Abstract

<p>Recent increases in adolescent and adult rates of pertussis and transmission to newborns and infants at risk for severe infection have become problematic. In 2018, adsorbed diphtheria-purified pertussis-tetanus combined vaccine (DPT vaccine, TRIBIK®) was reissued in Japan due to the need for booster pertussis vaccinations among adolescents and adults. Although DPT vaccinations have been administered to healthcare workers to prevent pertussis in some medical facilities, the current implementation status in pediatric medical facilities is unclear. Therefore, we conducted a questionnaire survey regarding experiences with nosocomial pertussis infection and the status of DPT vaccination for healthcare workers. The subjects were 36 Japanese pediatric medical facilities registered with the Japanese Association of Children's Hospitals and Related Institutions (JACHRI), and we received responses from 35 facilities. The survey results show that 37% (17/35) of facilities had experienced pertussis infection in healthcare workers necessitating antibiotic prophylaxis for numerous other healthcare workers. Only 17% (6/25) of facilities had administered DPT vaccination for healthcare workers. The targets for DPT vaccination depended on the facility. DPT vaccination of pediatric healthcare workers should contribute to the prevention of nosocomial pertussis. There is a very strong need to define targets for vaccination.</p>
