Reply to comment by Seattleshouldhaverun in Regular physical activity may boost effectiveness of COVID-19 jab. Risk of hospital admission among fully vaccinated healthcare workers was reduced by 60% in the group who engaged in low levels of physical activity, and by 72% and 86% in the medium and high physical activity groups, respectively by Wagamaga
It's hard to parse from just the abstract if they did their analysis correctly, but they did say they were looking for an "effect modifier" which I would interpret as an interaction effect. That is to say, vaccination is designed to reduce your hospitalization risk, and physical activity may also do this even in unvaccinated people, but the effect of having both on your side is more than just adding up the two factors individually.
Again, I can't tell from what I'm able to access if they actually showed that, but it sounds like that is what they are claiming.

They used the unvaccinated in each exercise group as the reference. If you open Table 2 you'll see there is no p-value for the unvaccinated in each group. So they did not compare someone unvaccinated who has a high level of exercise to someone vaccinated with a low level of exercise, for instance. (At least from what I could quickly see)
