- (2) Subjects who are in line with the immunization of this product after medical
history, physical examination and clinical judgment are healthy;
- (3) Participate in this clinical trial after completing 3 doses of immunization = 6
months (calculated based on the date of the last vaccination as 0) in accordance with
the domestically approved inactivated vaccine vaccination program, and can provide
relevant vaccination certificates;
- (4) The subjects are able and willing to comply with the requirements of the clinical
trial protocol, and can complete the study follow-up of about 12 months;

contraceptive measures (such as condoms, intrauterine devices, spermicides) from the
signing of the informed letter to 6 months after the completion of vaccination, and
contraceptive use is not allowed medicine. Female subjects had a negative pregnancy
test and agreed not to breastfeed during the study period and for at least 3 months
after vaccination with the experimental vaccine.
- (6) Underarm body temperature <37.3?.
Exclusion Criteria:

as: allergy, urticaria, severe skin eczema, dyspnea, laryngeal edema, angioedema,
etc.;
- (7) Have received any vaccine within 30 days before vaccination of this research
vaccine or plan to receive any other vaccine other than this research vaccine during
this research;

deficiency, coagulation disorder or platelet disorder), or a history of severe
bleeding, or a history of massive bleeding or ecchymosis after intramuscular injection
or venipuncture;

that affect the function of the immune system, including cancer, congenital or
acquired immunodeficiency (eg: human immunodeficiency virus (HIV) infection),
uncontrolled autoimmune diseases;
- (11) There are serious or uncontrollable diseases of the respiratory system,
cardiovascular diseases, nervous system diseases, blood and lymphatic system diseases,
liver and kidney diseases, metabolic and skeletal diseases that are judged by the
investigator to affect the evaluation of the results of this study;
