NCT04410471

Brief Summary

This is a prospective study analyzing the development of humoral immune response against SARS-Cov-2 in patients with previous Covid19: the aim is to compare the incidence, titration and evolution of IgG an IgM in a prospective cohort of liver transplant patients surviving to the first wave of Covid19, in comparison to not inmmunossupressed patients.
