Brief summary

The mean and median score of the Faces Pain Scale-Revised (FPS-R) after each vaccination. The FPS-R is a validated scoring system for the assessment of acute pain in children from 4 years onwards

Detailed description

The mean and median score of a Numeric Rating Scale (NRS), as judged by the parent/legal guardian after each vaccination., The mean and median score of a NRS for each aspect of the usability parameters ‘ease of use’ and ‘safety’., Percentage of participants that have rabies antibodies ≥ 0.5 IU/ml on day 28 after the third dose of study vaccine. A titre ≥ 0.5 IU/ml is defined as an adequate seroconversion after vaccination according to WHO standard., Count and percentage of solicited and unsolicited AEs up to day 7 after each vaccination. Categories: mild, moderate, severe., Count and percentage of related and unrelated MAAEs resulting in study discontinuation and SAEs throughout the study period., The mean and median score of the Children’s Fear Score (CFS) after each vaccination., The mean and median score of a Numeric Rating Scale (NRS), as judged by the parent/legal guardian after each vaccination.
