Maria Luz Vilca, Susanna Esposito
Vaccination during pregnancy is increasingly being recognised internationally a useful means of preventing illness in pregnant women and their newborns. It has been used since the 1960s, when it was found that tetanus vaccine was highly effective in preventing neonatal tetanus, but interest has greatly increased over the last few years. As new data become available showing the numerous benefits of maternal immunisation and its potential for improving maternal and neonatal health in relation to a number of infectious conditions, it is being increasingly incorporated into the national vaccination programmes around the world...

When using a case-control study design to examine vaccine effectiveness, both the selection of control subjects and the consideration of potential confounders must be the important issues to ensure accurate results. In this report, we described our experience from a case-control study conducted to evaluate the effectiveness of acellular pertussis vaccine combined with diphtheria-tetanus toxoids (DTaP vaccine). Newly diagnosed pertussis cases and age- and sex-matched friend-controls were enrolled, and the history of DTaP vaccination was compared between groups...

In Japan, the Vaccine Epidemiology Research Group created by the Ministry of Health, Labour and Welfare has played an important role in demonstrating the solid scientific basis for vaccine efficacy and safety since 2002. Members of the group, including epidemiologists, clinicians and microbiologists, have been conducting collaborative studies on vaccines for influenza, pertussis, rotavirus gastroenteritis, polio and pneumonia. So far, the group has achieved several works and contributed to the national vaccination program, including research on the immunogenicity of low doses of influenza vaccine among young children, the immunogenicity and effectiveness of the 2009 influenza pandemic vaccine among various risk groups, the interchangeability of live/inactivated polio vaccines, the health impact of influenza on pregnant women, and the monitoring of influenza vaccine effectiveness using case-control studies with a test-negative design...

INTRODUCTION: Maternal and childhood vaccine decision-making begins prenatally. Amongst pregnant Australian women we aimed to ascertain vaccine information received, maternal immunisation uptake and attitudes and concerns regarding childhood vaccination. We also aimed to determine any correlation between a) intentions and concerns regarding childhood vaccination, (b) concerns about pregnancy vaccination, (c) socioeconomic status (SES) and (d) uptake of influenza and pertussis vaccines during pregnancy and routine vaccines during childhood...

In Italy, in this period, much attention is dedicated to reach adequate vaccination coverage in children and adolescents. In this study, Vaccination Registry was checked in a Local Health Unit in Rome, Italy, to identify children born in 2007 and 2008 who had not completed the vaccination schedule. Coverage for booster doses of measles, mumps, rubella and for diphtheria, tetanus, pertussis and polio vaccines in the 2213 children was around 70%. A reminder letter was send to parents of the 661 incompletely immunized children and, if they did not reply, a phone call was made when the phone number was available...

Infant's immune system cannot control infection or respond to vaccination as efficiently as older individuals, a phenomenon that has been attributed to immunological immaturity. Recently, we challenged this notion and proposed the presence of actively immunosuppressive and physiologically enriched CD71(+) erythroid cells in neonates. Here we utilized Bordetella pertussis, a common neonatal respiratory tract pathogen, as a proof of concept to investigate the role of these cells in adaptive immunity. We observed that CD71(+) cells have distinctive immunosuppressive properties and prevent recruitment of immune cells to the mucosal site of infection...

INTRODUCTION: Subcutaneous (SQ) vaccination has emerged as standard of care in children with severe bleeding disorders to reduce unnecessary factor exposure and avoid provoking an intramuscular bleed, but little is known about comparative immunogenicity to intramuscular (IM) vaccination. AIM: To confirm immunogenicity of Diphtheria Tetanus acellular Pertussis (DTaP) vaccines administered SQ to individuals <6 years old with haemophilia. METHODS: We performed a retrospective and prospective pilot study of tetanus and diphtheria antibody titres among patients evaluated at our Haemophilia Treatment Centre between 2015-2016...

While vaccination injection site adverse reactions are usually mild and transient in nature, several cases of bursitis and other shoulder injuries have been reported in the medical literature. However, these lesions are not included in vaccine label inserts. To identify the characteristics of post-vaccination shoulder injuries and those of patients and involved vaccines, as well as their potential causes, a systematic review of the cases of vaccination-related bursitis and other shoulder injuries reported in the literature and notified to the Spanish Pharmacovigilance System database (FEDRA) have been conducted...

OBJECTIVE(S): While antenatal vaccination is the most effective strategy to reduce newborn pertussis infection and its associated morbidity and mortality, uptake has consistently been reported to be suboptimal. "Cocooning" or vaccination of the close contacts of newborns therefore remains an important strategy for protecting newborns when maternal vaccination has not occurred or with insufficient time for antibody transfer. This study assesses the uptake of pertussis vaccination by parents and close contacts of newborns providing insight into the vulnerability of newborns to pertussis upon discharge from hospital to their primary carers...

BACKGROUND: Adolescent vaccination coverage tends to be suboptimal, leading to resurgent infectious pathologies and vulnerability to various pathogens. The low frequency of medical consultations and missed opportunities for vaccination are often used to explain the low rate of vaccination. The aim of this study was to assess if the vaccination coverage rate is higher in chronically ill adolescents (CIA) who require a close pediatric specialized follow-up versus the rate in healthy adolescents (HA)...

Bordetella pertussis causes whooping cough, a severe and prolonged respiratory disease that results in high morbidity and mortality rates, particularly in developing countries. The number of whooping cough cases is increasing in many countries despite high vaccine coverage. Causes for the re-emergence of the disease include the limited duration of protection conferred by the acellular pertussis vaccines (aP) and pathogenic adaptations that involve antigenic divergence from vaccine strains. Therefore, current vaccines need to be improved...

Whooping cough, or pertussis, is a contagious disease of the respiratory tract that is re-emerging worldwide despite high vaccination coverage. The causative agent of this disease is the Gram-negative Bordetella pertussis. Knowledge on complement evasion strategies of this pathogen is limited. However, this is of great importance for future vaccine development as it has become apparent that a novel pertussis vaccine is needed. Here, we unravel the effect of Virulence associated gene 8 (Vag8) of B. pertussis on the human complement system at the molecular level...
