Eczema on the face should not be vaccinated. Eczema is closely related to a variety of allergic factors in the clinical setting. There are many allergies that can occur in the clinical setting as a result of preventive injections. After the vaccination, you should not leave the hospital, but wait for about half an hour to see if there is no problem before leaving. If a patient has eczema on his or her face or body, the injection may cause a significant increase in eczema or even cause a serious allergy. Some patients may suffer from severe anaphylaxis or severe respiratory distress. Therefore, in order to prevent the occurrence of serious situations, it is not recommended that patients with eczema have preventive injections, and it is recommended to wait until the eczema has been completely treated before having preventive injections.
