Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label study to evaluate the safety, reactogenicity, and immunogenicity of mRNA-1273 Severe Acute Respiratory Syndrome coronavirus (SARS-CoV-2) vaccine in adults with a kidney or liver solid organ transplant (SOT) and in healthy adult participants. The primary goal of the study is to evaluate the safety of mRNA-1273 and the serum antibody (Ab) responses obtained 28 days after the last dose of mRNA-1273.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

mRNA-1273

Part A: All participants (healthy participants and SOT participants) who were unvaccinated prior to enrollment will receive 2 intramuscular (IM) injections of 100 microgram (µg) mRNA-1273 on Day 1 and Day 29.

All SOT participants who were unvaccinated prior to enrollment will be offered the opportunity to receive a third primary dose of mRNA-1273 at Day 85 as per the emergency use authorization (EUA) Fact Sheet available at the time of protocol finalization.

SOT participants who were previously vaccinated with 2 doses of Moderna COVID-19 vaccine under the EUA prior to enrollment will receive Dose 3 on Day 1.

Part B: All eligible participants from Part A will be offered to receive a 100 µg booster dose of mRNA-1273 who are at least 4 months from the last dose. SOT recipients who completed primary COVID-19 vaccination series under EUA (outside of the mRNA-1273-P304 study) will receive a 100 µg booster dose on booster dose Day 1.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Is either a kidney or a liver transplant recipient who is at least 90 days after transplantation at the time of consent, and is either unvaccinated or previously vaccinated with 2 doses of Moderna COVID-19 vaccine who is at least 1 month after the second dose at the time of consent. Participants who received the 2 doses of Moderna COVID-19 vaccine before transplant are not eligible.
* Understands, agrees, and is able to comply with the study procedures and provides written informed consent.
* Received chronic immunosuppressive therapy for the prevention of allograft rejection for a minimum of 90 days before signing consent, including but not limited to: glucocorticoids (such as, prednisolone), immunophilin binding agents (such as, calcineurin inhibitors, mTOR inhibitors), or inhibitors of de novo nucleotide synthesis (such as, mycophenolic acid, mizoribine, leflunomide, azathioprine).
* For female participants of childbearing potential: negative pregnancy test, adequate contraception or has abstained from all activities that could result in pregnancy for at least 28 days prior to the first injection, agreement to continue adequate contraception or abstinence through 3 months following the second dose (Day 29) for those receiving 2-dose regimen and, through 3 months following the third dose (Day 85) for those receiving 3-dose regimen, and through 3 months following the third dose (Day 1) for those previously vaccinated SOT participants, and not currently breastfeeding.
* Is medically stable, according to investigator's judgment, during the 3 months before signing consent.


* In good general health without current or previous diagnosis of immunocompromising condition, immune-mediated disease, or other immunosuppressive condition, according to investigator assessment, at the time of consent, and has not been vaccinated with any COVID-19 vaccine at the time of consent.
* Understands, agrees, and is able to comply with the study procedures and provides written informed consent.
* For female participants of childbearing potential: negative pregnancy test, adequate contraception or has abstained from all activities that could result in pregnancy for at least 28 days prior to the first injection (Day 1), agreement to continue adequate contraception or abstinence through 3 months following the second injection (Day 29), and not currently breastfeeding.
* Is medically stable, according to investigator's judgment, during the 3 months before signing consent.


* Participants must have been previously enrolled in this study (mRNA-1273-P304), are actively participating in Part A, and at least 4 months from the last dose; or participant is either a kidney or a liver SOT recipient who is at least 90 days after transplantation at the time of consent and who completed primary vaccination series (3 doses for mRNA COVID-19 vaccine; 2 doses for non-mRNA COVID-19 vaccine or at least 1 dose of non-mRNA combined with 1 dose of mRNA COVID-19 vaccine) under the EUA who are at least 4 months from the last dose. All primary COVID-19 vaccination series must be completed after transplant.
* Female participants of childbearing potential may be enrolled in the study if the participant has a negative pregnancy test on the day of the first injection (booster dose Day 1).

Exclusion Criteria

* Has prior or planned administration of a coronavirus vaccine (for example, SARS-CoV-2 \[for unvaccinated participants only\], SARS-CoV, or MERS \[Middle East Respiratory Syndrome\] -CoV vaccine).
* Has current treatment with investigational agents for either prophylaxis against COVID-19 (for unvaccinated participants only) or treatment of COVID-19 (such as, anti-SARS-CoV-2 monoclonal antibodies).
* A history of more than one solid organ transplanted (such as, kidney and pancreas). A history of previous kidney or liver transplant is acceptable.
* Has received therapies that have depleting properties on T cells, B cells, and plasma cells (examples of depletional therapies include, but are not limited to, antithymocyte globulin \[ATG\], monoclonal antibodies, and proteosome inhibitors) within the last 3 months prior to enrollment.
* A history of biopsy-proven T-cell- or Ab-mediated rejection within 3 months of informed consent, or suspected active or chronic rejection according to the investigator's judgment.
* Has a known close contact with anyone with laboratory confirmed SARS-CoV-2 infection within 2 weeks to vaccine administration or known history of SARS-CoV-2 infection or positive SARS-CoV-2 test.
* Has a medical, psychiatric, or occupational condition that may pose additional risk as a result of participation or that could interfere with safety assessments or interpretation of results according to the investigator's judgment.
* Has a history of clinically relevant donor-specific Ab.
* Has a history of complications of immunosuppression
* Suspected clinically relevant active hepatitis, including viral hepatitis, according to the investigator's judgment
* Known human immunodeficiency virus (HIV) infection
* Has a history of a diagnosis or condition that, in the judgment of the investigator, may affect study endpoint assessment or compromise participant safety.
* Received any non-study vaccine within 28 days before or after any dose of vaccine (except for seasonal influenza vaccine, which is not permitted within 14 days before or after any dose of vaccine)
* Received intravenous blood products (red blood cells, platelets, immunoglobulins) within 3 months prior to Day 1.
* Participated in an interventional clinical study within 28 days prior to Day 0 or plans to donate blood products while participating in this study.
