Correction: Vaccination of Mice Using the West Nile Virus E-Protein in a DNA Prime-Protein Boost Strategy Stimulates Cell-Mediated Immunity and Protects Mice against a Lethal Challenge

The last sentence of the ‘‘WNV DNA Vaccine, Control Plasmid and E-protein’’ section of the Materials and Methods should read: ‘‘For protein booster vaccine formulation the E-protein was adjuvanted with 10 mg Matrix-M1 adjuvant (Novavax AB, Uppsala, Sweden).’’ In addition, the following sentence should be inserted as the last sentence of the ‘‘Vaccination Procedures’’ section of the Materials and Methods: ‘‘Mice were boosted four weeks later either via an IM injection of the same does of WNV-DermaVir nanoparticles or via subcutaneous (s.c.) injection of recombinant E-protein ([28]) formulated with Matrix-M1 (a kind gift from Novavax AB, Uppsala, Sweden).’’
