However, at the 12M time point, while the SARS-CoV-2-specific CD8 + T cell frequencies were close to significance ( p =0.0534, Kruskal-Wallis test), only the CEF-specific CD8 + T cell frequencies were significantly higher than the non-specific Dextramer CD8 + T cell frequencies (p<0.0001, Kruskal-Wallis test).
