    An solicited reaction (SR) was an adverse reaction (AR) observed and reported under the conditions (nature and onset) prelisted (i.e., solicited) in the electronic case report form (eCRF). Systemic AEs were all AEs that were not injection site reactions. They, therefore, include systemic manifestations as well as localized or topical manifestations that were not associated with the vaccination site. Solicited systemic reactions included Fever, Vomiting, Crying abnormal, Drowsiness, Appetite lost, and Irritability.

36. Number of Participants With Unsolicited Adverse Events

    Time frame: Within 30 days post any vaccination

    An AE was defined as any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An unsolicited AE was an observed AE that does not fulfill the conditions prelisted in the eCRF in terms of symptom and/or onset post-vaccination. These included both serious and non-serious events.

37. Number of Participants With Immediate Unsolicited AE

    Time frame: Within 30 minutes post any vaccination

    An AE was defined as any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An unsolicited AE was an observed AE that does not fulfill the conditions prelisted in the eCRF in terms of symptom and/or onset post-vaccination. These included both serious and non-serious events. Immediate Unsolicited AE were AEs reported within 30 minutes of vaccine administration.
