Susceptibility and Factors of Pertussis Vaccination Adherence in Korean Health Care Workers

Objective: To examine pertussis susceptibility and identify factors that might influence commitment to pertussis vaccination plan among Korean health care workers. Methods: The susceptibilities were examined using Bordetella pertussis IgG ELISA. The individual and related behaviors and cognition and affect factors were measured. Results: Approximately 20% of subjects were susceptible to pertussis. Only perceived sensitivity and social support system were found to have significant direct effects on commitment to vaccination plan. Conclusions: Vaccination with pertussis among health care workers is certainly needed in Korea. In practice, when developing educational programs, perceived sensitivity and support systems need to be specifically considered.
