Evaluating the Dose, Safety, Tolerability, and Immunogenicity of Mosaic Hexavalent Influenza Vaccine VRCFLUMOS0116-00-VP (FluMos-v2) With and Without ALFQ Adjuvant in Healthy Adults
NCT06863142 · View on ClinicalTrials.gov ↗
Study Summary
Background: Vaccines help the body learn to fight infections. Some vaccines are combined with adjuvants, which are added substances that make vaccines work better. FluMos-v2 is an experimental flu vaccine; ALFQ is an experimental adjuvant. Objective: To test FluMos-v2, with and without the ALFQ adjuvant, in healthy adults. Eligibility: Healthy adults aged 18 to 50 years. They must have received at least one flu vaccine from the 2020-21 season through the 2024-25 flu season. They must also agree not to receive the licensed 2025-26 flu vaccine. Design: Participants will have 12 clinic visits over 15 months. Participants will be screened. They will have a physical exam and blood tests. On 2 visits, about 4 months apart, participants will receive a vaccination. The shots will be given into the muscle of the upper arm. They will get a follow-up call the day after each shot. They will keep a daily diary for 7 days; they will record their temperature and any other symptoms they feel after each shot. All clinic visits will include collection of blood, saliva, and nasal secretions. If participants develop flu symptoms (such as fever, runny nose, sore throat), they will be asked to come to the clinic. About 2 weeks after each vaccination, participants may opt to undergo apheresis: Blood will be taken from the body through a needle inserted into one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be returned to the body through a needle in the other arm.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06863142
The ClinicalTrials.gov registry entry for NCT06863142 describes a study currently listed as recruiting. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 45 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Seasonal Influenza appearing as the primary indexed condition, and to 2 interventions — of which VRC-FLUMOS0116-00-VP is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06863142 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
