PHASE4

Brief Summary

The purpose of this study is to characterize the immune response to the FDA-approved mRNA-based RSV vaccine in adults ≥60 years of age, using a systems biology approach. The study aims to generate hig...

Detailed Description

Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract disease (LRTD) in older adults and individuals with chronic comorbidities. In response to this burden, several RSV vacci...

Eligibility Criteria

Inclusion

  • Adults ≥60 years of age at the time of enrollment.
  • Able and willing to provide written informed consent.
  • Eligible for receipt of an FDA-approved RSV vaccine (MRESVIA) per Advisory Committee on Immunization Practices (ACIP)/Centers for Disease Control and Prevention (CDC) guidelines.
  • Available for all study visits and procedures, including follow-up through Day 180.
  • Willing to allow access to prior RSV vaccination history (if applicable) for eligibility verification

Exclusion

  • History of severe allergic reaction (e.g., anaphylaxis) to any prior vaccines or any component of the MRESVIA vaccine, including polyethylene glycol (PEG), the amino lipid SM-102 (SM-102), or other listed excipients.
  • Acute illness or fever (temperature ≥100.4°F) at the time of vaccination (participant may be rescheduled).
  • Immunocompromising conditions, including:
  • Current cancer chemotherapy or immunosuppressive therapy.
  • History of hematologic malignancies or other immune-mediated diseases that would interfere with vaccine response.
  • Known or suspected HIV infection with cluster of differentiation 4 (CD4) count \<200 or uncontrolled viremia.
  • Clinically significant cardiac, pulmonary, renal, hepatic, or neurological disease that, in the opinion of the investigator, would preclude participation or confound interpretation of immune data.
  • Uncontrolled autoimmune disorder.
  • Current use of systemic corticosteroids equivalent to ≥20 mg prednisone daily for more than 14 consecutive days in the past month.
  • History of Guillain-Barré Syndrome or other demyelinating neurological disorders.
  • History of myocarditis, pericarditis, or myopericarditis within the last 2 months.
  • Any bleeding disorder that poses a risk for venipuncture or vaccination complications.
  • Participation in another clinical trial involving an investigational agent within 30 days of enrollment.
  • Receipt or plan receipt of vaccines in the past an upcoming 28 days.
  • Prior receipt of any RSV vaccine.
  • Receipt of blood products or immune globulin within the prior 3 months.
  • History of excessive alcohol consumption or drug use, or psychiatric/social/occupational conditions that may interfere with study compliance.
  • Any other condition that, in the opinion of the investigator, may interfere with study conduct or participant safety.
