What researchers measure

Primary outcomes

  1. Geometric Mean Titer (GMT) of Hemagglutination Inhibition Antibodies Pre-vaccination and 14 Days Post-vaccination

    GMTs and their 95% Confidence interval are presented for each of the 3 antigens in the Fluzone® vaccine 2005-2006 Pediatric formulation. Post-dose 1 (Influenza vaccine Primed group); post-dose 2 (Influenza vaccine Naive group)

    Time frame: Day 14 post-vaccination

Other outcomes

  1. Number of Subjects Who Had Solicited Local and Systemic Reactions Post-vaccination 1

    Solicited local reactions: injection site erythema, injection site swelling, injection site tenderness; Solicited systemic reactions: fever (temperature), irritability, abnormal crying, drowsiness, lost appetite, and vomiting.

    Time frame: 0 to 3 days post-vaccination 1

  2. Number of Subjects Who Had Solicited Local and Systemic Reactions Post-vaccination 2

    Solicited local reactions: injection site erythema, injection site swelling, injection site tenderness; Solicited systemic reactions: fever (temperature), irritability, abnormal crying, drowsiness, lost appetite, and vomiting Note: Influenza vaccine-primed group received only dose 1
