In the statutes of the Nobel Foundation it says: "If none of the works under consideration is found to be of the importance indicated in the first paragraph, the prize money shall be reserved until the following year. If, even then, the prize cannot be awarded, the amount shall be added to the Foundation's restricted funds." During World War I and II, fewer Nobel Prizes were awarded.

38 Medicine Prizes have been given to one Laureate only.
31 Medicine Prizes have been shared by two Laureates.
32 Medicine Prizes have been shared between three Laureates.
Why is that? In the statutes of the Nobel Foundation it says: A prize amount may be equally divided between two works, each of which is considered to merit a prize. If a work that is being rewarded has been produced by two or three persons, the prize shall be awarded to them jointly. In no case may a prize amount be divided between more than three persons.
