Abstract
Studies have shown reductions in the immune response capacity with the aging process (immunosenescence). Lifestyle factors (physical activity and diet) have been investigated as possible adjuvants to improve the effect of vaccines on the immune system in the elderly. The aim of this opinion article is to analyze studies on physical activity and the effect of influenza vaccines in an attempt to suggest that their results can also be found in future studies on physical activity and vaccines against COVID-19. Considering the results of the studies analyzed, it could be suggested that the practice of physical activity improves responses to the influenza vaccine. Thus, it could be assumed that, when transferring these findings to COVID-19, the importance of regular physical activity in the specific elderly population becomes extremely relevant during the COVID-19 pandemic.
