Carlin Aloe, Martin Kulldorff, Barry R Bloom
Because of increased numbers of recorded pertussis cases in the United States, this study sought to understand the role of nonmedical vaccine exemptions and waning immunity may have had on the resurgence of pertussis in the United States at the community level. We used geospatial scan statistics, SaTScan, version 9.4, to analyze nonmedical vaccine exemptions of children entering kindergarten in 2011 and 2012 and reported pertussis cases in 2012 for children in age groups 5 years and younger and 10 to 14 years...

Nabaneeta Dash, Sanjay Verma
Pertussis and rotavirus vaccines have been the subject of several controversies over the years. In this paper the authors discuss facts and myths behind these controversies and also suggest solutions to overcome some limitations of these vaccines. The whole-cell pertussis vaccine (wPV) came into disrepute due to the associated adverse reactions, resulting in its replacement by acellular pertussis vaccine (aPV) in industrialized nations in 1990s. Although wPV is known to have more side effects; but they are usually minor...

BACKGROUND: Since the publication in 2003 of a model to estimate the disease burden of pertussis, new evidence of the protective effect of incomplete pertussis vaccination against severe pertussis has been reported. We revised the model to provide new estimates of regional and global pertussis cases and deaths for children younger than 5 years. METHODS: We developed a revised model with data from 2014 to estimate pertussis cases and deaths. Pertussis cases were defined according to the WHO clinical case definition, as a coughing illness lasting at least 2 weeks with paroxysms of coughing, inspiratory whooping, or post-tussive vomiting...

OBJECTIVES: Assessing timeliness and completeness of vaccine administration is important for evaluating the effectiveness of immunization programs. Few studies have reported timeliness, particularly in Canada. The objective of this study was to examine timeliness of the receipt of vaccination for each routine childhood recommended vaccine by 24 months of age among children in a community-based pregnancy cohort in Calgary, Alberta. METHODS: Survey data from a community-based pregnancy cohort in Alberta were linked to Public Health vaccination records of children (n = 2763)...

AIMS AND OBJECTIVES: To take a systematic approach to reviewing the scientific literature examining the timeliness of vaccination in preterm infants and to identify any factors associated with timeliness. BACKGROUND: Preterm infants are vulnerable to infection and guidance advocates they are vaccinated in accordance with their full term peers. Vaccination is well tolerated and protective immune responses are observed, yet some early enquiries suggest that preterm infants experience unwarranted delays...

Pertussis or whooping cough remains one of the most poorly controlled vaccine-preventable diseases across the world. Universal vaccination has dramatically reduced its incidence but has failed to bring it completely under control. In the last decades, changes in pertussis epidemiology have been noted, likely related to the introduction of acellular pertussis vaccines. Increasing incidence is recorded among adolescents and adults who have become a reservoir for transmission to unimmunized infants, who are at risk of severe disease and death...

Chronic prostatitis (CP) with complex pathogenesis is difficult for treatment. c-kit has been associated with the control of cell proliferation of prostate cells. This study aims to evaluate the role of resveratrol, an activator of Sirt1, in regulating the expression of c-kit in CP and investigate the consequent effects on cell cycle. Rat model of CP was established through subcutaneous injections of diphtheria-pertussis-tetanus vaccine and subsequently treated with resveratrol. Hematoxylin and eosin staining was performed to identify the histopathological changes in prostates...

The challenge of assimilating millions of immigrants in the European region each year presents significant socioeconomic issues. Among them is the threat of vaccine preventable diseases (VPDs) disease transmission within immigrant groups and the broader population given the permeability of nation state borders. A total of 3.8 million people immigrated to the European Union (EU) in 2014, among those were 1.6 million non-EU nationals. While vaccines have markedly reduced the transmission of disease, clusters of under-vaccinated individuals potentiate the rapid transmission of once-eradicated or controlled diseases...

