Outcome Measures

Primary Outcomes (1)

  • The correlation between humoral immune response and reactogenicity after vaccination

    The correlation between humoral immune response and reactogenicity after vaccination

    The correlation between reactogenicity after dose 1 and immunogenicity at T1 (28 days after dose 1 prior to the 2nd dose) and T2 (28 days after dose 2); the correlation between reactogenicity after vaccine dose 2 and immunogenicity at T2

Secondary Outcomes (4)

  • anti-SARS-CoV-2 antibody

    before vaccination (T0), 28 days after the first dose prior to the second dose (T1), and 28 days after the second dose (T2)

  • neutralizing antibody titer

    before vaccination (T0), 28 days after the first dose prior to the second dose (T1), and 28 days after the second dose (T2)

  • reactogenicity after vaccination

    Seven days after each dose of vaccine

  • Long-term persistence of anti-SARS-CoV-2 antibody and neutralizing antibody titer

    At 3 months and 6 months after dose 1

Interventions

two doses of mRNA-1273 vaccine at 28-day intervals
