| NCT07464314 | A Study on the Safety and Immune Response of Investigational mRNA Seasonal Flu/COVID-19 Combination Vaccine in Adults | PHASE1 | RECRUITING | 225 | — | — | Mar 9, 2026 | Jun 3, 2027 | Mar 27, 2026 | 2 | United States |
The assessed toxicity grades for laboratory value abnormalities will be defined as follows: Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe, and Grade 4 = Potentially life-threatening.
The solicited administration site AEs considered are pain, redness, swelling and lymphadenopathy.
The solicited systemic AEs considered are fever, headache, fatigue, myalgia, arthralgia and chills.
An unsolicited AE is an AE that was either not included in the list of solicited events or could be included in the list of solicited events but with an onset outside the specified period of follow-up for solicited events.
A SAE is an AE which results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or other situations that are considered serious per medical or scientific judgment.
The following events are considered as AESI in this study: severe hypersensitivity reactions within 24 hours after study intervention administration, Aminotransferase elevation; myocarditis/pericarditis within 6 weeks after study intervention administration and potential immune-mediated diseases (pIMDs).
A MAAE is an AE for which the participant received medical attention including any symptom or illness requiring hospitalization, or an emergency room visit, or visit to/by a healthcare professional.
