Study duration per participant was approximately 28 days for participants 6 months to less than (<) 9 years of age, and 21 days for participants greater than or equal to (>=) 65 years of age, including 1 to 3 visits (1 or 2 vaccination visits) and 1 or 2 telephone calls, depending on study Group.~The aim of study GRC00101 was to obtain serum samples for submission to CBER to aid in the influenza vaccine strain selection process. There were no outcome measures defined in the protocol; however, the number of collected samples was listed as an outcome for disclosure purposes since outcomes were mandatory for study registration.
Primary Objective:~To provide serum samples (collected from participants before vaccination [Blood Sample 1] and after final vaccination [Blood Sample 2]) to Center for Biologics Evaluation and Research (CBER) for further analysis by the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and Food and Drug Administration (FDA) to support formulation recommendations for subsequent influenza vaccines. In addition, serum samples from adult participants may be further analyzed by the Sponsor to assess breadth of immune response induced by the study vaccines.
