  Weeks 3, 5, 7, 9, 13, 25, 53

• Change in GMT of anti-SARS-CoV-2 B cell epitope antibody

  Week 9

• Change in IgG subclasses (IgG1 and IgG2) of anti-SARS-CoV-2 spike (S) glycoprotein-specific antibody

  Weeks 3, 5, 7, 9, 13, 25, 53

• Change in the neutralizing activity against pseudovirus of SARS-CoV-2

  Weeks 3, 5, 7, 9, 13, 25, 53

You may not qualify if:

• Subjects with symptoms of suspected COVID-19 infection (respiratory symptoms, headache, malaise, olfactory disorders, taste disorders, etc.)
• Subjects with a history of COVID-19 (hearing from subjects)
• Subjects who have participated in unapproved vaccine clinical trials

• Subjects who have current bronchial asthma
• Subjects who had a fever of 39.0°C or higher within 2 days after the last vaccination, and those who suspected allergy such as a systemic rash
• Females who wish to become pregnant from the date of study registration to 12 weeks after the first inoculation of the investigational drug, and pregnant females who are breast-feeding. In addition, females who may become pregnant and their male sexual partners should use appropriate contraceptives (pill), condoms, vasectomy, tubal ligation, diaphragm, intrauterine devices, spermicides, intrauterine hormone-releasing system, etc. from the study entry date until 12 weeks after the first vaccination
• Subjects who have participated in clinical trials of other unapproved drugs and received the investigational drug within 4 weeks before the start of this clinical trial (starting from vaccination day)
• Subjects who have been received a live vaccine, inactivated vaccine, or toxoid within 4 weeks before the start of this clinical trial (starting from vaccination day)
• Subjects who have been administered with drugs that affect the immune system (excluding external preparations) such as immunomodulators (DMARDs, etc.), immunosuppressants, biologics, etc. within 4 weeks before vaccination
