Post-authorisation Safety Study (PASS) of Influenza Vaccine in United Kingdom (UK)

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • All individuals (aged 6 months and above) who will receive seasonal influenza vaccination in the 9 GP practices between 1 September 2015 and 30 November 2015.
  • Pregnant women are also included in this study.

Exclusion criteria

  • Only registered patients who have explicitly opted out of data sharing will be excluded from the analysis.

Treatment and study plan

Vaccine safety surveillance

Other

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.

Other names: Data collection
