About this study

Primary objective- To assess the safety of nasal inoculation of healthy volunteers with B. pertussis with antibiotic therapy given to eradicate colonisation at 6 weeks after inoculation or at symptom onset, whichever occurs first Secondary objectives - To measure the rate of natural clearance of carriage of B. pertussis following nasal inoculation * To assess the kinetics of B. pertussis colonisation density following nasal inoculation * To describe the microevolution of B. pertussis and adaptation of the resident microbiome during B. pertussis carriage * To measure B. pertussis-specific antibody and cellular immunological responses in healthy volunteers during colonisation with B. pertussis - To identify biomarkers that correlate with natural clearance of B. pertussis carriage after induced B. pertussis colonisation * To detect transmission of B. pertussis to bedroom contacts of inoculated volunteers during prolonged asymptomatic colonisation
