RBD-specific Ab levels stratified by symptoms and analgesic use.
Pairwise means of RBD ELISA OD450 by pain reliever group for the top three vaccine induced symptoms are shown. Horizontal dashed line denotes the cut-off for seronegative status. Pairwise differences were compared using a two-sample t test with p value adjustment using the Tukey honestly significant difference. Total numbers of individuals tested in each category are shown below each plot.
