Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study includes two cohorts. Cohort 1 will provide rapid information about the immunogenicity of mRNA-1273.351 in a previously vaccinated group. This cohort can inform near term public health decisions if the variant virus becomes more widespread. Cohort 2 will evaluate different strategies for generation of cross protective immune responses in a naïve population. This cohort will take longer to provide information on the immunogenicity of mRNA-1273.351, but is important to inform future public health strategies. Cohort 1 will include approximately 60 subjects 18 years of age and older who received two vaccinations of mRNA-1273 at dosages of 50 mcg, 100 mcg, or 250 mcg in the Phase 1 clinical trial (DMID 20-0003). Subjects in Cohort 1 will receive a single intramuscular (IM) injection of the designated vaccine and will be followed through 12 months after vaccination. Follow-up visits will occur on Days 8, 15, and 29, as well as 3, 6, and 12 months after the vaccination. Cohort 2 will include approximately 150 participants 18 through 55 years of age who have not received a COVID-19 vaccine, have no known history of COVID-19 or SARS-CoV-2 infection, and do not have underlying conditions that are associated with an increased risk of severe illness from SARS-CoV-2 infection. Enrollment may close before the full 150 participants based on estimates on the timing of immunogenicity results and the need to inform public health decisions. They will be randomly assigned to one of 8 treatment arms and will receive 2 or 3 IM injections of the vaccine and followed through 12 months after the last vaccination. Follow-up visits will occur 7, 14, and 28 days after each vaccination, as well as 3, 6 and 12 months post the last vaccination.
The primary objective is to evaluate the safety and reactogenicity of mRNA-1273 and mRNA-1273.351 vaccines, in naïve and previously vaccinated individuals.

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Be able to understand and agrees to comply with planned study procedures and be available for all study visits.
3. Agrees to the collection of venous blood per protocol.
4. Cohort 1: previously received 2 doses of mRNA-1273 intramuscular (IM) as part of DMID 20-0003.
5. Cohort 1: Male or non-pregnant female, \>/= 18 years of age at time of enrollment. Cohort 2: Male or non-pregnant female, 18 through 55 years of age at time of enrollment.
6. Women of childbearing potential\* must agree to practice abstinence or use at least one acceptable primary form of contraception.\*\*, \*\*\* Note: These criteria are applicable to females in a heterosexual relationship and child-bearing potential (i.e., the criteria do not apply to subjects in a same sex relationship).
\* Not of childbearing potential - post-menopausal females (defined as having a history of amenorrhea for at least one year) or a documented status as being surgically sterile (hysterectomy, bilateral oophorectomy, tubal ligation/salpingectomy, or Essure(R) placement).
\*\* Acceptable forms of primary contraception include monogamous relationship with a vasectomized partner who has been vasectomized for 180 days or more prior to the subject's first vaccination, intrauterine devices, birth control pills, and injectable/implantable/insertable hormonal birth control products.
\*\*\* Must use at least one acceptable primary form of contraception for at least 30 days prior to the first vaccination and at least one acceptable primary form of contraception for 60 days after the last vaccination.
7. In good health.\*
\* As determined by medical history and physical examination to evaluate acute or ongoing chronic medical diagnoses/conditions that have been present for at least 90 days, which would affect the assessment of safety of subjects. Chronic medical diagnoses/conditions should be stable for the last 60 days (no hospitalizations, emergency room, or urgent care for condition or need for supplemental oxygen). This includes no change in chronic prescription medication, dose, or frequency as a result of deterioration of the chronic medical diagnosis/condition in the 60 days before enrollment. Any prescription change that is due to change of health care provider, insurance company, etc., or done for financial reasons, and in the same class of medication, will not be considered a deviation of this inclusion criterion. Any change in prescription medication due to improvement of a disease outcome or for dose optimization, as determined by the participating site PI or appropriate sub-investigator, will not be considered a deviation of this inclusion criterion. Subjects may be on chronic or as needed (prn) medications if, in the opinion of the participating site PI or appropriate sub-investigator, they pose no additional risk to subject safety or assessment of reactogenicity and immunogenicity, and do not indicate a worsening of medical diagnosis/condition. Similarly, medication changes subsequent to enrollment and study vaccination are acceptable provided the change was not precipitated by deterioration in the chronic medical condition, and there is no anticipated additional risk to the subject or interference with the evaluation of responses to study vaccination.
8. Oral temperature is less than 100.0 degrees Fahrenheit (37.8 degrees Celsius).
9. Must agree to have samples stored for secondary research.
10. Agrees to adhere to Lifestyle Considerations throughout study duration.
11. Must agree to refrain from donating blood or plasma during the study (outside of this study).
Exclusion Criteria

3. Female subject who is breastfeeding.
4. Has any medical disease or condition that, in the opinion of the participating site PI or appropriate sub-investigator, precludes study participation.\*
\* Including acute, subacute, intermittent or chronic medical disease or condition that would place the subject at an unacceptable risk of injury, render the subject unable to meet the requirements of the protocol, or may interfere with the evaluation of responses or the subject's successful completion of this trial.
5. Presence of self-reported or medically documented significant medical or psychiatric condition(s).\*
\* Significant medical or psychiatric conditions include but are not limited to: Respiratory disease (e.g., chronic obstructive pulmonary disease \[COPD\], asthma) requiring daily medications currently or any treatment of respiratory disease exacerbations (e.g., asthma exacerbation) in the last 5 years.

\* An acute illness which is nearly resolved with only minor residual symptoms remaining is allowable if, in the opinion of the participating site PI or appropriate sub-investigator, the residual symptoms will not interfere with the ability to assess safety parameters as required by the protocol.
7. Has participated in another investigational study involving any investigational product\* within 5 half-lives before the first vaccine administration.
\* study drug, biologic or device.
8. Currently enrolled in or plans to participate in another clinical trial with an investigational agent\* that will be received during the study-reporting period.\*\*
