- the percentage of subjects achieving seroconversion1 or significant increase in antibody titer2 at Day 14 an at Day 21, as determined by HI;
- the percentage of subjects achieving a titer ≥40 at Day 0, at Day 14 and at Day 21 as determined by HI.
Measured: 21-28 days following vaccination
Secondary outcomes (1)

Questions about this trial
What is this clinical trial studying?
A study testing Vaccination with FAB-3511, Vaccination with FAB-6011 and Vaccination with FAB-9011 in people with Influenza, run by Fluart Innovative Vaccine Ltd, Hungary at 4 sites in Hungary.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 May 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Hungary. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
MEASURES OF IMMUNOGENICITY (time frame: 21-28 days following vaccination). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2012.
