Whether contact dermatitis can be vaccinated with the New Crown vaccine needs to be analyzed according to the patient’s condition. If the contact dermatitis is not an acute exacerbation and the condition is stabilized, then it is usually possible to vaccinate; if the contact dermatitis is an acute exacerbation, then it is not possible to vaccinate. If the contact dermatitis is diagnosed as a common skin disease and is not in an exacerbation phase, and the disease is effectively controlled, then the contact dermatitis can be vaccinated with the New Crown vaccine. The New Crown vaccine does not cause excessive irritation to the body. If contact dermatitis is in an exacerbation phase, the new crown vaccine should be withheld, as many adverse reactions may occur after the injection, and if the new crown vaccine is administered at this time, it is very likely to aggravate the existing condition, so the new crown vaccine should not be administered in this case. If the patient is diagnosed with contact dermatitis and needs to be vaccinated, it is recommended to go to the hospital in time, consult with the relevant doctor, and be vaccinated under the doctor’s guidance.
