Brief Summary:

The purpose of this study is to evaluate the safety and efficacy of mRNA COVID-19 vaccines in:

• People with prior COVID-19 (SARS-CoV-2 infection) who were in the ACTIV-2/A5401 study.

And

• People who have never had COVID-19 (SARS-CoV-2 infection).


Condition or disease Intervention/treatment Phase
Covid19 SARS-CoV2 Infection Biological: Moderna mRNA-1273 COVID-19 vaccine Biological: Community-provided mRNA-based COVID-19 vaccine Biological: Community-Provided Moderna mRNA-1273 COVID-19 Vaccine Phase 4

Detailed Description:
This study is for people who had COVID-19 and participated in ACTIV-2/A5401 and received either experimental treatment, a standard of care COVID-19 treatment, or placebo. This study is also for people who have not previously had a COVID-19 infection. The study is designed to evaluate how the immune system responds to mRNA-COVID-19 vaccines in these participants. The safety of mRNA COVID-19 vaccines in persons with prior COVID-19 who did and did not receive prior experimental treatment for COVID-19 will be explored. Prior infection with or without treatment could increase, decrease, or have no significant effect on the response to mRNA COVID-19 vaccines, as well as the risk of side effects from these vaccines. Immune responses of participants who have not previously been infected with COVID-19 will be compared to those who have previously had COVID-19.

Arm Intervention/treatment
Experimental: mRNA-based COVID-19 vaccine
To be administered intramuscularly (IM) at Day 0 and Day 28.
Biological: Moderna mRNA-1273 COVID-19 vaccine
100 µg (0.5 mL) to be administered intramuscularly (IM) at Day 0 and Day 28.

Biological: Community-provided mRNA-based COVID-19 vaccine
Two dose series.

Biological: Community-Provided Moderna mRNA-1273 COVID-19 Vaccine
Participants will receive (or have recently received) a community-provided Moderna mRNA-1273 COVID-19 vaccine at (or before) Day 0 and study-provided Moderna mRNA-1273 COVID-19 vaccine, 100 µg (0.5 mL) to be administered intramuscularly (IM) at at least 28 days apart.




Primary Outcome Measures :
  1. Neutralizing antibody (NAb) level at least [ Time Frame: At least 56 days after the first dose of the study- or community-provided vaccine ]

Secondary Outcome Measures :
  1. Relative pre-vaccine to post-vaccine change in NAb response [ Time Frame: The pre-vaccine NAb measurement will be obtained before the first dose of the vaccine, and the post-vaccine measurement will be obtained at least 56 days after the first dose of the vaccine. ]
    Defined as the ratio of post-vaccine level/pre-vaccine level.

  2. New Grade 3 or higher AE, or SAE, or AE leading to change or discontinuation in vaccine receipt [ Time Frame: From first dose of the mRNA-based COVID-19 vaccine and through 56 days after the first dose of vaccine. ]
  3. Proportion of participants with Grade 1 or higher allergic reaction from first dose of the mRNA-based COVID-19 vaccine. [ Time Frame: Through the visit 56 days after the first dose of the vaccine ]
  4. Proportion of participants with Grade 2 or higher injection site reaction from first dose of the mRNA-based COVID-19 vaccine. [ Time Frame: Through the visit 56 days after the first dose of the vaccine ]
  5. CD4+ T cell response to SARS-CoV-2 spike protein [ Time Frame: At the visit 56 days after the first dose of the vaccine ]
  6. CD8+ T cell response to SARS-CoV-2 spike protein [ Time Frame: At the visit 56 days after the first dose of the vaccine ]
  7. IgG serologic response to SARS-CoV-2 spike protein at receptor binding domain (RBD) and N terminal domain (NTD) and Matrix (M) protein. [ Time Frame: At the visit 56 days after the first dose of the vaccine ]
  8. IgM serologic response to SARS-CoV-2 spike protein at receptor binding domain (RBD) and N terminal domain (NTD) and Matrix (M) protein. [ Time Frame: At the visit 56 days after the first dose of the vaccine ]
  9. Flow cytometry of PBMC for markers of exhaustion on B and T cells [ Time Frame: At study entry/Day 0 and 56 days after the first vaccine dose. ]
  10. Relative pre-vaccine to post-vaccine change in NAb response [ Time Frame: The pre-vaccine NAb measurement will be obtained before the first dose of the vaccine, and the post-vaccine measurement will be obtained at least 56 days after the first dose of the vaccine. ]
    Defined as the ratio of post-vaccine level/pre-vaccine level by received vaccine, i.e., Moderna versus Pfizer.
