Anti-N immunity in individuals who received inactivated SARS-CoV-2 vaccines. Anti-N antibodies were quantified in the sera of individuals vaccinated with Sinovac (n = 55) and Sinopharm (n = 83). Correlation between anti-N and anti-S antibodies in subjects vaccinated with Sinovac (A) or Sinopharm (B) are shown. (C) Positive CD4/CD8 immune response consisting of positivity of CD4 and/or CD4 and CD8 T cell responses is shown according to the range of anti-N antibody index. (D) The ROC curve predicting the positivity of CD4/CD8 immune response according to the positivity or negativity of anti-N antibody is shown. The area under curves (AUC) and the p value of the ROC curve are indicated.
