Correlation of titers for postvaccination sera. Each data point represents results from one individual, with identical values represented by a single point. The statistical significance of the correlation was determined by the t value of the Pearson product-moment correlation coefficient with df = n − 2. (A) CHO assay titers plotted versus ELISA titers for postvaccination sera. (B) PBMC titers plotted versus ELISA titers for postvaccination sera. (C) PBMC assay titers plotted versus CHO cell assay titers for postvaccination sera. T, titer.
