You can usually get the new crown vaccine after insulin. Insulin injections are given to prevent diabetic patients from experiencing adverse symptoms and to maintain blood glucose in the normal range. Patients with blood sugar within the standard range can be vaccinated. Insulin does not affect the body’s immunity and has no interfering effect on the new crown vaccine. The effect of the new crown vaccine will not be affected, and the new crown vaccine will not directly affect the efficacy of insulin. If the diabetic patient is in the acute stage, blood sugar is now unstable, serious complications, and is now under treatment, then this situation is not recommended to inject the new coronavirus vaccine. You can wait until your condition is stabilized and get vaccinated under the supervision of your doctor.
