The main aims of the study are to learn if TAK-919 can protect people from Covid-19 and to check for side effects from TAK-919.\n\nAt the first visit, the study doctor will check if each person can take part. Those who can take part will be chosen for 1 of 2 treatments by chance. Participants will either receive an injection of TAK-919 or a placebo in their arm. In this study, a placebo will look like the TAK-919 vaccine but will not have any medicine in it. 3 times as many participants will receive TAK-919 than placebo. Participants will receive 2 injections of TAK-919 or placebo, 28 days apart.\n\nParticipants will be asked to record their temperature and any medical problems in an electronic diary for up to 7 days after each injection.\n\nDuring the study, participants will visit the clinic for regular check-ups, blood tests, and sometimes for nose swab samples. When all participants have visited their clinic 28 days after their 2nd injection, the study sponsor (Takeda) will check how many participants have made enough antibodies to protect them against Covid-19.\n\nThe participants will stay in the study for up to 12 months after they have had their 2nd injection. During this time, the study doctors will continue to check how many participants have made enough antibodies to protect them against Covid-19. Also, they will check if participants have any more side effects from TAK-919 or the placebo.', 'detailedDescription': 'The drug being tested in this study is called TAK-919. TAK-919 is being tested to prevent infectious disease caused by Severe Acute Respiratory Syndrome coronavirus-2 (SARS-CoV-2). This study will look at the safety and immunogenicity of 2 doses of TAK-919 by intramuscular (IM) injection in healthy Japanese male and female adults, given 28 days apart.\n\nThe study will enroll approximately 200 healthy volunteers. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):\n\n* TAK-919 0.5 mL\n* Placebo- this is an injection that looks like the study drug but has no active ingredient\n\nAll participants will be asked to take intramuscular injection in the upper arm twice throughout the study.\n\nThis multi-center trial will be conducted in Japan. The overall time to participate in this study is 12 months from the second vaccination. Participants will make multiple visits to the clinic and will be contacted by telephone or a final visit after the last vaccination for a follow-up assessment.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '20 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
