It could just be that people on the placebo took more risks than the people who didn't which is why it is a statistical outlier.
Why would they take more risks? The whole point of a placebo is that you don't know if it's a placebo or not. So there's no reason to expect a change in behavior in one group versus the other. In fact, the behavior change should be driven in the other direction. If there was some reason to think that you got the vaccine (say, side effects not present with the placebo), then you would be likely to increase your risky behavior and increase your likelihood of infection! In this case, they got an effect in the other direction -- the treated group had less infections.
