For participants aged 3-6: completed the full course of pertussis vaccination (4 doses) according to the immunization schedule, not received pertussis vaccine, Hib vaccine, or combination vaccine containing pertussis/Hib components in the 6-year immunization plan, with an interval of >12 months from the most recent pertussis combination vaccine. For participants aged 18 and above: an interval of >3 years from the most recent pertussis vaccine, Hib vaccine, or combination vaccine containing pertussis/Hib components. 5)*An interval of =14 days from the most recent live attenuated vaccine and =7 days from other subunit or inactivated vaccines. 6)Female participants of childbearing age should not be pregnant or lactating, have a negative pregnancy test before vaccination (menstrual cessation for at least 1 year or surgical sterilization exempts from pregnancy test), and have taken effective contraceptive measures in the 2 weeks before the trial selection. Female participants of childbearing age from the trial selection until 180 days after vaccination and male participants aged 18 and above from the trial selection until 30 days after vaccination should have no plans for pregnancy and agree to use effective contraception during the trial. Effective contraceptive measures include oral contraceptives (excluding emergency contraceptives), injectable or implanted contraceptives, slow-release local contraceptives, hormone patches, intrauterine devices, sterilization, abstinence, male condoms, diaphragms, cervical caps, etc. 7)No axillary temperature =38.0? in the past 3 days, and axillary temperature on the day of enrollment <37.3?.
