The purpose of the study was to assess the patterns of global gene expression in peripheral blood cells before and at three time points after the administration of a trivalent influenza vaccine in human male subjects, and to relate these to the antibody response to the vaccine. The antibody titer data for these subjects is provided as a supplemental file.

119 healthy male human volunteers ages 19 - 41 years were recruited in the study. Whole-blood RNA samples were collected in PaxGene tubes before and at three time points after administration of a trivalent influenza vaccine. Baseline samples (before vaccination) are labeled as day 0. The three additional time points are days 1, 3, and 14 after vaccination. A total of 431 arrays, corresponding to 116 individuals, passed quality control and are included in this data set. These are distributed as follows: Day 0: 111 Samples Day 1: 110 Samples Day 3: 101 Samples Day 14: 109 Samples
