Figure 2. Cell-mediated immune responses after single dose vaccination with ChAdOx1 nCoV-19 and BNT162b2 vaccines. (A) Comparison of IFN-γ-producing T cell responses from baseline to 3 wks after first vaccination between ChAdOx1 nCoV-19 (AZ) and BNT162b2 (PF) vaccines. (B) Kinetics of IFN-γ-producing T cell responses induced by ChAdOx1 nCoV-19 vaccine (AZ) from baseline to 3 wks after vaccination. (C) Kinetics of IFN-γ-producing T cell responses induced by BNT162b2 vaccine (PF) from baseline to 3 wks after vaccination.
