The chapter defines the importance of immunity against COVID-19. The chapter describes the immunopathogenesis of COVID-19 and the way the body fights back and shows its immune response against the pathogen. Factors affecting immunity include ageing and obesity. The effect of the age factor has been visible in the suffering due to the coronavirus. The chapter also describes the nutritional factors that could boost immunity and enhance the immune response of the body against COVID-19. The major nutritional elements comprise vitamins and micronutrients, responsible for the biosynthesis of amino acids and strengthening of the defence system of the body. Natural products also play an important role in the enhancement of immunity against the coronavirus. The phytoconstituents present in plants play an active biochemical role in controlling COVID-19 symptoms. Vaccination has also helped in gaining acquired immunity against the COVID-19 pathogen and helped in developing herd immunity as well.

Keywords: COVID-19, Immunity, Immunopathogenesis, Herd Immunity, Micronutrients, Phytoconstituents, Vaccination, Vitamins.
