About this study

One-site dose sparing intradermal influenza vaccination in elderly had been studied but resulted in unsatisfactory outcomes. The investigators evaluate the safety and immunogenicity of the two-site intradermal injection of influenza vaccine containing all 6 and 12 micrograms of hemagglutinin antigen per strain (with 4/10th and 8/10th of a regular 15 microgram HA/strain intramuscular vaccine respectively) in elderly over 60 years of age. An influenza vaccine administered intramuscularly at the standard dose is used as the reference vaccine.

Read the detailed description

The subjects would be randomly divided into three groups of 60 subjects each. Group1 receives a single intramuscular dose of 0.5 ml of trivalent influenza vaccine, containing at least 15 microgram of hemagglutinin antigen per strain, Group II receives two-site intradermal dose of 0.1 ml each, containing at least 3 microgram of hemagglutinin antigen per strain per site and group III receives two-site intradermal dose of 0.2 ml each, containing at least 6 microgram of hemagglutinin antigen per strain per site.

What is being measured

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

  1. immunogenicity

    evaluate the immunogenicity of the two-site intradermal influenza vaccination containing all 6 and 12 micrograms of hemagglutinin antigen per strain (with 4/10th and 8/10th of a regular 15 microgram HA/strain intramuscular vaccine respectively) in elderly over 60 years of age , as measured by the titer of hemagglutination inhibition (HAI) antibodies, in order to determine whether it would meet the guidelines of the European Committee for Proprietary Medicinal Products (CPMP) for the annual relicensure of influenza vaccines

    Measured: 4 months

Secondary outcomes (2)
  1. comparison of the immunogenicity

    comparison of the immunogenicity of the two-site influenza vaccine administered intradermally as the above reduced dose with those of the reference influenza vaccine administered intramuscularly at the standard dose

    Measured: 4 months

  2. safety

    evaluate for number of participants with adverse effects:

    • systemic effects such as fever, headache, myalgia
    • local effects such as redness, swelling, induration and pain by giving diary card for each participant to record the data once daily for 1 week. (the investigators explain how to grade the redness (no/yes), swelling by measure, induration by measure, pain (no/yes))

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing seasonal influenza vaccine in people with Influenza, run by Queen Saovabha Memorial Institute at 1 site in Thailand.

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 2 inclusion and 9 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 6 Apr 2018. 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 Thailand. 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?

immunogenicity (time frame: 4 months). 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 6 Apr 2018.
