Breast nodules and thyroid nodules are generally eligible for the third dose, and the booster shot has no effect on the condition and will not cause worsening of the nodules.
Currently, there are no breast nodules or thyroid nodules among the contraindications for the XKV vaccine, and there is no clinical evidence that the vaccine has adverse effects on breast nodules or thyroid nodules.
Since the booster shot is a booster for the first two doses, it is usually possible to receive the third dose six months later if there are no obvious abnormalities after the first two doses.
After receiving the new crown vaccine, the patient should be closely observed in the observation room for thirty minutes. If there is any redness, swelling and itching at the vaccination site, dizziness and headache, or an increase in body temperature, the patient should consult a doctor for examination in a timely manner.
