Subacute thyroiditis is usually not a vaccine during the onset of the disease, which may worsen the disease and may also cause adverse reactions. During the onset of subacute thyroiditis, patients often experience uncomfortable symptoms such as fever and neck pain. Vaccination in this situation may lead to further aggravation of clinical symptoms, which is not conducive to disease recovery. When patients in the acute phase of subacute thyroiditis are under treatment, they need to apply relevant therapeutic drugs, such as antipyretic and analgesic drugs and glucocorticoids. If the vaccine is administered it may lead to a reaction between the drugs used to treat thyroiditis and the drugs used in the vaccine. Therefore, patients with subacute thyroiditis should try to avoid vaccination during the onset of the disease, through active symptomatic treatment, when the condition is gradually stabilized, you can consult the doctor in detail at what time is suitable for vaccination.
