T-cell responses against Omicron variants BA.4/5 and XBB.1.5 in solid organ transplant recipients were robust after three doses of vaccine but lower than against the ancestral strain

A CITF-funded study, published in preprint and not yet peer-reviewed, found that vaccination induced robust SARS-CoV-2-specific T-cells responses against Omicron variant BA.4/5, in solid organ transplant recipients (SOTRs).
