Summary
This trial studies the safety and effectiveness of a new vaccine in healthy adults aged 18-49. A separate group of 10 participants will receive licensed quadrivalent influenza vaccine. Up to 10 subjects per dose group will be enrolled.
Who is the study for?
Healthy adults aged 18-49, with stable blood pressure and pulse, a BMI of 18 to <35 kg/m^2, who've had an influenza vaccine in the last five seasons. Women must not be pregnant or breastfeeding and agree to contraception. Excludes those with immune conditions, recent drug abuse, psychiatric hospitalization, or certain medication use.
What is being tested?
The trial is testing a new mRNA-LNP flu vaccine called H1ssF_3928 at different doses (10 mcg, 25 mcg, and 50 mcg) against a licensed quadrivalent flu vaccine. It's an open-label study where healthy volunteers receive one dose intramuscularly to evaluate safety and immune response.
What are the potential side effects?
Potential side effects may include typical reactions at the injection site like pain or swelling, general symptoms such as fever or fatigue after vaccination. Since it's a Phase I trial focused on safety, close monitoring for any adverse events will occur.

Experimental Treatment
Active Control
Group I: Arm 4, Optimal DoseExperimental Treatment2 Interventions
10 healthy adult volunteer subjects from 18-49 years of age will receive the selected optimal dose of the H1ssF_3928 mRNA Vaccine, administered intramuscularly once. The optimal dosing group will be selected based on safety outcomes from the 10 mcg, 25 mcg, and 50 mcg dosing groups. For the optimal dose, the highest dose with no identified safety concerns as determined by the Safety Review Committee (SRC) will be selected. N =10
Group II: Arm 3, High DoseExperimental Treatment2 Interventions
10 healthy adult volunteer subjects from 18-49 years of age are split into two subgroups. The sentinel subgroup includes 2 vaccine recipients who will receive 50 mcg of the H1ssF_3928 mRNA Vaccine, administered intramuscularly once. The sentinel subgroup is observed for 8 days to monitor any early vaccine related adverse events. After the observation period, the remaining participants will receive the same dosage, 50 mcg of the H1ssF 3928 mRNA vaccine administered intramuscularly once. N = 10
Group III: Arm 2, Medium DoseExperimental Treatment2 Interventions
10 healthy adult volunteer subjects from 18-49 years of age are split into two subgroups. The sentinel subgroup includes 2 vaccine recipients who will receive 25 mcg of the H1ssF_3928 mRNA Vaccine, administered intramuscularly once. The sentinel subgroup is observed for 8 days to monitor any early vaccine related adverse events. After the observation period, the remaining participants will receive the same dosage, 25 mcg of the H1ssF 3928 mRNA vaccine administered intramuscularly once. N = 10
Group IV: Arm 1, Low DoseExperimental Treatment2 Interventions
10 healthy adult volunteer subjects from 18-49 years of age are split into two subgroups. The sentinel subgroup includes 2 vaccine recipients who will receive 10 mcg of the H1ssF_3928 mRNA Vaccine, administered intramuscularly once. The sentinel subgroup is observed for 8 days to monitor any early vaccine related adverse events. After the observation period, the remaining participants will receive the same dosage, 10 mcg of the H1ssF 3928 mRNA vaccine administered intramuscularly once. N = 10
Group V: Arm 5, IIV4Active Control1 Intervention
10 healthy adult volunteer subjects from 18-49 years of age will receive licensed Quadrivalent Influenza Vaccine (IIV4), administered intramuscularly once. Subjects receiving IIV4 will be followed for safety, but only their immune responses will be compared to those of participants receiving H1ssF_3928 mRNA Vaccine. N=10
