Number (percentage) of subjects experiencing local solicited adverse events for each study arm receiving vaccine, by intensity grade for each immunization.

Note: N represents the number of participants randomized into each study arm, receiving at least one immunization. Denominators are participants receiving at least one immunization for each study arm. Each participant is counted at the most once for each event type per vaccination and the greatest reported intensity level is recorded. For the control group, the only observed event reported was mild tenderness (grade 1); 3 occurred following first immunization; 4 after the second immunization and 5 following the third immunization.
