Increases in levels of antibody subtype as observed in the placebo group (n = 24) following inoculation with the 23-valent pneumococcal vaccine which took place on Day 30. Data are means (μg/dl) ± standard deviations on Days 0, 51 and 72. P-values for the changes between baseline and days 51 and 72 are in the right hand columns.
