Response to and outcomes of the Pfizer <scp>BNT162B2</scp> vaccine in hemodialysis patients—A prospective observational study

Abstract

Seropositive patients with low antibody titer might be associated with worse outcome among responders. The ideal antibody titer level among dialysis patient is not known. Also, prior COVID-19 infection is associated with higher response to vaccine with higher antibody titer. All non-responders did not have prior COVID-19 infection. More research is required to further evaluated protective antibody titer.
