Vulnerable Population
Vulnerable populations are selected (isVulnerablePopulationSelected = true). The trial includes pregnant participants and infants born to participants. Consent-related documents present in the submission include: L1_DK_SIS-ICF_Pregnant Participants (Danish), L1_DK_SIS-ICF_Parent of Infant (Danish, redacted) and L1_DK_SIS-ICF_Power of Attorney Between Parents (Danish). Inclusion criteria require participants to be capable of giving personal signed informed consent; infant participation is addressed via Parent of Infant ICF and a Power of Attorney Between Parents document (documents are in Danish as per filenames).

Inclusion criteria

  • {"criterion_text":"- 1. Participant living in Denmark or South Africa who has participated either in Trial MVX0004 or MVX0005 and has received at least 1 dose of the GBS-NN/NN2 vaccine\n- 2. Participant who is able to read and understand and capable of giving personal signed informed consent\n- 3. Participant who is willing and able to comply with scheduled visits, the investigational plan, and other trial procedures\n- 4. Participant who is granting access to their trial-related medical records and to their trial materials from Trials MVX0004 or MVX0005, whatever is applicable\n- 5.
