Conclusions
Kidney transplant recipients seem to have an antibody response similar
to the general population at the early post-COVID-19 period. However,
similar to the general population there is a tendency toward lower
antibody levels with increasing post-infection duration. Therefore, we
suggest caution for humoral immunity in kidney transplant recipients
following COVID-19; at least following three months post-infection;
follow-up of antibody levels and booster vaccination might be warranted.
