Multivariate analysis of humoral immune responses induced by the adjuvants. (A) The PLS-DA model was applied using all antibody features measured from mouse sera collected on days 14 and 28 after the first immunization. Groups included mice immunized with S protein alone, or S protein formulated with ILA or alum (n = 10 per group). (B) Loading factors of the first component were generated based on the PLS-DA model. The length and color of the bar represent the contribution level and the group with the highest loading values, respectively.
