In 2009, APHIS successfully registered the first immunocontraceptive vaccine for wildlife with the U.S. Environmental Protection Agency (EPA). This vaccine called GonaCon Immunocontraceptive Vaccine (later renamed GonaCon-Deer; EPA Reg. No. 56228-40) was developed by USDA-APHIS Wildlife Services scientists and registered for use in adult female white-tailed deer in urban and suburban areas.
