Imagine a world where vaccinating wild animals is as simple as flipping a switch. That’s the bold vision behind a groundbreaking invention that could revolutionize how we tackle diseases like bovine TB. But here’s where it gets controversial: could a machine designed to vaccinate shy zoo animals hold the key to ending the contentious culling of badgers in the UK? Let’s dive in.
It all started with a tiger named Cinta, who was too timid to eat in front of her zookeepers at London Zoo. Her keepers faced a dilemma: how to vaccinate her without causing distress? Enter Tony Cholerton, a former motorcycle engineer turned zookeeper, who devised a solution that sounds like something out of a sci-fi movie: Robovacc, a remote-controlled machine that administers vaccinations without human presence. Using a handset from a toy airplane, Cholerton successfully vaccinated Cinta mid-meal, proving the concept’s potential.
But this isn’t just about zoo animals. Cholerton, who retired in 2025 after 30 years at London Zoo, believes his invention could tackle bigger challenges—like the role of badgers in spreading bovine TB to cattle. And this is the part most people miss: while badger culling has been a divisive practice in the UK for over a decade, vaccination offers a humane alternative. However, traditional methods are costly, time-consuming, and stressful for the animals. Cholerton’s fully automated version, Autovacc, could vaccinate up to 20 badgers in minutes, without human intervention.
Here’s how it works: badgers are lured into a Perspex tunnel with food bait. Smart technology ensures each animal is vaccinated only once by spraying nanoparticles on their fur, which activate sensors on return visits. If unvaccinated, the badger is briefly restrained, and a needle injects the vaccine in a split second. Safety features prevent harm, and the animal is released immediately. The machine has already been tested on ring-tailed coatis, proving its effectiveness for tunnel-dwelling species.
Cholerton’s dream? To see Autovacc used by scientists, farmers, and conservationists alike. But here’s the controversial twist: while some argue badger vaccination is the ethical solution, critics like Rosie Wood, chair of the Badger Trust, point out that vaccinating badgers hasn’t shown measurable effects on bovine TB rates in cattle. Wood suggests that if culling isn’t working, vaccination might not either. So, is this a game-changer or a well-intentioned dead end?
What’s undeniable is the invention’s potential beyond badgers. Robovacc has already been used to vaccinate lions and Diana monkeys, with Cholerton noting it works best on carnivores. It could even aid in rehabilitating captive species like Amur leopards by minimizing human contact. But the big question remains: Can technology like Autovacc bridge the gap between conservation and agriculture, or will old debates persist? Let us know your thoughts in the comments—is this the future of wildlife vaccination, or is there more to the story?
