Study Description

Brief Summary:

This is a Phase 1/2, randomized, placebo-controlled, and observer-blind study in healthy Japanese adults.

• At a single dose level
• In adults 20 to 85 years of age

Condition or disease	Intervention/treatment	Phase
SARS-CoV-2 Infection; COVID-19	Biological: BNT162b2; Other: Placebo	Phase 1; Phase 2

Study Design

• Actual Enrollment: 160 participants
• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Masking: Double (Participant, Investigator)

   As measured at the central laboratory
3. SARS-CoV-2 S1-binding IgG levels, expressed as GMCs [ Time Frame: Through 1 year after dose 2 ]
   As measured at the central laboratory
4. GMFR in SARS-CoV-2 S1-binding IgG levels from before vaccination to each subsequent time point [ Time Frame: Through 1 year after dose 2 from baseline ]
   As measured at the central laboratory
5. GMR of the geometric mean of SARS-CoV-2 serum neutralizing titers to the geometric mean of SARS CoV 2 S1-binding IgG levels [ Time Frame: Through 1 year after dose 2 ]
   As measured at the central laboratory

Criteria

Inclusion Criteria:

• Japanese male or female participants between the ages of 20 and 85 years, inclusive, at randomization.
• Participants who are willing and able to comply with all scheduled visits, vaccination plan, laboratory tests, lifestyle considerations, and other study procedures.
• Healthy participants who are determined by medical history, physical examination, and clinical judgment of the investigator to be eligible for inclusion in the study.
• Capable of giving personal signed informed consent.

Exclusion Criteria:

• Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
