Characterization of serological responses to pertussis.

Comparative Assessment of the Whole-cell Pertussis Vaccine Potency Using Serological and Intracerebral Mouse Protection Methods

One of the most important QC tests of whole-cell pertussis vaccine (WCPV) is potency test. In this regard, mouse protection test (MPT) is the current potency method, which is associated with severe animal distress and large variability in results. The purpose of this study was to assess Pertussis Serological Potency Test (PSPT) as a serological alternative method to intracerebral challenge in M...

Subcutaneous administration of a fusion protein composed of pertussis toxin and filamentous hemagglutinin from Bordetella pertussis induces mucosal and systemic immune responses

Objective(s): After decades of containment, pertussis disease, caused by Bordetella pertussis seems to be re-emerging and still remains a major cause of reported vaccine-preventable deaths worldwide. The current licensed whole-cell vaccines display reactogenicity while acellular vaccines are expensive and do not induce Th1-type immune responses that are required for optimum protection against t...

Impact of age and vaccination history on long-term serological responses after symptomatic B. pertussis infection, a high dimensional data analysis

Capturing the complexity and waning patterns of co-occurring immunoglobulin (Ig) responses after clinical B. pertussis infection may help understand how the human host gradually loses protection against whooping cough. We applied bi-exponential modelling to characterise and compare B. pertussis specific serological dynamics in a comprehensive database of IgG, IgG subclass and IgA responses to P...
