In compliance with Thailand's conditional approval requirements, this prospective, observational study is designed to actively monitor the safety of VacPertagen vaccine. Healthcare professionals (HCPs) prescribing or administering the vaccine are recruited from hospitals and clinics across central, eastern, southern and northern Thailand. Adverse events following immunization (AEFIs) are reported through standardized questionnaires and modified WHO AEFI forms, enabling systematic evaluation of the vaccine's safety profile in a broader and more heterogeneous population than that assessed in pre-licensure trials.
Primary objective: To describe the post-licensure safety profile of VacPertagen in Thailand.
Secondary objective: To identify any unexpected safety signals following vaccination with VacPertagen.
