Things have gone wrong, of course. The 2006 Theralizumab clinical trial for autoimmune diseases left all six volunteers who were given the drug with severe swelling, disfigurement and life-threatening organ failure. So, lots for gen Z – already a nervous generation – to worry about. But by not volunteering, they also risk missing out on new treatments that won’t find approval as trials stall. And they should consider that if medicines aren’t tested on young people, researchers could miss discovering side-effects that only occur in the young. Someone needs to have a word. And that someone is me, as I volunteered for more than my fair share of medical trials back when I was the age gen Z is now.
