Opinions differ on flu vaccinations. Many doctors think that it makes sense to have regular flu shots. I am more of the opinion that it has to be decided on a case-by-case basis. The question is, how stable is the person’s immune system? What is the physical condition of the person? Is there any damage in the blood-brain barrier and in the nerve area? Are there heavy metal contaminations? Can the person cope well with such chemical stresses? I am more in favour of a case-by-case decision. But some people see it differently. It seems to me that it makes more sense to keep the body healthy and strengthen the immune system through a healthy diet, a healthy intestine and immune system, vital substances, minerals, vitamins, fresh fruit and vegetables, exercise in the fresh air.
