If the diabetic patient’s blood sugar is smoothly controlled as evaluated by the doctor, he/she can receive the New Crown vaccine. Diabetic patients can have their blood glucose level tested in the hospital. If the blood glucose is controlled around 7.0mmol/L in fasting state and 10.0mmol/L in 2h postprandial blood glucose level after medication, this state can be vaccinated with New Crown vaccine. The resistance and immunity of diabetic patients are weaker than normal people, so diabetic patients are prone to virus invasion, leading to infection and fever, especially under the attack of New Coronavirus, once diabetic patients have New Coronavirus infection, the symptoms are usually heavier and also prone to some comorbidities. Therefore, vaccination against neo-coronavirus is a very important preventive measure for diabetic patients. It is recommended that diabetic patients keep their blood sugar under control and actively vaccinate themselves against the New Coronavirus in order to reduce the likelihood that they will become infected with it and protect themselves. Diabetic patients with uncontrolled blood glucose or with certain complications can control their diet and exercise appropriately, and then adjust their blood glucose treatment plan under the guidance of a specialist to keep their blood glucose under control as soon as possible and to ensure that their complications are stable before they can receive the vaccine. Do not be overly nervous during the vaccination period, rest properly, drink more water, strengthen self-monitoring of blood glucose and self-monitoring of some symptoms, and seek medical consultation in time if there is any discomfort, and get good results through treatment. Therefore, diabetic patients should not be overly nervous about the New Crown vaccine. After the doctor’s evaluation and the condition is stable, it is recommended to be vaccinated.
