Characterization of source plasma from self‐identified vaccinated or convalescent donors during the 2009 H1N1 pandemic

Influenza immune globulin, manufactured from plasma of convalescent or vaccinated donors has been proposed as a potential therapy for severe influenza. In 2009, a program was initiated to collect plasma from donors who self‐identified as having had H1N1 influenza or having received the H1N1 pandemic vaccine. The goal of this study was to determine the efficiency of donor screening by self‐identification without antibody testing, and to evaluate demographic predictors of high‐titer donations.
