Summary

The purpose of this study is to evaluate the possibility that giving an increased dose of flu vaccine to children 6 through 35 months of age will improve protection against influenza without increasing side effects. Investigators will evaluate the body's response to the vaccine. Male and female participants' ages 6-35 months, who have never received flu vaccine, and those ages 12-35 months, who have been previously vaccinated, will participate in the study for about 7 months. Vaccine naïve study participants will receive two doses of flu vaccine, either the 0.25 mL dose (Group 1) or 0.5 mL dose (Group 2). Previously vaccinated subjects will receive one dose of flu vaccine, either the 0.25 mL dose (Group 1) or 0.5 mL dose (Group 2). Study procedures include physical examination, memory aids, blood sampling and a follow-up phone call about 6 months after the last vaccine dose.

Conditions

Interventions

BIOLOGICAL

Trivalent Inactivated Influenza Vaccine

Either a standard pediatric dose (0.25 ml) or a larger dose (0.5 ml) of Trivalent Inactivated Influenza Vaccine (TIV) (Fluzone®) administered intramuscularly (IM) in the thigh with a 25 gauge 1 inch needle. Naive cohort (enrolled over two influenza seasons (2010-11 and 2011-12)) will receive vaccine in two IM doses 28-42 days apart, Fully Primed cohort (enrolled in one influenza season (2010-11)) will receive vaccine in one IM dose.
