  • We investigated the in vivo contributions of Fc interactions with their cognate receptors for a collection of neutralizing anti-influenza antibodies. (mssm.edu)
  • Antibodies levels ≥0.01 IU/mL as measured by in vivo toxin neutralization assays are generally considered protective (Borrow, et al. (cdc.gov)
