In addition to study visits at Day 0, Day 7 and Day 30 to evaluate primary objective of the study, additional study visits are planned at Day 60 and 90 for further investigation of the immunogenicity and safety/reactogenicity profile of the formulations. A follow-up period has been set up in which the subjects will be contacted at Day 180, 270 and 360. During these contacts, the investigator (or delegate) will ask the subject if she has experienced any serious adverse events and/or any AEs leading to study withdrawal since Day 90/last contact (as applicable), as well as if she has become pregnant during the post-vaccination period. The investigator (or delegate) will also ask the subject about concomitant vaccinations/products/medications that she has received since Day 90/last contact (as applicable) and whether the she had a respiratory tract infection that needed medical attention. Contact should be preferably performed via telephone, or alternatively, if phone contact is not possible, through email/other means where the information can be fully collected.
