Reply to comment by brainburger 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

Well yes, because physical activity keeps your body in better health which literally helps things like vaccines work. We've known this forever.

Not quite. We knew that both exercise and vaccines affect covid prognoses separately and likely too that they have overlapping effects. This study makes that point in the introduction.

However it is also the case that exercise increases antibody production after vaccination and that reduces hospitalisation rates. We didn't know that without looking specifically for it in the stats. It was entirely possible for exercise to reduce antibody production, or reduce the effectiveness of the antibodies. We would not necessarily know that, if the overall effect was beneficial.
