A new study reveals the extent to which kidney transplant recipients and individuals with kidney failure who are on dialysis mount immune responses—which include the production of antibodies and the activation of T cells—to COVID-19 vaccination. The findings are published in JASN.
Data are scare on whether kidney transplant recipients and individuals on dialysis receive sufficient protection from COVID-19 vaccines. To investigate, Dominique Bertrand, MD (Rouen University Hospital, in France) and his colleagues examined immune responses after vaccination with the Pfizer-BioNTech COVID-19 mRNA vaccine in 45 kidney transplants recipients and 10 patients undergoing chronic hemodialysis.
After the second vaccine dose, detroit accutane attorney 88.9% of patient on dialysis and only 17.8% of kidney transplant recipients developed antibodies against the virus that causes COVID-19. A specific T-cell response against the virus was evident in 100% of patients on dialysis and 57.8% of kidney transplant recipients. The immune response seemed to be influenced by the immunosuppressive drugs that kidney transplant recipients took, with some drugs having a greater effect than others.
“The vaccine seems efficient in individuals undergoing dialysis, indicating that vaccination should be highly recommended in these patients,” said Dr. Bertrand. “By contrast, the low antibody response observed in kidney transplant recipients is worrying; however, antibodies are not the full spectrum of protection induced by the vaccine. T cell immunity is probably also very important.”
