The immunogenicities and efficacies of a licensed diphtheria, tetanus, acellular pertussis, and inactivated poliovirus vaccine and the same vaccine formulated in a liposome/oil emulsion adjuvant were compared in a mouse model of pertussis respiratory infection. A single dose of the liposome/oil emulsion-adjuvanted vaccine produced significantly higher antibody levels than one dose of the licens...

Pertussis or whooping cough is a highly infectious, vaccine preventable disease. The incidence of the disease  has greatly been reduced since the introduction of the diphtheria, tetanus, pertussis vaccine. Pertussis resurgence has been observed in highly vaccinated populations of Western countries since 1990s. Poor vaccine quality, waning vaccine induced immunity, pathogen adaptation, and enhan...

OBJECTIVE To evaluate the safety of infant immunization with acellular pertussis vaccines in the United States. BACKGROUND The US Food and Drug Administration approved the first acellular pertussis vaccine for use in infants in the United States on July 31, 1996. OUTCOME MEASURES Adverse events in the United States after infant immunization with pertussis-containing vaccines, representing t...

BACKGROUND Unexpected waning of immunity after pertussis vaccination is now well described. In this study we examined whether prior vaccination with whole-cell pertussis vaccine (wP) at any point provided superior protection contrasted with a solely acellular pertussis vaccine (aP) series. We utilized the coincidence of a large outbreak of pertussis with the termination of wP availability, prov...

OBJECTIVE The objective of this study was to determine if children who contracted pertussis infection were more likely to have parents who refused pertussis vaccinations than a similar group of children who did not develop pertussis infection. METHODS We conducted a case-control study of children enrolled in the Kaiser Permanente of Colorado health plan between 1996 and 2007. Each pertussis c...

IMPORTANCE Undervaccination is an increasing trend that potentially places children and their communities at an increased risk for serious infectious diseases. OBJECTIVE To examine the association between undervaccination and pertussis in children 3 to 36 months of age. DESIGN Matched case-control study with conditional logistic regression analysis. SETTING Eight managed care organization...

Background and aim Pertussis risk increases during pregnancy when it can be passed from an infected, non-vaccinated mother to the newborn. The pertussis vaccine, Boostrix (Tdap: tetanus, diphtheria, pertussis), was approved by U.S. Food Drug Administration (FDA) for immunization of pregnant women third trimester. current cross-sectional study aimed assess awareness level towards pertussis. Meth...

We assessed the effectiveness of complete and partial pertussis vaccination in Germany--a country where acellular vaccine is predominantly used--for the prevention of cases of pertussis requiring hospitalization. Vaccine effectiveness was estimated by means of a screening method. Vaccine coverage of children born during the period of June 1996 through December 1998 was assessed by a telephone s...

Bordetella pertussis is the causative agent of pertussis. Here, we report the genome sequence of Bordetella pertussis strain CS, isolated from an infant patient in Beijing and widely used as a vaccine strain for production of an acellular pertussis vaccine in China.

Although tetanus and diphtheria have become rare in developed countries, pertussis is still endemic in some developed countries. These are vaccine-preventable diseases and vaccination for adults is important to prevent the outbreak of disease. Strategies for tetanus, diphtheria, and pertussis vaccines vary from country to country. Each country needs to monitor consistently epidemiology of the d...
