Fig. 3. SARS-CoV-2 Omicron BA.5/ancestral specific T cell
response and antibody neutralization ratios. Individual data points
comprise the ratio of Omicron BA.5 to ancestral (A, C) T cell
responses or (B, D) serum neutralization activity. Recent
Omicron BA.5 infection and bivalent booster vaccination are presented as
positive (+) or negative (-). (A-B) At T1, HCWs were divided
into two groups based on recent (i.e., <3 months) Omicron BA.5
infection. (C-D) At T2, HCWs were divided into four groups
based on recent Omicron BA.5 infection and receiving a bivalent booster
vaccination. Absolute values that were used to calculate these ratios
are presented in Supplementary Fig. 1A-D . Data are represented
as median with IQR and were assessed by a (A-B) Mann-Whitney U
test or (C-D) Kruskal-Wallis test with Dunn’s post hoc
analysis.
