Volume 11, issue 6, e02634-20, 2020, https://doi.org/10.1128/mBio.02634-20. The third paragraph of the Acknowledgments section should read as follows: "Funding for this study was provided by National Institutes of Allergy and Infectious Diseases grant R01AI137679 and by Colciencias through a doctoral fellowship to A.P.-G. We also acknowledge funding from the USDA NIFA (grant 2005-5110-03271) for the original Norwalk virus human challenge study." That is, a wrong NIH project number was previously provided (1K01AI103544) for the funding that partially supported this study. The correct project number is R01AI137679.
