About this study

Official title: European Medicines Agency (EMA) Post-authorisation Safety Study of Influenza Vaccine

The purpose of this study is to conduct a pilot study to explore the potential use of routinely collected data in General Practitioner (GP) practices to conduct enhanced safety surveillance of seasonal influenza vaccines in the UK, as recommended in the EMA interim guidance on enhanced safety surveillance for seasonal influenza vaccines in the EU.

Read the detailed description

Data routinely collected as part of clinical consultations in primary care will be extracted from nine General Practitioner (GP) practices in order to estimate medically attended Adverse Events of Interest (AEIs), for people who have received an influenza vaccine. This study will also actively follow patients who were exposed to seasonal influenza vaccination for 7 days in three of the nine GP practices using a customised card-based adverse drug reaction reporting system, in order to determine whether a more active approach to surveillance can capture higher rates of AEIs.

    Also called Data collection

    Extraction of routinely collected primary care data from nine GP practices and an active surveillance approach in 3 of the 9 GP practices, by using an existing card-based ADR reporting system (MHRA Yellow Card), to estimate proportions of AEIs among seasonal influenza-vaccinated individuals.

What is being measured

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

  1. Number of patient counts of the total registered patients vaccinated by age strata, reported weekly and cumulatively by brand (also indicating those for whom brand data are unavailable)

    Measured: Up to 3 months (between 1 September 2015 and 30 November 2015)

  2. Proportions of total registered patients vaccinated by age strata, reported weekly and cumulatively by brand (also indicating those for whom brand data are unavailable)

    Measured: Up to 3 months (between 1 September 2015 and 30 November 2015)

  5. Number of patient counts of the vaccinated patients with reported endpoints of interest by age strata, reported weekly and cumulatively by brand (also indicating those for whom brand data are unavailable)

    • Presentation with fever or other febrile illness, - Presentation related to local reaction, - Presentation related to general reaction (fatigue, myalgia, etc.), - All other presentations that could plausibly be related to vaccination.

    Measured: Up to 3 months (between 1 September 2015 and 30 November 2015)

  6. Proportions of vaccinated patients with reported endpoints of interest by age strata, reported weekly and cumulatively by brand (also indicating those for whom brand data are unavailable)

    • Presentation with fever or other febrile illness, - Presentation related to local reaction, - Presentation related to general reaction (fatigue, myalgia, etc.), - All other presentations that could plausibly be related to vaccination.

    Measured: Up to 3 months (between 1 September 2015 and 30 November 2015)

  7. Number of patient counts of the vaccinated patients with reported endpoints of interest by co-morbidity, reported weekly and cumulatively by brand (also indicating those for whom brand data are unavailable)

    • Presentation with fever or other febrile illness, - Presentation related to local reaction, - Presentation related to general reaction (fatigue, myalgia, etc.), - All other presentations that could plausibly be related to vaccination.

    Measured: Up to 3 months (between 1 September 2015 and 30 November 2015)

  8. Proportions of vaccinated patients with reported endpoints of interest by co-morbidity, reported weekly and cumulatively by brand (also indicating those for whom brand data are unavailable)

    • Presentation with fever or other febrile illness, - Presentation related to local reaction, - Presentation related to general reaction (fatigue, myalgia, etc.), - All other presentations that could plausibly be related to vaccination.

    Measured: Up to 3 months (between 1 September 2015 and 30 November 2015)

  9. Incidence rates for the 5 most frequently reported AEs reported alongside those available in the literature from a similar population (vaccinated or general population if vaccinated not available) within the same risk period and stratified by age.

    Measured: Up to 3 months (between 1 September 2015 and 30 November 2015)

Questions about this trial

What is this clinical trial studying?

An observational study of Influenza, run by GlaxoSmithKline at 1 site in United Kingdom.

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 1 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 12 Feb 2016. 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 United Kingdom. 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?

Number of patient counts of the total registered patients vaccinated by age strata, reported weekly and cumulatively by brand (also indicating those for whom brand data are unavailable) (time frame: Up to 3 months (between 1 September 2015 and 30 November 2015)). The study lists 8 primary outcomes in all. 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 12 Feb 2016.
