What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The immunogenicity of 2013-2014 seasonal trivalent vaccine (TIV) in adults and seniors

    To evaluate the immune responses to each antigen of the 2013-2014 seasonal TIV in adults and seniors by detection of hemagglutination inhibition (HI) antibody titer

    Measured: 21 days after vaccination

Secondary outcomes (2)
  1. The incidences of adverse events (AEs) in infants, adults and seniors

    After each injection, a 30-minute safety observation was conducted immediately, and the body temperature, occurrence of solicited local and general AEs within 72 hours were collected. Unsolicited AEs of adults and seniors were collected until day 21, and those of infants were collected until day 35. Each AE case was reviewed by the investigator to determine whether or not it was an adverse reaction (related to the vaccination).

    Measured: Day 0 - day 35

  2. The cross-reactivity of 2013-2014 seasonal TIV in adults and seniors against influenza B Victoria lineage virus and the avian influenza A(H7N9) virus

    To evaluate the cross-reactivity of 2013-2014 seasonal TIV in adults and seniors against influenza B Victoria lineage virus (not in the vaccine formulation) and the avian influenza A(H7N9) virus by detection of HI antibody titer

    Measured: 21 days after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing trivalent seasonal influenza vaccine in people with Influenza, run by Sinovac Biotech Co., Ltd at 1 site in China.

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 8 inclusion and 32 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 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

The immunogenicity of 2013-2014 seasonal trivalent vaccine (TIV) in adults and seniors (time frame: 21 days after vaccination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02269852, which also lists 1 linked publication.

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 Sep 2015.
