(1)the subjects used the same vaccine other than the experimental vaccine during the study. (2)any serious adverse reactions that are causally related to vaccination. (3)severe allergic or hypersensitivity reactions after vaccination (including urticaria/skin rash within 30 minutes after vaccination). (4)any confirmed or suspected autoimmune disease or immunodeficiency disease, including human immunodeficiency virus (hiv) infection. (5)acute or new-onset chronic disease after vaccination. (6)other reactions (including severe pain, severe swelling, severe activity limitation, persistent high fever, severe headache, or other systemic or local reactions) are judged by the investigator. (7)acute illness at the time of vaccination (acute illness refers to moderate or severe illness with or without fever). (8)axillary temperature >37.0℃ before vaccination. (9)vaccination of subunit vaccine or inactivated vaccine within 7 days, live attenuated vaccine within 14 days. (10)according to the investigator's judgment, the subject has any other factors that are not suitable for vaccination.
