Something that  maybe can be used in the future- that depends very much on the Parks Board and their  policy. But at the very least, probably, it can be used on smaller populations of elephant  that are in smaller conservancies where culling and translocation is not an option.\"\u003cbr/\u003eSUPERCAPTION: Professor Henk Bertschinger, Veterinary Science Faculty, University  of Pretoria \u003cbr/\u003eThe vaccine has been tested in horses and white-tailed deer in the U-S without any  noticeable side-effects.\u003cbr/\u003eIts contraceptive effect is reversible in all species except the dog and the rabbit where  permanent sterilisation may result.\u003cbr/\u003eOnce it has been proved to work in elephants, the vaccine will be administered by firing  darts from a helicopter to a selected population of cows.\u003cbr/\u003eKruger National Park, South Africa Oct 10\u003cbr/\u003e1.
