Immunocontraception is a birth control method that uses the body's immune response to prevent pregnancy. The Humane Society of the United States continues to lead development of this emerging technology, which offers a humane means of controlling animal populations in situations where it is necessary and appropriate to do so. We have actively forged partnerships with public agencies, communities, parks, zoos, and other entities to test immunocontraceptive vaccines and begin to control wildlife populations.
We have several active deer immunocontraception field sites, including locations in New York, Maryland, and Ohio. In South Africa, we are conducting a series of immunocontraception field tests on elephants. Closer to home, The HSUS is working with biologists and officials of the U.S. National Park Service and Bureau of Land Management to use immunocontraception to control the size of wild horse herds. And, by making immunocontraception technology available to zoos, we are helping to alleviate the suffering that results from the excessive breeding of wildlife in captivity.
Finally, The HSUS is funding non-invasive research to develop long-acting immunocontraceptives and immunosterilants for companion animals. It is our goal to find a safe, one-shot vaccine that can made be available at a low cost to animal shelters, animal control officers, and others who are working to end cat and dog overpopulation.
