Catherine’s family believed in alternative medicine and she grew up in relatively poor, fringe communities that didn’t have much to do with mainstream science or Britain’s national health system. And when social media became a big part of her life, she started believing in all sorts of wild conspiracy theories.

But when she slowly realised that she was being conned by some of the pseudoscientists and charlatans she had put her trust in, she started to turn a sceptical eye on her online sources.

Catherine now lives a quiet life in southern England with her family, gardening and selling clothes at festivals. She also dedicates her free time to spreading reliable information about medicine and science online. It’s a mission that’s become ever more urgent throughout the global pandemic. Her story gives us insight into why people fall victim to anti-vaccine conspiracy theories - and what can help them to get out.
