Beskrivelse
Inclusion Criteria:
- Participants in the 6-11-year-old, 12-17-year-old, and ≥18-year-old groups from the Phase I clinical trial of the adsorbed acellular pentavalent (five-component) DTP-polio combined vaccine (for individuals aged 6 and older) (Protocol No.: CTP-Tdcp-001) who were included in the protocol-defined analysis set;
- Willingness to provide identification documents;
- Informed consent must be obtained from the trial participant and/or guardian and/or authorized representative, and the informed consent form must be signed;
- The trial participant and/or guardian and/or authorized representative must be able and willing to comply with the requirements of the clinical study protocol and be able to complete the full course of study follow-up.
Exclusion Criteria:
- Received another DTP-type vaccine after completing the CTP-Tdcp-001 study;
- Developed a DTP-related illness since the completion of the CTP-Tdcp-001 study;
- Has a coagulation disorder;
- In the investigator's judgment, the participant has any other factors that make them unsuitable for participation in the clinical trial.
