Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single center, open-label phase1b clinical trial. The study will evaluate the safety and immunogenicity of an experimental recombinant staphylococcus aureus vaccine with different immunization schedules in healthy adults aged 18-70 years, including day 0-3-7, day 0/0-3-7, day 0/0-7 and day 0/0-7-14.

* Coagulation disorders (coagulation factor deficiency, coagulopathy or platelet disorder) diagnosed by doctors, or obvious bruises or blood coagulation noticed.
* History of allergic disease likely to be exacerbated by any component of the vaccine, including allergy, urticaria, respiratory difficulty, angioneurotic edema or abdominal pain. Any autoimmune disease or immunodeficient state, parents, brother and sister with autoimmune disease or immunodeficient disease.
* Taking immunoglobulins and/or any blood products within the last 12 months.
* Asplenia, functional asplenia or asplenia caused by any situation or splenectomy.
* Any acute disease or acute attack of chronic disease in last 7 days.
* History of thyroidectomy or thyroid disease requiring treatment in the last 12 months.
* Immunosuppressor, cytotoxic therapy, inhaled corticosteroid (excluding corticosteroids spray treatment of allergic rhinitis, acute and nonconcurrent corticosteroids treatment)
* Participation in another research study involving receipt of an investigational product in the last 30 days.
* Woman who is breast-feeding.
* Prior administration of attenuated vaccine in last 28 days.
* Prior administration of subunit vaccine, inactivated vaccine or allergic therapy in last 14 days.
* Current anti-tuberculosis therapy or HIV infected individuals
* Any other conditions may compromise the safety or availability of participants in the judgment of the investigator.
