Creatinine level is not a criterion for determining whether or not to administer the New Crown Vaccine. Creatinine level alone is not a criterion for determining whether the vaccine can be given. If the patient’s creatinine is elevated due to acute kidney injury, no matter how much the creatinine exceeds the normal level before the acute kidney injury is controlled, it is not recommended to inject the vaccine. If the elevated creatinine is caused by chronic renal insufficiency, if the condition is stabilized and there is no severe hypertension and other contraindications to vaccination (allergy to vaccine components, uncontrolled acute illnesses, fever, etc.), the vaccine can be given. In particular, patients with uremia, even with very high creatinine, should be vaccinated with the New Crown vaccine for their own protection due to their reduced immunity. It is recommended to consult the local vaccination center for details.
