Brief Summary
The purpose of this study is to assess the serologic and cell-mediated immune response to licensed live attenuated influenza vaccine (LAIV) and inactivated influenza vaccine (IIV) in children 5-17 years old. The effects of prior infection and or prior season vaccination will be examined. Children will be followed during the influenza season to identify laboratory-confirmed influenza (i.e. vaccine failure).

Study Arms (2)
LAIV 2014-15
OTHERWill receive LAIV this year. Includes 5-8 year olds and approximately half of the 9-17 year olds. Prior history includes vaccine failures, vaccinated/uninfected and unvaccinated/uninfected last year. PBMC available for those who were infected last year, all ages.
IIV 2014-15
OTHERWill receive IIV this year. Includes only 9-17 year olds (unless shortages of LAIV encountered). Prior history includes vaccine failures, vaccinated/uninfected and unvaccinated/uninfected last year. PBMC available for those who were infected last year, only 9-17 year olds.
Interventions
Licensed and approved Live Attenuated Influenza Vaccination (LAIV) will be preferentially given to all children aged 5-8 years old as recommended by Advisory Committee on Immunization Practices. A modified randomization scheme in which every other child aged 9-17 years enrolled in the study will be given LAIV will be used. The rest of the children aged 9-17 years old will receive IIV.
A modified randomization scheme in which every other child aged 9-17 years enrolled in the study will be given IIV will be used. The rest of the children 9-17 years old will receive LAIV. \[Note: Although we do not anticipate exhausting the supply of LAIV, should this occur, children aged 5-8 will be offered IIV as it is also approved in this age group and should be used if LAIV is unavailable.\]
Eligibility Criteria
You may qualify if:
- Aged 5-17 years for the duration of the study period (Sept 1, 2014-Apr 1, 2015)
- Enrolled in either the immune response study or the vaccine effectiveness study conducted at the site in the 2013-14 influenza season
- If enrolled in the vaccine effectiveness study the previous season must have either been vaccinated and infected with influenza or unvaccinated and uninfected with influenza
You may not qualify if:
- Children with contraindications to either the quadrivalent live attenuated influenza vaccine or to the trivalent inactivated influenza vaccine will be excluded.
- Anyone unwilling or unable to complete all required study activities including informed consent
- Subjects who already received the influenza vaccine for the 2014-15 season
