Fig 2. Magnitudes of IFN-γ and IL2 responses of asymptomatic, symptomatic participants before and after infection, and healthy uninfected participants, to S, N+M, and CD4+CD8 pools.

Pre-infection (Pre) and maximum IFN-γ and IL2 responses post-infection (Post) to S, N+M, and CD4+CD8 peptide pools of asymptomatic and symptomatic participants, and healthy uninfected participants (Pre = baseline and Post = post-baseline). Significance of differences between Pre and Post *** p = <0.001.
