To submit remaining available sera to the Center for Biologics Evaluation and Research (CBER) for further analysis by the Food and Drug Administration (FDA), Center for Disease Control and Prevention (CDC) and the World Health Organization (WHO) to support selection and recommendation of antigen strains for subsequent influenza vaccines.
