"Boosting Vaccine Effectiveness: The Power of Exercise, Diet, and Mood"

Research suggests that various lifestyle factors, such as mood, sleep, diet, exercise, and social interactions, can affect the efficacy of vaccines, including flu shots and COVID-19 jabs. Positive mood, adequate sleep, a healthy diet, regular exercise, and strong social connections have been associated with better antibody response to vaccines. Factors like age and genetics also play a role in vaccine response. While the exact mechanisms are not fully understood, these lifestyle factors can potentially enhance the immune system's ability to fight diseases and improve vaccine efficacy.
