17 PZP Birth Control Vaccine

Please note that hormonal birth control vaccines are not recommended. These have caused serious side effects and health problems, including the permanent infertility of cows, during field trials. By contrast, as we shall see in this section, the PZP vaccine causes temporary immunity to sperm cells and is, therefore, termed an immunocontraceptive. In addition to reading research papers about PZP, I discussed its use for elephant birth control with Teresa Teleky, Ph.D., who is the Director of Wildlife at Humane Society International. She is well acquainted with the vaccine. I am also in correspondence with Henk Bertschinger, Ph.D. who heads the PZP laboratory responsible for the PZP contraceptive vaccine in South Africa. Their recommendations, along with the testimonies of several scientists and wildlife conservationists, assures me that PZP is clearly the vaccine of first choice for elephant birth control. Here are some of the benefits of PZP: • Contraceptive efficacy of at least 90% • Remote delivery of the vaccine which means that no handling of animals (thereby reducing stress) is required and substantially reduces the costs of treatments • Reversibility of contraceptive effects • No harmful effects in pregnant elephants • The absence of either short or long-term significant health effects • No effects on social behaviors in either short or long-term • Target specificity i.e. the contraceptive agent does not pass through the food chain (See Kirkpatrick and Turner 1996, Kirkpatrick 2010, 2012)
