Brief Summary:
The primary purpose of this study is to assess humoral immune responses of 3 dose levels of Ad26.COV2.S administered intramuscularly (IM) as a 2-dose schedule (56 days apart); Ad26.COV2.S administered IM as a single vaccination; and to test both compressed and expanded 2-dose schedules of Ad26.COV2.S (28 and 84 days apart).

Condition or disease Intervention/treatment Phase
Healthy Biological: Ad26.COV2.S Other: Placebo Phase 2

Detailed Description:
The aim of the COVID-19 vaccine clinical development program is to develop a safe and effective vaccine for the prevention of COVID-19. Currently, there are no available vaccines for the prevention of coronavirus disease-2019 (COVID-19). Ad26.COV2.S (also known as Ad26COVS1) is a monovalent vaccine composed of a recombinant, replication incompetent adenovirus type 26 (Ad26) vector, constructed to encode the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus spike (S) protein, which will be assessed in this study. Also, different vaccination intervals and multiple lower dose levels compared to the dose levels in the first in human (FIH) study (VAC31518COV1001) will be assessed. The study consists of: screening phase (28 days), vaccination phase (1-3 months) depending on the vaccination interval, and follow-up ( 12 months). The study duration is approximately 15 months. The adverse events and other safety assessments including vital signs measurements (heart rate, supine systolic and diastolic blood pressure, respiratory rate, and body temperature) and physical examinations will be assessed during the study.
