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

>Has the world been screaming that exercise enhances the vaccination? I think I missed that. Or perhaps I couldn't hear over all the people yelling that healthy people don't die of Covid.

It's been a fact from the start that countries whose populations were in better shape were doing better against covid. The data has been shown many times. A common response to why the US had worse results than other places was "that other place has much less obesity."

Obese people do not have a lot of physical activity.

Yes fitness affects covid prognoses. So does the vaccine. What this study looks at is do these effects interract with each other?

I'll just invent some numbers for illustration. Let's say that the vaccine makes you 10% safer, and exercise also makes you 10% safer. You might expect both to make you 20% safer. But what is that number? It might be 15%. This study indicates that the whole is greater than the sum, so call it 25% in my example.

This is useful to know as we could give advice to patients to either take exercise or rest up after having the vaccine. We don't know the true effect until we look carefully at the numbers.
