Bruce Lipton is a well-known cellular biologist who has expressed concerns about the current approach to immunology and vaccines. He believes that the traditional focus on germs and pathogens is not sufficient to explain the complexity of the immune system. Lipton argues that the power of the mind and the environment also play crucial roles in determining our immune health. He suggests that a more holistic approach is needed, one that recognizes the interconnectedness of our thoughts, emotions, and physical wellbeing in maintaining a strong immune system.
