About this study

Official title: Enhanced Passive Safety Surveillance of VaxigripTetra® (Quadrivalent Inactivated Split Virion Influenza Vaccine, Intramuscular Route) and Efluelda® (Quadrivalent Inactivated Split Virion Influenza Vaccine, Intramuscular Route) Vaccines in Europe During the Influenza Season 2021/22.

The primary objective of the study is to estimate the reporting rate of suspected Adverse Drug Reactions (ADRs) occurring within 7 days following routine vaccination with VaxigripTetra® and Efluelda®, respectively, during the Northern Hemisphere (NH) influenza season 2021/22.

The secondary objectives of the study are:

  • To estimate the reporting rates of suspected ADRs occurring within 7 days following routine vaccination with VaxigripTetra® according to the pre-defined age groups.
  • To estimate the reporting rates of serious suspected ADRs after vaccination with VaxigripTetra®, and Efluelda®, respectively, at any time following vaccination, within the Enhanced Passive Safety Surveillance (EPSS) period.
  • To compare vaccinees' reporting rates of suspected ADRs observed during the NH influenza season 2021/22.

Efluelda®Participant vaccinated with Efluelda® as per routine clinical practice

What is being measured

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

  1. Vaccinees' reporting rate following routine vaccination with VaxigripTetra® and Efluelda®

    The vaccinees' reporting rate is expressed as the percentage of vaccinees who reported at least one suspected ADR among the distributed vaccination cards

    Measured: Within 7 days after vaccination

  2. ADR reporting rate following routine vaccination with VaxigripTetra® and Efluelda®

    The ADR reporting rate is expressed as the percentage of suspected ADRs among the distributed vaccination cards

    Measured: Within 7 days after vaccination

Secondary outcomes (4)
  1. ADR reporting rate according to age group

    Measured: Within 7 days after vaccination

  2. Vaccinees' reporting rate according to age group

    Measured: Within 7 days after vaccination

  3. Vaccinees' reporting rate of serious suspected ADRs at any time following vaccination within the EPSS period

    Serious suspected ADRs will be collected from vaccination up to the end of data collection. Data collection ends when 1000 vaccination cards have been distributed (per vaccine brand) plus 2 weeks or 2 months following the first vaccination, whichever comes first.

    Measured: From vaccination to end of data collection (maximum 2 months following first vaccination)

  4. Serious suspected ADR reporting rate at any time following vaccination within the EPSS period

    Serious suspected ADRs will be collected from vaccination up to the end of data collection. Data collection ends when 1000 vaccination cards have been distributed (per vaccine brand) plus 2 weeks or 2 months following the first vaccination, whichever comes first.

    Measured: From vaccination to end of data collection (maximum 2 months following first vaccination)

Questions about this trial

What is this clinical trial studying?

An observational study of Influenza (Healthy Volunteers), run by Sanofi Pasteur, a Sanofi Company at 15 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 24 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in Germany, Finland. 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?

Vaccinees' reporting rate following routine vaccination with VaxigripTetra® and Efluelda® (time frame: Within 7 days after vaccination). The study lists 2 primary outcomes in all. 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 NCT05078060, 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 24 Mar 2023.
