The main IAV strain used in this study was incorrectly named as A/WSN/33. It should have been named A/Puerto Rico/8/34 (typically abbreviated to A/PR8). This correction to the strain name does not change any of the outcomes or findings of the study, as A/PR8 and A/WSN/33 are both highly lab-adapted isolates of influenza A virus subtype H1N1, both with spherical virion morphology, >90% consensus in their HA protein sequences, and >96% consensus in their NP and M1 protein sequences. They also have identical fusion pH values of 5.1 (see ref (1)). The A/PR8 strain was provided by Dr. Jovan Pavlovic at the Institute of Medical Virology, UZH. The other virus strains used in this work remain unchanged.
