high dimensional assays including CITE-Seq. Notably, responses to adjuvants parallel findings on baseline status that contribute to vaccine efficacy, providing common themes on immune responsiveness to vaccination that may help inform evaluation of new vaccines including those for SARS-CoV2 (Apps et al, accepted; Mule et al,Immunity PMC 38697118).