In the Valencian Community (Spain), the programme of maternal pertussis vaccination during pregnancy started in January 2015. The objective of this study was to estimate in this region the vaccine effectiveness (VE) in protecting newborns against laboratory-confirmed pertussis infection. A matched case-control study was undertaken in the period between 1 March 2015 and 29 February 2016. Twenty-two cases and 66 controls (+/- 15 days of age difference) were included in the study. Cases were non-vaccinated infants < 3 months of age at disease onset testing positive for pertussis by real-time PCR...

PURPOSE: Despite the long history of pertussis vaccination and high vaccination coverage in Poland and many other developed countries, pertussis incidence rates have increased substantially, making whooping cough one of the most prevalent vaccine-preventable diseases. Among the factors potentially involved in pertussis resurgence, the adaptation of the Bordetella pertussis population to country-specific vaccine-induced immunity through selection of non-vaccine-type strains still needs detailed studies...

BACKGROUND: Increasing life expectancy results in a larger proportion of older people susceptible to vaccine preventable diseases (VPDs). In the Netherlands, influenza vaccination is routinely offered to people aged 60 years and older. Vaccination against pneumococcal disease, herpes zoster and pertussis is rarely used. These vaccines will be evaluated by the Dutch Health Council and might be routinely offered to older people in the near future. Possible expansion of the program depends partly on the willingness of general practitioners (GPs) to endorse additional vaccinations...

In Japan, the routine immunization program with oral polio vaccine (OPV) has been suspended since September 2012, when a program with 4 doses of inactivated monovalent polio vaccine (IPV) or quadrivalent vaccine against diphtheria, pertussis, and tetanus with IPV (DTaP-IPV) was introduced. The aim of this study was to examine the interchangeability among these 3 types of polio vaccines.We conducted a prospective cohort study at 5 pediatric clinics in Japan. A total of 153 infants were assigned to 1 of the 4 groups by considering the vaccination history of OPV and trivalent vaccine against DTaP...

INTRODUCTION: Adverse events following immunization (AEFI) may follow the use of any vaccine. There is thus a need for documentation of the types and prevalence of AEFIs for each vaccine and early identification of new events or those occurring at rates higher than expected. When one vaccine replaces another, it is important to document the safety of the new vaccine as well as compare to that of the old. In this study, we aimed to document the AEFIs following the use of pentavalent vaccine recently introduced into the National Programme on Immunization and compare with those of diphtheria-tetanus-pertussis (DTwP) vaccine which it replaced...

In 2015, the Belgian National Reference Centre for Bordetella analyzed 4110 respiratory samples by qPCR and 4877 serum samples by serology. Whereas about 50% of respiratory samples were from infants and children below the age of five, serum samples were distributed among all age categories. A total of 394 (9·6%) cases was diagnosed as positive for Bordetella pertussis by qPCR and 844 (17·3%) cases were diagnosed as acute infection by serology (anti-pertussis toxin (PT) IgG > 125 IU/ml). Another 1042 (21·4%) sera had anti-PT IgG between 55 and 125 IU/ml reflecting a vaccination or pertussis infection during the last 1-2 years...

BACKGROUND: Vaccination against pertussis during pregnancy is recommended to protect newborns, yet there is limited information about the effectiveness of maternal tetanus toxoid, reduced diphtheria toxoid, acellular pertussis (Tdap) vaccine before the first infant dose of diphtheria, tetanus and acellular pertussis (DTaP) vaccine and during the first year of life in infants who have received DTaP. METHODS: In a retrospective cohort study of infants born at Kaiser Permanente Northern California from 2010 to 2015, we estimated the effectiveness of maternal pertussis vaccination for protecting newborns against pertussis in the first 2 months of life and in the first year of life accounting for each infant DTaP dose...

INTRODUCTION: Healthcare personnel (HCP) are at risk for pertussis infection exposure or transmitting the disease to patients in their work settings. The Advisory Committee on Immunization Practices recommends tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccination for HCP to minimize these risks. This study assessed Tdap vaccination coverage among U.S. HCP by sociodemographic and occupation-related characteristics. METHODS: The 2012, 2013, and 2014 Internet Panel Surveys were analyzed in 2015 to assess HCP Tdap vaccination...
