| E.5 End points |
| E.5.1 | Primary end point(s) |
- Safety after the first vaccination: Occurrence, time to onset, number of days of occurrence, severity of solicited (prelisted in the subject diary and Case Report Form [CRF]) injection site reactions and systemic reactions occurring up to 7 days after the first vaccination. Occurrence, nature ([MedDRA preferred term), time to onset, duration, severity, action taken and relationship (for systemic events only) to vaccination of unsolicited (spontaneously reported) adverse events (AEs) up to 28 days after the first vaccination.
- Safety after the second vaccination: The endpoints will be the same as above. Additionally, occurrence and type of injection site reactions observed at the first vaccination site will be assessed (for a same subject the two study vaccinations will not be performed on the same side).
- SAE The occurrence, nature, time to onset, duration, severity and relationship to vaccination of serious adverse events (SAEs) during the whole study period will be reported.
