Eligibility Criteria

• Age: 18 Years - 65 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects are able to understand and are willing to sign the informed consent form (ICF).
• Subjects (male or female) must be ≥18 to ≤65years of age inclusive.
• Healthy subjects according to the results of medical history, physical examination, vital signs, ECG, and clinical laboratory examination. The Investigator considers that the subjects are in good health with no clinically significant heart, liver, kidney, digestive tract, nervous system, respiratory system, mental disorders, and metabolic disorders.
• Subjects with a body mass index (BMI) of 20-32kg/m\^2, inclusive.
• (1)If a subject is a female of childbearing potential - she should agree to use one of the accepted contraceptive regimens from at least 30 days before screening, during the study, and for at least 3 months after administration of the study treatment.1)An acceptable method of contraception includes one of the following:
• Abstinence from heterosexual intercourse;
• Hormonal contraceptives (birth control pills, injectable/implant/insertable hormonal birth control products, transdermal patch);
• Intrauterine device (with or without hormones). 2)OR she should agree to use a double-barrier method (e.g., condom and spermicide) during the study and for at least 3 months after administration of the study treatment.
• (2)If a subject is a female of non-childbearing potential - she should be surgically sterile (i.e., has undergone complete hysterectomy, bilateral oophorectomy, or tubal ligation/occlusion) or in a menopausal state (at least 1 year without menses), as confirmed by Follicle stimulating hormone (FSH) levels (≥40 mIU/mL).
• A male study subject that engages in sexual activity that has the risk of pregnancy must agree to use a double-barrier method (e.g., condom and spermicide) and agree to not donate sperm during the study and for at least 90 days after administration of the study treatment.
• Subjects understand the risks of the study, can comply with the study protocol, and complete the study.

You may not qualify if:

• History of cardiovascular, respiratory, kidney, liver, metabolic, endocrine, gastrointestinal, blood, neurological, skin, psychiatric, cancer, or other major serious diseases that in the judgment of the Investigator might put the subject at risk on this study.
• History of tuberculosis (active or latent) irrespective of treatment status or infection within the past 4 weeks or history of recurrent infections.
• History of or current active autoimmune disease or immunodeficiency disease.
• Subjects who have a history of clinically significant drug allergy or atopic allergic disease or known allergic reaction or hypersensitivity to the study treatment or its excipients according to the judgment of the Investigator.
• Subjects who have a history of drug abuse in the 12 months before screening or who have a positive urine drug tests at the time of screening.
• Subjects who have taken biologic agents within 3 months or 5 times the half-life (whichever is longer) before screening, or who have taken drugs that may affect immune function within 6 months or 5 times the half-life (whichever is longer) before screening, or over-the-counter (OTC) medications (including herbal medicines such as St John's Wort, homoeopathic preparations, vitamins, and minerals) within 7 days prior to IMP administration.
• Subjects who have received treatment with an investigational drug within 30 days or 5 times the half-life (whichever is longer) prior to screening or 90 days for biologic compounds prior to screening.
• Blood donation (excluding plasma donation) of approximately 500 mL within 56days before screening or plasma donation within 7 days before screening.
• Those whose daily consumption of alcohol at the time of screening or at any time within the prior 6 months is more than 2 standard drinks, where 1 standard drink = 355 mL or 12 oz (1can) of regular-strength (5%) beer; 150 mL or 5 oz wine; 45 mL or 1.5 oz liquor/spirits (40%) or who are positive for alcohol tests during the screening period.
• Female subjects who are breastfeeding or pregnant or who have positive serum pregnancy test during the screening period and on admission.
• Subjects who have difficulty in venous blood collection or who exhibits risk of fainting after blood collections or with the site of needles.
• Human immunodeficiency virus (HIV) antibody, hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody test results are positive during the screening period.
• Any acute or chronic condition that, in the opinion of the Investigator, would limit the subject's ability to complete and/or participate in this clinical study.
• Subjects who have participated in any vaccine clinical study as subjects within 3 months before enrollment or plan to receive live vaccines during the study period, and subjects who have received inactivated vaccines 28 days prior to the IMP administration or plan to receive inactivated vaccines within 2 months after the end of the study.
