Abstract: Various embodiments provide a method of increasing immunity to a virus in a subject. The method can comprise administering to the subject one or more effective doses of an immune-enhancing natural-based composition; thereby stimulating increased expression one or more of IFN-?, IL-1B, IL-6, IL-10, IL-12p40, IL-12p70, and TNF-?; inhibiting replication of the virus inside a cell of the subject, and preventing entry of virus into the cell. The method of increasing immunity can further comprise increasing immunity to an upper respiratory tract viral infection. The upper respiratory tract viral infection can be COVID-19. According to some aspects of the method of increasing immunity, the effective dose of the immune-enhancing natural-based composition comprises: 30-70 mgs of cyanidin-3-glucosides; 40-80 mgs of andrographolides; 75-125 mgs of ascorbic acid; 400-600 mgs of beta glucans; 300-500 mgs of polysaccharides; and 75-125 mgs of a blend of antioxidants.
