Summary
This study is a prospective, randomized clinical trial. During this study, participants will be randomly assigned to receive quadrivalent inactivated influenza vaccine (IIV4) and mRNA COVID-19 vaccine either simultaneously or sequentially, 7-14 days apart. Persons in the simultaneous group will receive mRNA COVID-19 and IIV4 at Visit 1 (Day 1) and a saline placebo injection at Visit 2. Persons in the sequential group will receive mRNA COVID-19 vaccine and a saline placebo at Visit 1 (Day 1) and IIV4 injection at Visit 2. For participants receiving their primary dose series, a second dose of mRNA COVID-19 vaccine will be administered either 3 to 8 weeks or 4 to 8 weeks following the first dose, depending upon the mRNA COVID-19 vaccine provided. For those receiving a booster dose of mRNA COVID-19 only a single mRNA COVID-19 will be received in this study. Solicited symptoms of reactogenicity and adverse events will be assessed on vaccination day and daily during the 7 days following each Vaccination Visit using either electronic or paper symptoms diaries, depending on study participant preference. Quality of life data will be collected using electronic or paper diaries on day of Vaccination Visit 1 and daily during the 7 days following the visit. Serious adverse events and adverse events of special interest will be collected throughout the duration of the study. Participants are followed through Day 121. Serum samples from participants will be collected for determination of SARS-CoV-2 seropositivity at baseline. Serum samples will be taken throughout the study to determine IIV4 and COVID-19 vaccine immunogenicity and for potential future studies.
Eligibility Criteria
Inclusion Criteria
- Persons aged ≥5 years if receiving primary two-dose mRNA COVID-19 vaccine series or persons aged ≥12 years if receiving a booster mRNA COVID-19 vaccine dose according to FDA authorization or approval and ACIP recommendation. Note: receipt of an mRNA COVID-19 vaccine within 8 hours of enrollment is permitted
*Individuals age 5-11 receiving a booster may be enrolled in the event a booster for individuals age 5-11 is authorized or approved and recommended by the ACIP.
- English or Spanish literate
- Intention of receiving influenza vaccine and COVID-19 vaccine based on ACIP-CDC guidelines
- Willing to provide written informed consent
- Intention of being available for entire study period and complete all relevant study procedures, including follow-up phone calls and clinic visits
Exclusion Criteria
- Currently pregnant, planning to become pregnant within the first three months of the study per participant self-report or likely to be pregnant per screening criteria as defined in Section 5.1 at Visit 1
- Prior receipt of IIV4 during the respective influenza season in which they are being enrolled
- 200 within 6 months before enrollment, and on stable antiretroviral therapy for at least 6 months
- Has known hepatitis B (HBV) or hepatitis C (HBC). Stable HBV or HBC are permitted per the following parameters:
- If known HBV: confirmed inactive chronic HBV infection: HBsAg present for ≥6 months and HBeAg negative, anti-HBe positive; serum HBV DNA <2000 IU/mL; persistently normal ALT or AST levels; in those who had liver biopsy, findings that confirm absence of significant necroinflammation
- If known HCV: evidence of sustained virological response for ≥12 weeks after treatment or without evidence of HCV RNA viremia (undetectable HCV RNA)
- Use of oral, parenteral, or high-dose inhaled glucocorticoids*
*For definition of high-dose inhaled glucocorticoids, reference Appendix B.
- History of Guillain-Barré syndrome
- Prior enrollment in this study during the 2021-22 flu season
- Anyone who is already enrolled or plans to enroll in another clinical trial with an investigational product during the study period.*
*Per protocol, co-enrollment in observational or behavioral intervention studies are permitted at any time. An investigational product may be permitted for therapy of an illness condition that occurs during the study period e.g. COVID-19 illness.
- Hearing loss determined by the investigators to prevent successful communication over the phone
- History of myocarditis or pericarditis
- History of multisystem inflammatory syndrome in children (MIS-C) or adults (MIS-A).
- Has injury or other reason why deltoid site on both arms cannot be used for vaccinations.
- Any condition which, in the opinion of the investigators, may pose a health risk to the subject or interfere with the evaluation of the study objectives.
- Anyone who is a relative of any research study personnel.
- Anyone who is an employee of any research study personnel.
