Whether or not a hyperthyroid patient can receive the New Crown vaccine depends on the patient’s current stable condition and physical status. If a hyperthyroid patient’s condition is stable after medication control, and the blood tests for thyroid hormones are within the normal range, and if he or she is in good health and does not have any complications or discomfort, he or she can be vaccinated with the new crown vaccine, but before vaccination, he or she should ask the doctor again or consult the professional technicians for vaccination. However, if a hyperthyroid patient is in the stage of more obvious symptoms of hyperthyroidism, such as serious liver function damage, cardiac arrhythmia, active proptosis, and wasting, the immunity of the body is lower at this time, so it is recommended to postpone the vaccination of the new crown vaccine, because the new crown vaccination depends on the normal immune function to produce effective antibodies. In addition, for patients who have just entered the period of hyperthyroidism treatment, it is also not recommended to have the vaccination because hyperthyroidism drugs can cause some adverse reactions to the body in the early stage of taking them, and then the vaccination may aggravate the adverse reactions.
