VYD2311 is a monoclonal antibody that attaches to the virus that causes COVID-19 and helps block it from entering your cells. It is being tested in adults and adolescents at least 12 years old. Participants in this study will be given a "study drug" that will be either VYD2311 or placebo.\n\nThe study drug will be given as a shot into the muscle in the participant\'s upper thigh or upper arm once a month with a total of 3 shots during the study.\n\nThis study will help researchers see how well VYD2311 works to prevent COVID-19 during the 90 days after the first shot. The study will also look at the safety and tolerability of VYD2311, how the study drug is processed by the body (pharmacokinetics), how the immune system reacts to the study drug (immunogenicity), and how well VYD2311 can block the virus from infecting cells (neutralization). To do these tests, your blood will be drawn at certain times during the study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '100 Years', 'minimumAge': '12 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\nParticipants are eligible to be included in the study only if all the following criteria apply:\n\n1.

Note: Adolescent enrollment is allowed only if permitted by the local health authorities and local ethics committees.\n2. Has uninterrupted access to a device (eg, mobile phone, tablet) enabled to receive study reminders (eg, SMS text messages). The parent/guardian of adolescent participants will receive the study reminders.\n3. Provides written documentation of informed consent by signing a current IEC/IRB-approved ICF at the time of Screening. In the case of adolescents, parental informed consent and adolescent assent must also be obtained.\n4.

For participants assigned female sex at birth:\n\n 1. Is not of childbearing potential, OR\n 2. Is of childbearing potential and practicing adequate contraception for at least 7 days before dosing on Day 1, agrees to practice adequate contraception through 6 months after any dosing, and has a negative pregnancy test result on Day 1.\n\nNote: Pregnant participants will be eligible for enrollment after iDMC review of safety data only upon Sponsor communication to sites and only in regions permitted by local health authorities and local ethics committees. If pregnant participants are eligible for enrollment, this criterion is no longer applicable.\n\nExclusion Criteria:\n\nParticipants are excluded from the study if any of the following criteria apply:\n\n1. Prior receipt of VYD2311 or pemivibart (VYD222) within 12 months before Day 1 or plans to receive pemivibart within 90 days after Day 1.\n2. Prior receipt of convalescent plasma or a mAb to SARS-CoV-2 active against currently circulating variants within 120 days before Day 1 or plans to receive convalescent plasma or an active SARS-CoV-2 mAb within 90 days after Day 1.\n3. Tests positive for current SARS-CoV-2 infection by local RAT or RT-PCR on Day 1.\n4. Prior known or suspected SARS-CoV-2 infection within 120 days before Day 1.\n5. Exposure to someone with known or suspected SARS-CoV-2 infection in the 5 days before Day 1.\n6. Is acutely ill, including symptoms suggestive of SARS-CoV-2 infection, in the opinion of the investigator or has a fever ≥38 o C (≥100.4 o F) within 3 days of Day 1.\n7. Received or plans to receive a non-COVID-19 vaccine within 7 days before or after each dose of study drug.\n\nNOTE: Other protocol defined inclusion/exclusion criteria apply'}, 'identificationModule':
