Can eczema be prevented?

The baby shows eczema during vaccination period. This problem should be analyzed from three aspects: first, the cause of eczema should be looked at. If the baby is allergic to formula milk, it is not appropriate to take attenuated polio vaccine orally. Inactivated polio vaccine can be used instead. Second, the degree of eczema should be looked at. If eczema symptoms are severe, eczema can be treated first. Finally, the integrity of the skin should be looked at. As long as the skin at the vaccination site is intact and is not allergic to the vaccine, vaccination can be carried out. If the child eczema is more serious, the vaccine should be postponed as much as possible, because there are different types of vaccines, and some vaccines will cause the patient's allergic reaction to worsen after injection.
