Being on Entecavir, patients are allowed to get the New Crown vaccine if their disease is stable, but not if the disease is in a progressive stage. Entecavir is an antiviral drug that is mainly used in the treatment of hepatitis B patients. Whether or not the New Crown vaccine can be administered depends on the progress of the disease. If the patient’s condition is in a progressive stage, the New Crown vaccine is not allowed because acute exacerbations of chronic diseases, or patients with uncontrolled severe chronic diseases are contraindications to the New Crown vaccine. However, if the patient’s condition is stable and he or she is in good physical condition, and if other contraindications to vaccination have been ruled out, the patient can be vaccinated under the supervision of a physician.
