It also goes against previous results from a few different countries so it is probably an anomaly (not weird given how specific the study was, similar to that study which showed delta is, like, ridiculously more contagious, far more than previously thought, which had an extremely unrepresentative sample) and honestly I don't know why many people here are very preoccupied with finding "owns" like this, especially when it is really not helpful whatsoever with increasing vaccinations.
