Are there any foods i can eat to boost my immune system and ward off sars-cov-2?

Foods: I don't know of any foods to ward off any virus, but there are many that will adversely affect your immune system. It's simple logic. Eat a healthy well hounded diet. Avoid overeating, foods high in carbs and fats. There are plenty of sites that will instruct you on a healthy diet.

Please repost: Please repost & clarify what you mean by “boosting,” & why you think your immune system needs it. Cellular or humoral immune system? If humoral, IgM, IgG, IgA or IgE antibodies? If cellular, granulocytes, lymphocytes, plasma cells, monocyte-macrophage system? B-lymphocytes or T-lymphocytes? Helper cells, suppressor cells, natural killer cells? — You see why the term “boosting” is meaningless?
