Thailand Administers Contraceptive Vaccine to Wild Elephants to Manage Population
Thailand's wild elephant population grew from 334 in 2015 to nearly 800 in 2025, prompting contraceptive vaccinations to reduce human-elephant conflicts and fatalities.
- On Wednesday, Thailand's Wildlife Conservation Office said it administered a contraceptive vaccine to three female wild elephants in Trat province on Monday using a dart gun without anaesthesia.
- Rising population figures show wild elephants increased from 334 in 2015 to almost 800 last year, with an eight percent yearly birth rate in five provinces of eastern Thailand compared to three percent in other regions.
- Earlier tests showed promising results in northern Chiang Mai where seven captive elephants were vaccinated two years ago; officials plan blood checks every six months and another 15 doses before May.
- The move pits conflict reduction against conservation priorities as officials note almost 200 human fatalities and more than 100 elephant deaths since 2012, while Asian elephants remain endangered under the IUCN.
- Targeting high-birth-rate provinces, the program will use another 15 doses on elephants in other herds before this year's rainy season starts in May in five eastern provinces with about eight percent annual birth rate.
