Biofilm forming potential and antimicrobial susceptibility of newly emerged Western Australian Bordetella pertussis clinical isolates

Isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomic analysis revealed significant differences in protein expression in B. pertussis biofilms

Whither pertussis?

This article discusses the rising prevalence of pertussis disease in countries which have switched to acellular vaccines.

Predictors of Disease Severity in Children Hospitalized for Pertussis during an Epidemic

This study aimed to determine factors associated with severe pertussis in hospitalized children during an epidemic using a novel pertussis severity scoring...

Antibody and cell-mediated immunity to pertussis 4 years after monovalent acellular pertussis vaccine at birth

In the longest reported follow-up of infants who received aP vaccine at birth, we found a trend to lower PT IgG antibodies post booster compared with receipt...

Duration of protection after first dose of acellular pertussis vaccine in infants

Without a booster dose, the effectiveness of 3 doses waned more rapidly from 2 to 4 years of age than previously documented for children >6 years of age who...

Re-think on strategies to prevent whooping cough in newborns

Governments should rethink strategies to prevent whooping cough in newborn infants, including booster vaccination of close contacts of the baby.

Vaccination

Vaccination is the injection of an inactivated bacteria or virus into the body. This simulated infection allows an individual's immune system to develop an adaptive immunity for protection against that type of illness. When a sufficiently large percentage of a population has been vaccinated, this results in herd immunity.

Infant Whole-Cell Versus Acellular Pertussis Vaccination in 1997 to 1999 and Risk of Childhood Hospitalization for Food-Induced Anaphylaxis: Linked Administrative Databases Cohort Study

Evidence suggests that children who had received an initial priming dose of whole-cell pertussis (wP) vaccine, rather than acellular pertussis (aP) vaccine, had a lower risk of developing IgE-mediated food allergy, the most common cause of anaphylaxis-related hospital presentations of childhood.

Association between pertussis vaccination in infancy and childhood asthma: A population-based record linkage cohort study

Asthma is among the commonest noncommunicable diseases of childhood and often occurs with other atopic comorbidities. A previous case-control study found evidence that compared to children who received acellular pertussis (aP) vaccines in early infancy, children who received one or more doses of whole-cell pertussis (wP) vaccine had lower risk of developing IgE-mediated food allergy. We hypothesized that wP vaccination in early infancy might protect against atopic asthma in childhood. 

Immune impacts of infant whole-cell and acellular pertussis vaccination on co-administered vaccines

We compared the effect of a heterologous wP/aP/aP primary series (hereafter mixed wP/aP) versus a homologous aP/aP/aP primary schedule (hereafter aP-only) on antibody responses to co-administered vaccine antigens in infants and toddlers.
