Fig. 3: The ratio of the response against the Omicron spike protein to the response against the WT spike protein.
From: BNT162b2-induced memory T cells respond to the Omicron variant with preserved polyfunctionality
a,b, The ratio of the frequency of cytokine-producing T cells against the Omicron spike protein to the frequency of cytokine-producing T cells against the WT spike protein was determined for each cytokine in each individual. CD4+ (a) and CD8+ (b) T cells were analysed in HCWs with two or three doses of the BNT162b2 vaccine and in COVID-19-recovered individuals with two BNT162b2 vaccine doses. Positive responders for each cytokine against the WT spike protein were included in this analysis. Data are presented as mean values ± s.d.
