Description of intervention(s) / exposure
This study aims to survey 400 parents for their recall of febrile and other reactions following their child’s vaccination with the 2011 seasonal influenza vaccine manufactured by GSK (Fluarix).
This will be a retrospective telephone survey of parents of infants and children, who received 2011 Fluarix influenza vaccine, and will be conducted by the practice nurses, in the general practice who administered the vaccine to the infants or children.
Recruitment is expected to take 2 months, or until 400 survey have been received which ever is the first.

Outcomes
Primary outcome [1] 269425 0
The primary objective of this study will be to determine the rates of febrile events in young children aged 6 months to 8 years inclusive within 24 hours of receipt of any dose of 2011 Fluarix (2011 seasonal influenza vaccine manufactured by GSK).
Parental recall to questions on the survey instrument will be recorded
Recall of fever (Yes/No) if yes did the fever occur between 1-4 hrs, 5-8 hrs, 9-24 hrs or after 24hrs
Was the childs temperature measured (Yes/No) if yes what was the measured temperature. Fever, endogenous elevation of at least one measured body temperature of 38C
Were there any other reactions (Yes/No) These will be coded as myalgia, arthralgia, malaise and headache etc.
Was anti-fever medicine given (Yes/No) if yes was it given before or after vaccination
Did you need to call or see a doctor (Yes/No) if yes who, where and why
Timepoint [1] 269425 0

Secondary outcome [1] 287606 0
Evaluate the reactogenicity of Fluarix, in young children aged 6 months to 8 years inclusive, associated with febrile AEs after any dose. Descriptive statistics will describe all baseline variables and key outcome variables and paired t-tests used to evaluate per person changes in temperature (temperatures will be characterised by reporting of mean, median and ranges). Incidence rates for febrile AEs will be further characterised by assessment of severity (by temperature grades of febrile AEs (38C, 39C and 40C), whether the febrile AE was medically attended, and any associated seizures (according to Brighton Collaboration seizure definitions). Patterns of febrile AEs with associated symptoms in other organ systems will also be characterised by incidence rates, with exploration of the associated severity of fever by major symptom clusters.
