RNA-seq of human peripheral blood mononuclear cells following oral cholera vaccination


ABSTRACT: In this study we performed RNA-seq to identify human transcriptomic signatures associated with antibody responses to an oral cholera vaccine. We isolated total RNA from peripheral blood mononuclear cells of vaccinated volunteers who following two priming oral immunisations, had either strong or no antibody responses to the antigen components of the cholera vaccine. We performed a longitudinal and comparative PBMC transcriptional assessment of high vs low antibody vaccine responders at day 0, 19 and 44 post vaccination. We also identified unique and overlapping genes of low and high vaccine responders 0, 19 and 44 post vaccination.

Booster vaccination with a fractional dose of an oral cholera vaccine induces comparable vaccine-specific antibody avidity as a full dose: A randomised clinical trial.

Antibody avidity is an important measure of the quality of vaccine-induced immune responses. Murine and human studies suggest that antibody avidity may be augmented by limiting access to antigen. The primary objective of this study was to evaluate in primed Swedish adults if booster vaccination with fractional doses (1/5th and 1/25th) of a model oral vaccine, the cholera vaccine Dukoral®, results in higher avidity antibody responses compared to boosting with a full vaccine dose. We also evaluate  ...[more]
