Brief Summary

TAK-019 is a vaccine in development to protect people against Covid-19. The main aims of the study are to learn if TAK-019 can protect people from Covid-19 and to check for side effects from TAK-019. 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-019 or a placebo in their arm. In this study, a placebo will look like the TAK-019 vaccine but will not have any medicine in it. 3 times as many participants will receive TAK-019 than placebo. Participants will receive 2 injections of TAK-019 or placebo, 21 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 attended a clinic visit 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-019 or the placebo.

  • Geometric Mean Titers (GMT) of Serum Immunoglobulin G (IgG) Antibody Levels to SARS-CoV-2 Recombinant Spike (rS) Protein on Day 36

    GMT was the immunogenicity outcome expressed as reciprocal antibody titer with average for each group. Titer values was measured as below lower limit of quantification (LLOQ) were imputed to a value that was half of the LLOQ. LLOQ was equal to 200. Here, ELISA is Enzyme-linked immunosorbent assay.

  • Seroconversion Rate (SCR) of Serum IgG Antibody Levels to SARS-CoV-2 rS Protein on Day 36

    SCR was defined as percentage of participants with 4-fold or more rises in titer if naive at baseline OR percentage of participants with 2-fold or more rises in titer if seropositive at baseline. Baseline was defined as the last measurement taken before the first dose of study intervention.

    At Day 36

  • Seroresponse Rate (SRR) of Serum IgG Antibody Levels to SARS-CoV-2 rS Protein on Day 36

    SRR was defined as percentage of participants with greater than or equal to (\>=) 95 percentile in titer at Baseline for all participants. Baseline was defined as the last measurement taken before the first dose of study intervention.
