Brief Summary:
The purpose of this study is to assess the safety and immunogenicity of MVC-COV1901 vaccine compared to placebo in participants who are generally healthy or with stable pre-existing health conditions.

Condition or disease Intervention/treatment Phase
Covid19 Vaccine Biological: MVC-COV1901(S protein with adjuvant) Biological: MVC-COV1901(Saline) Phase 2

Detailed Description:
This is a Phase II, prospective, placebo-controlled, double-blinded (investigator/site staff and participants), multi-center, multi-regional study; the Sponsor will be blinded until the interim analysis. Participants who are generally healthy or with stable pre-existing health conditions will be randomized, stratified by age (≥ 20 to < 65 years and ≥ 65 years of age).All eligible participants will be randomized to receive 2 doses of either MVC-COV1901 or placebo in a predefined ratio.

    To evaluate the safety and tolerability of MVC-COV1901 from Visit 2 (Day 1) to Visit 7 (28 days after the second dose of study intervention) in terms of the number and percentage of participants with the occurrence of:

    • Solicited local AEs (up to 7 days after each dose of study intervention)
    • Solicited systemic AEs (up to 7 days after each dose of study intervention)
    • Unsolicited AEs (up to 28 days after each dose of study intervention)
    • AE of Special Interest (AESI)
    • Vaccine-Associated Enhanced Disease(VAED)
    • Serious adverse events (SAEs)

  2. Immunogenicity of MVC-COV1901 [ Time Frame: Day 1 to 28 days after second vaccination ]
    To evaluate the immunogenicity of MVC-COV1901, as compared to placebo, in terms of neutralizing antibody titers


Secondary Outcome Measures :
  1. Incidence of Adverse Event throughout study conduct (Safety of MVC-COV1901) [ Time Frame: Day 1 to 180 days after second vaccination ]

    To evaluate the safety of MVC-COV1901 over the study period in terms of the number and percentage of participants with the occurrence of:

    • >= Grade 3 AE
    • AE of Special Interest (AESI)
    • Vaccine-Associated Enhanced Disease(VAED)
    • Serious adverse events (SAEs)

  2. lot to lot consistency [ Time Frame: Day 1 to 28 days after second vaccination ]
    To evaluate the lot-to-lot consistency of MVC-COV1901 in participants of the ≥ 20 to < 65 years age group, the equivalence of the neutralizing antibody Geometric Mean Titer(GMT) among 3 different lots of MVC-COV1901


Other Outcome Measures:
  1. Incidence of confirmed COVID-19 cases (Efficacy of MVC-COV1901) [ Time Frame: Day 1 to 180 days after second vaccination ]

    To estimate the efficacy of MVC-COV1901, as compared to placebo, in the prevention of COVID-19 in terms of :

    • The number of laboratory-confirmed COVID-19 cases occurring ≥ 15 days after any dose of study intervention.
    • The number of laboratory-confirmed COVID-19 severe cases occurring ≥ 15 days after any dose of study intervention.

Inclusion Criteria:

  1. Male or female participant ≥ 20 to < 65 years, or ≥ 65 years of age at randomization.
  2. Healthy adults or adults with pre-existing medical conditions who are in stable condition. A stable medical condition is defined as disease not requiring significant change in therapy or hospitalization for worsening disease 3 months before enrollment and expected to remain stable for the duration of the study.
  3. Female participant must:

    1. Be either of non-childbearing potential, i.e. surgically sterilized (defined as having undergone hysterectomy and/or bilateral oophorectomy and/or bilateral salpingectomy; tubal ligation alone is not considered sufficient) or one year post-menopausal;
