The Claim

Exercise enhances the efficacy of vaccination and cancer immunotherapy by promoting trained immunity in innate immune cells through mitochondrial stress-induced metabolic and epigenetic reprogramming, which improves immune surveillance and response to antigens.

How it works
1 study reviewed
In plain English

Physical activity increases the effectiveness of vaccines and cancer immunotherapies by altering the metabolism and gene regulation of innate immune cells through mitochondrial stress, leading to stronger detection and response to pathogens and tumor cells.

See the scientific wording

Exercise may enhance the efficacy of vaccination and cancer immunotherapy by promoting trained immunity in innate immune cells, potentially through mitochondrial stress-induced metabolic and epigenetic reprogramming that improves immune surveillance and response to antigens.

Why this might work

When a person exercises moderately, their muscles and immune cells work harder, causing their energy factories to produce more stress signals. These signals trigger immune cells to switch how they make energy and change how their genes are read, making them respond more strongly the next time they encounter germs or cancer cells. This effect lasts because the immune cells' instructions are rewritten in a way that gets passed on to new cells, improving the body's ability to fight infections and tumors.

  1. Study: Exercise, mitochondrial stress, and trained immunity: metabolic adaptation of innate immunity

    Regular moderate exercise, like brisk walking or cycling a few times a week, helps your body’s first-line immune defenders learn to respond faster and stronger to germs and cancer cells by stressing their energy factories in a good way. This makes vaccines and cancer treatments work better.
