In randomized, double-blind clinical trials of a new vaccine, subjects were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the first dose, 103 of 727 subjects in the experimental group (group 1) experienced vomiting as a side effect. After the first dose, 71 of 634 of the subjects in the control group (group 2) experienced vomiting as a side effect.
