Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All subjects indicated to kidney transplantation were considered for inclusion to the trial prior to transplantation. If the patient met inclusion criteria and signed informed consent randomization occurred. Hidden numbered envelops containing the treatment arm were used. Thus the treatment arm was consealed to the researcher until the patient had been included to the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Summary
Brief summary
The aim of the study is to compare the efficacy, safety and cost of preemptive therapy with vaganciclovir (based on quantitative PCR monitoring) versus universal 3-month prophylaxis with valacyclovir (control group, current standard in our transplant centre).
