Edited by: Ziwei Zhang, Northeast Agricultural University, ChinaReviewed by: Nicole Ursula Stoffel, ETH Zürich, Switzerland; Sebastian Dolff, University Duisburg-Essen, GermanyThis article was submitted to Nutritional Immunology, a section of the journal Frontiers in ImmunologyKidney transplant recipients (KTRs) have an impaired immune response after vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Iron deficiency (ID) may adversely affect immunity and vaccine efficacy. We aimed to investigate whether ferric carboxymaltose (FCM) treatment improves humoral and cellular responses after SARS-CoV-2 vaccination in iron-deficient KTRs.
