Seroprevalence of Bordetella pertussis antibodies in adults in Hungary: results of an epidemiological cross-sectional study

85.2% of the subjects were seronegative and therefore susceptible to pertussis infection. Approximately 1% was suspicious of current/recent pertussis infection, potentially transmissible to susceptible young infants. Vaccination of adults is a key way to indirectly protect infants.
