Two prizes will be awarded at each congress, one to the best clinical paper and one to the best scientific paper presented at the Annual Congress of the British Transplantation Society.

Call for submissions takes place between mid-September to late November, annually. Winning author/s will be notified by end of December.

Candidates for the prize must be members of the Society prior to abstract submission, and under the age of 40 on the first day of the Annual Congress for which the prize is being considered.

In exceptional circumstances people outside the age range but, still in training, could be considered with a suitable letter of support from their head of department, for example; if they had undergone a period of interruption in their training.

The work must be presented by the candidate and must be original and innovative and have been performed largely or entirely within the United Kingdom. The candidate must have contributed significantly to the work. Submission must be made with the consent of all co-authors who, in doing so, provide confirmation that the rules of the submission have been fulfilled.

Candidates for the prize will be limited to the first author of the submitted paper. In the rare event that the first author cannot present the paper, it must be withdrawn from the competition although the work may be presented by another author in another section of the meeting.

Persons wishing to be considered for the prize must indicate this in their abstract submission.

Past winners of the Medawar Medal cannot apply for the award.

Work submitted to the Medawar session may have been presented at another national or international meeting prior to Congress, but will not be eligible if the work has previously been awarded a national or international Prize.

A piece of work which has previously won the Medawar medal is not eligible for the Roy Calne award.

The judging panel will be chaired by the President of the Society and will usually consist of the President and 8 members of the Society, each of whom will act as rapporteur for one of the papers submitted. The members of the panel will be chosen by the executive  to provide a broad area of expertise. No member of the judging panel may have a direct interest in any of the papers in the competition. If the President has such an interest, he or she will nominate a Member of the Council to act as Chairman. The decision of the panel will be final.

The prize will consist of a medal presented during the meeting/Congress at which the paper is given and £500.
