Maternal safety through pertussis vaccination and subsequent maternal-fetal-antibody transfer are well documented, but information on infant protection from pertussis by such antibodies and by subsequent vaccinations is scarce. Since mice are used extensively for maternal-vaccination studies, we adopted that model to narrow those gaps in our understanding of maternal pertussis immunization. Accordingly, we vaccinated female mice with commercial acellular pertussis (aP) vaccine and measured offspring protection against Bordetella pertussis challenge and specific-antibody levels with or without revaccination...

Anti-N-methyl-D-aspartate (Anti-NMDA) receptor encephalitis is an acute autoimmune neurological disorder that can be triggered by virus, H1N1/tetanus/diphtheria/pertussis and polio vaccines or by presence of a tumor. The association between anti-NMDA receptor encephalitis and Japanese encephalitis vaccination was examined and a general protocol of phylogenetic method which details the steps and code and an example of its utility is provided. The approach used here is potentially useful for analyzing the relationship between vaccines and diseases...

Mucosal immunity is often required for protection against respiratory pathogens but the underlying cellular and molecular mechanisms of induction remain poorly understood. Here, systems vaccinology was used to identify immune signatures after pulmonary or subcutaneous immunization of mice with pertussis outer membrane vesicles. Pulmonary immunization led to improved protection, exclusively induced mucosal immunoglobulin A (IgA) and T helper type 17 (Th17) responses, and in addition evoked elevated systemic immunoglobulin G (IgG) antibody levels, IgG-producing plasma cells, memory B cells, and Th17 cells...

The incidence of whooping cough in the US has been rising slowly since the 1970s, but the pace of this has accelerated sharply since acellular pertussis vaccines replaced the earlier whole cell vaccines in the late 1990s. A similar trend occurred in many other countries, including the UK, Canada, Australia, Ireland, and Spain, following the switch to acellular vaccines. The key question is why. Two leading theories (short duration of protective immunologic persistence and evolutionary shifts in the pathogen to evade the vaccine) explain some but not all of these shifts, suggesting that other factors may also be important...

BACKGROUND: During a large measles outbreak in the Netherlands in 2013-2014, infants aged 6-14months living in municipalities with low (<90%) measles-mumps-rubella (MMR) coverage were individually invited for an early MMR using the national electronic immunization register, Præventis. We estimated uptake of early MMR prior to and during the 2013-2014 outbreak and assessed determinants for early MMR vaccination. METHODS: We obtained vaccination records from Præventis, and defined early MMR as vaccination before 415days (13months) of age...

PURPOSE OF REVIEW: Maternal vaccination is a well-tolerated and effective way to protect mothers, their developing fetuses, and their young infants from infectious diseases. Although influenza vaccine and diphtheria, tetanus, and acellular pertussis (Tdap) vaccine are recommended for all pregnant women, uptake rates in the United States remain low. This review will focus on the rationale, scientific evidence, and perceptions of vaccination during pregnancy. RECENT FINDINGS: Recent studies show that administration of influenza and Tdap vaccines during pregnancy is well tolerated and provides protection to the pregnant woman, her fetus, and young infant...

There have been a number of spontaneous reports of sudden unexpected death soon after the administration of Infanrix hexa (combined diphtheria, tetanus, acellular pertussis, hepatitis B, inactivated poliomyelitis and Haemophilus influenza type B vaccine). The manufacturer, GlaxoSmithKline (GSK), submits confidential periodic safety update reports (PSURs) on Infanrix hexa to the European Medicines Agency (EMA). The latest is the PSUR 19. Each PSUR contains an analysis of observed/expected sudden deaths, which shows that the number of observed deaths soon after immunisation is lower than that expected by chance...

BACKGROUND: We sought to examine the relationship between child specific health aid (CHA) and burden of disease. Based on existing evidence, we hypothesized that foreign aid for child health would not be proportional to burden of disease. METHODS: In order to examine CHA and burden of disease, we obtained estimates of these parameters from established sources. Estimates of disability adjusted life years (DALYs) in children (0-5 years) were obtained from the World Health Organization for 2000 and 2012...

INTRODUCTION: In the European Union three different health systems could be defined according to service delivery, financing, and economic policies: Beveridge, Bismarck and Mixed system. Although health systems are hardly to compare, various organizations are developing methods assessing performance. In the present work the performance of the three systems were evaluated using European Community Health Indicators according to Organization for Economic Cooperation and Development. METHODS: The study has been conducted among the 28 states of the European Union using the following indicators: Standardized death rate for diseases of the circulatory system, standardized death rate of malignant neoplasms, road traffic accidents with injury, life expectancy at birth, incidence of Human Immunodeficiency Virus (HIV), infant deaths, pure alcohol consumption, infants vaccinated against Diphtheria Tetanus Pertussis (DTP), public and total expenditure on health over the period 2001-2010...

Pertussis or whooping cough caused by the obligate human pathogen Bordetella pertussis is undergoing a world-wide resurgence. Majority of studies with this pathogen are conducted with laboratory-adapted strains which may not be representative of the species as a whole. Biofilm formation by B. pertussis plays an important role in its pathogenesis. We conducted a side-by side comparison of the biofilm forming ability of the prototype laboratory strains with currently circulating isolates from two countries with different vaccination programs...

REVIEW
Nicole Guiso
Adenylate cyclase-hemolysin toxin is secreted and produced by three classical species of the genus Bordetella: Bordetella pertussis, B. parapertussis and B. bronchiseptica. This toxin has several properties such as: (i) adenylate cyclase activity, enhanced after interaction with the eukaryotic protein, calmodulin; (ii) a pore-forming activity; (iii) an invasive activity. It plays an important role in the pathogenesis of these Bordetella species responsible for whooping cough in humans or persistent respiratory infections in mammals, by modulating host immune responses...

BACKGROUND: The Nigerian National Programme on Immunization aims at increasing the immunization coverage of children under 1 year of age. However, there is still a gap between the national immunization targets and the immunization coverage rates, and data are rarely disaggregated according to socioeconomic status. As a result, there is a dearth of information about the coverage of subgroups, especially at the local level. This study determined the socioeconomic differentials in immunization coverage for children under 5 years and under 1 year in Enugu urban, Southeast Nigeria...

Background Vaccine preventable diseases are making a comeback in the US. However, research is lacking on illness representations of vaccine preventable diseases and their application in improving childhood immunization. Objective We utilized the common sense model of self-regulation to examine illness representations of pertussis and their associations with child's receipt of any vaccine, up-to-date vaccination status, and mothers' intentions to follow the recommended vaccination schedule in the future. Methods We developed vaccine worry and vaccine hassles scales to assess mothers' worries and hassles for child vaccination, and used an open ended question to assess mother's illness representations of pertussis...

BACKGROUND: Pertussis is a vaccine preventable respiratory disease that may cause death mainly in infants. The schedules for primary pertussis vaccination are set in each country by the local health authorities. Several different schedules meet World Health Organization recommendations, 2-4-6mo, 6-10-14wk, 2-3-4mo, and 3-4-5mo being the most commonly used worldwide. In this work, we analyze the benefits of changing the vaccination schedule to control the disease. METHOD: We used an age-structured deterministic mathematical model for pertussis transmission to compute the incidences for the four above-mentioned schedules...
