When we develop vaccines against viruses, those vaccines go through animal trials, safety trials, and then challenge trials before going into widespread real-world trials. Healthy young volunteers are always needed for challenge trials, and they get paid for their work. But that work involves getting a vaccine, then later being deliberately infected with the virus to test their immune responses. That means quarantining and plenty of tests. A testing center in London called FluCamp pays pretty well for your time, so if you are young and healthy and not otherwise employed, you might be tempted to catch a disease for the benefit of medical science ...and a few thousand pounds. Tom Scott visits FluCamp, but he doesn't stay long.
Catch a what on purpose?
