The present invention provides a vaccine which is protective against avian polyomavirus infection in a bird which is classified as being a member of the Psittaciformes order which comprises an immunogenic amount of a modified live avian polyomavirus in a pharmaceutically acceptable carrier. Methods are also provided for preventing avian polyomavirus infection in a bird, or in several different species of birds, classified as being a member of the Psittaciformes order, comprising administering a vaccine comprising an immunogenic amount of a modified live avian polyomavirus and a pharmaceutically acceptable carrier. A preferred embodiment provides a modified live avian polyomavirus vaccine for prevention of wild-type infection in a Budgerigar, lovebird or Cockatiel.
Matching (e.g., via correlation or similarity process) entities having attributes, some of which have associated values. The values of the attributes may be adjusted based on number of entities that have values for a particular attribute so that the values decrease as the number increases. The attributes of the entities may be harmonized and provided with default values so that entities being matched have common attributes defined by the union of the attributes of the entities being matched. The attributes of the entities may be expanded and provided with default values so that the entities being matched have attributes that neither had originally. Match values may be normalized to provide a weight value which may be used to predict an attribute value of a new entity based on known attribute values of known entities. The weight values may be tuned such that relatively high weights are amplified and relatively low weights are suppressed.
