In the Original Investigation titled “Evaluation of the SARS-CoV-2 Antibody Response to the BNT162b2 Vaccine in Patients Undergoing Hemodialysis,”1 published September 2, 2021, there were errors in the Abstract and Figure 1. In the Abstract Results, the second use of the phrase “in convalescent serum from COVID-19 survivors” should have been omitted. In the Figure 1 color key, the colors given for “PCR-positive” and “PCR-negative” should have been reversed. This article has been corrected.1
