Effects of Exercise on the Immune System and Vaccination Effectiveness

In recent years, the interaction between exercise and immune function has received much attention in the context of vaccine efficacy research. In particular, the rapid popularization of global vaccines during the COVID-19 epidemic has made factors affecting immune response a key issue in the field of public health. The effects of different types, intensities, and timing of exercise on influenza, COVID-19, and other vaccine reactions are investigated in this study. Exercise is a modifiable lifestyle element. Research has found that acute moderate-intensity exercise before vaccination can enhance antibody production, while long-term regular training can help maintain immune memory. Meanwhile, exercise can indirectly enhance immune system function by improving mental health, reducing the negative effects of chronic stress. These results indicate that exercise affects innate and adaptive immunity through mechanisms such as cytokine regulation, improvement of immune cell circulation, and alleviation of chronic inflammation, suggesting that tailored "exercise prescriptions" may be included in vaccination plans to optimize immune protection. This paper emphasizes the importance of exercise in the immune system, provides objective recommendations, and outlines future research directions, providing a scientific basis for enhancing vaccine efficacy and immune function through exercise.
