Brief Summary
TAK-919 is a vaccine in development to protect people against Covid-19. 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. At 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. Participants will be asked to record their temperature and any medical problems in an electronic diary for up to 7 days after each injection. During 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. The 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.

Up to Day 29 (28 days after first vaccination on Day 1)
Percentage of Participants With Unsolicited AEs for 28 Days Following Second Vaccination
Unsolicited AEs were all AEs that were not pre-defined for which the participant is not specifically questioned in the participant diary.

Percentage of participants with unsolicited SAEs until Day 57 was reported in this outcome measure.
Day 1 up to Day 57
Percentage of Participants With Medically-Attended Adverse Events (MAAEs) Until Day 57
MAAEs were defined as AEs leading to an unscheduled visit to or by a healthcare professional including visits to an emergency department, but not fulfilling seriousness criteria. Only unsolicited MAAEs data was planned to be collected and assessed for the assessment of this OM and solicited MAAEs was out of the scope of the assessment. Unsolicited MAAEs were those AEs that were not pre-defined for which the participant is not specifically questioned in the participant diary. Percentage of participants with unsolicited MAAEs until Day 57 was reported in this outcome measure.
Day 1 up to Day 57

Only unsolicited AE leading to discontinuation of vaccination data was planned to be collected and assessed for the assessment of this OM and solicited AE leading to discontinuation of vaccination was out of the scope of the assessment. Unsolicited AEs were those AEs that were not pre-defined for which the participant is not specifically questioned in the participant diary. Percentage of participants with any unsolicited AE leading to discontinuation of vaccination was reported in this outcome measure.
Day 1 up to Day 57
Percentage of Participants With Any AE Leading to Participant's Withdrawal From the Trial Until Day 57
Only unsolicited AE leading to participant's withdrawal data was planned to be collected and assessed for the assessment of this OM and solicited AE leading to participant's withdrawal was out of the scope of the assessment.

Day 1 up to Day 57
Geometric Mean Titers (GMT) of Serum Binding Antibody (bAb) Against SARS-CoV-2 on Day 57
GMT was the immunogenicity outcome expressed as reciprocal antibody titer with average for each group. Titer values measured as below lower limit of quantification (LLOQ) were imputed to a value that is half of the LLOQ. Titer values measured as above upper limit of quantification (ULOQ) were imputed at the ULOQ value. LLOQ=1 and ULOQ= 2052. GMT of serum bAb against SARS-CoV-2 was measured by ligand-binding assay specific to the SARS-CoV-2 spike (S) protein.
At Day 57
Geometric Mean Fold Rise (GMFR) of Serum bAb Against SARS-CoV-2 on Day 57
The GMFR was calculated as the ratio of the post-vaccination titer level to the baseline titer level. Where baseline was defined as the last measurement taken before the first dose of study intervention. GMFR of serum bAb against SARS-CoV-2 was measured by ligand-binding assay specific to the SARS-CoV-2 S protein.
At Day 57
Seroconversion Rate (SCR) of Serum bAb Against SARS-CoV-2 on Day 57
SCR was defined as percentage of participants with a change from below limit of detection (LOD) or LLOQ to equal to or above LOD or LLOQ, OR, greater than or equal to (\>=) 4-fold rises from baseline. LLOQ= 1, ULOQ= 2052. Baseline was defined as the last measurement taken before the first dose of study intervention. SCR of serum bAb against SARS-CoV-2 was measured by ligand-binding assay specific to the SARS-CoV-2 S protein.
