I'm pretty young and fairly healthy, so a licensed vaccine was a long way off (and still is) for me personally. The 50% chance of possible protection from Covid-19 was something of a selfish motivator, but more generally it seemed like a good thing to do to try and help society return to some sort of normality (I work in a sector which has been hit quite badly) - of course, there was probably no shortage of volunteers so my space likely would've been filled without my participation. It also seemed like a kinda fun thing to do, though - I find medical sciences pretty interesting and had read through and familiarised myself with the phase 1 & phase 2 trial results for Ad26.COV2.S. I thought it'd be an interesting experience and the risks seemed acceptable to me. The only downsides so far have been the distance I have to travel to get to the clinical research facility and the fact that I don't really like the sight of blood. I've had so many blood tests (in this study and outside) that I'm fine with the process, but I prefer not to watch.
