Vaccination with Dengue Tetravalent Vaccine (TDV) can help prevent dengue fever. The purpose of this study is to collect information of vaccination with TDV when given to children younger than 2 years. The main aims of this study are to learn how safe the vaccine is and how well it works to activate a young child's immune system (this is called immunogenicity). Children between the age of 6 and 21 months will receive two vaccinations with either TDV or placebo 3 months apart. Blood samples will be taken before and after the vaccination as well as throughout the study. These are necessary to check how well the vaccine works to activate the immune system. During the study, participants will visit their study clinic 8 times for vaccinations, blood draws and health checks."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '20 Months', 'minimumAge': '6 Months', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria\n\nParticipant eligibility is determined according to the following criteria:\n\n1.

Participant has previously received a vaccination against dengue virus (investigational or licensed).\n11. Participant has a clinically significant active infection (as assessed by the investigator) or body temperature greater than (\\>) 38.0 degrees Celsius (°C) (\\>100.4 degrees Fahrenheit \\[°F\\]) within 3 days of intended IMP administration on Day 1 (M0).\n12. Participant has used antipyretics and/or analgesic medications within 24 hours prior to vaccination. The reason for their use (prophylaxis vs treatment) must be documented. Trial entry must be delayed to allow for a full 24 hours to have passed since last use of antipyretics and/or analgesic medications.\n13. Participant has received any of the following:\n\n 1. A licensed vaccine within 14 days (for inactivated vaccines) or 28 days (for live vaccines) prior to IMP administration on Day 1 (M0). This includes co-administration with routine vaccines.\n 2. A coronavirus vaccine within 14 days prior to IMP administration on Day 1 (M0).\n 3. A vaccine authorized for emergency use within 28 days prior to IMP administration on Day 1 (M0).\n14. Participant is scheduled to receive any other vaccine within 28 days after IMP administration on Day 1 (M0).\n15. Participant is participating in any clinical trial with another investigational product 30 days prior to Day 1 (M0) or plans to participate in another clinical trial at any time during the conduct of this trial.\n16. Participant has taken part in any clinical trial of a dengue or other flavivirus (example, West Nile virus) candidate vaccine, except if it is known that the participant received placebo in the trial(s).\n17.
