- Chronic use of systemic steroids (>10 mg/day prednisone equivalent for periods exceeding 14 days), cytotoxic or other immunosuppressive drugs within the past 6 weeks.
Any abnormality or chronic disease which in the opinion of the investigator might be detrimental to the safety of the participant and interfere with the assessment of the study objectives.
① Respiratory diseases: Asthma, Chronic Obstructive Lung Disease (COPD), active or latent tuberculosis which require medication, etc.
② Serious cardiovascular diseases: Congestive heart failure, coronary artery disease, myocardial infarction, uncontrolled hypertension, myocarditis, pericarditis, etc.
③ Neurologic diseases: Epilepsy, seizure within 3 years, migraine, stroke, encephalopathy, Guillain-Barre Syndrome, encephalomyelitis, acute transverse myelitis, etc.

- Individual with past history of thrombocytopenia and/or thrombosis, myocarditis or pericarditis or any other significant cardiac condition.
- Individual with a known bleeding diathesis, or any condition that may be associated with a prolonged bleeding time resulting in contraindication for IM injections/blood extractions (Those who receive low dose aspirin (less than 100mg/day) are not excluded).
