I am always asked what can I take to boost my immune system? What shots can boost immunity? I have a master’s degree in immunology and have been working in clinical immunology for 18 years, but I really don’t know of any medicine or food that can boost immunity exactly. But if you ask me what can be done to improve immunity, I will answer “yes”. The 16 words of truth: regular life, light diet, cheerful mood, appropriate exercise.
