IFNγ T cell response to ancestral and Omicron BA.1 spike or pools of peptides covering regions mutated in BA.1 and their ancestral equivalents, measured by in-house IFNγ ELISpot at post-V2 timepoint (n = 59 participants selected from liver, rheumatic and inflammatory disease cohorts). Unpaired statistical comparisons were assessed with a Kruskal–Wallis test with post hoc Dunn’s testing (adjusted alpha = 0.003). * indicates statistically significant by Bonferroni-adjusted alpha. ***adjusted P < 0.001, ****adjusted P < 0.0001.
