Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To collect the immunisation history of participants enrolled in a previous vaccine study (REC 09/H0604/107) in order to assess the influence of genetic variation on the level of immunity to routine immunisations.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Children aged 6 month to 13 years were enrolled in a study to compare the immunogenicity and safety of adjuvanted or non-adjuvanted influenza vaccines during the 2009 pandemic influenza season. Nine-hundred and forty-nine children were recruited from 5 UK centres: Oxford, Southampton, Bristol, Exeter, and London

In the previous study, DNA was collected when individuals provided appropriate consent, to explore the genetic determinants of responses to vaccination. Although, study participants consented for their medical records to be reviewed by members of the study team, and for these data as well as anonymised serum samples to be used in future research, routine immunisation histories were not collected before this study closed.

In this study we wish to collect the full vaccination history of participants, as this information will be extremely important in interpreting results. We propose sending a letter to parents/guardians informing them of the study and asking whether they are willing for members of the study team to approach their general practitioner or the child health computer system in order to retrieve these records. Immunisation histories will then be included with other non-identifiable information needed for analysis, and samples unlinked from personal identifiers prior to analysis.
