Sequential or co-administration of vaccines has potential to alter the immune response to any of the antigens. Existing literature suggests that prior immunisation of tetanus/diphtheria-containing vaccines can either enhance or suppress immune response to conjugate pneumococcal or meningococcal vaccines. We examined this interaction among adult Australian travellers before attending the Hajj pilgrimage 2014. We also investigated tolerability of these vaccines separately and concomitantly. We randomly assigned each participant to one of three vaccination schedules...

Despite long-standing vaccination programs, substantial increases in reported cases of pertussis have been described in several countries during the last 5years. Cases among very young infants who are at greatest risk of pertussis-related hospitalizations and mortality are the most alarming. Multiple hypotheses including but not limited to the availability of more sensitive diagnostic tests, greater awareness, and waning vaccine-induced immunity over time have been posited for the current challenges with pertussis...

OBJECTIVES: To evaluate the vaccine coverage of psoriasis patients prior to initiating or changing immunosuppressant therapy, and to verify that the prescribed vaccines have been administered. PATIENTS AND METHODS: We conducted a bi-centre, observational, cross-sectional study over 9 months. Psoriasis patients in whom immunosuppressant therapy (comprising cyclosporine, methotrexate, etanercept, infliximab, adalimumab or ustekinumab) was indicated were included. Medical history, previous treatments, vaccination status, viral serology results (for hepatitis B, measles, and chickenpox), and reasons for non-vaccination were assessed via questionnaire...

INTRODUCTION: The re-emergence of pertussis and the severity of its complications in infants younger than 3 months, were determining factors for starting a vaccination program for pregnant women in the third trimester of gestation in Catalonia in February 2014. This was the first autonomous community to introduce it in Spain. The aim of the study was to estimate the coverage of the program in its first year of implementation. METHODS: A retrospective analysis was performed on the data from the Primary Care Centre computerised medical records of pregnant women attending Sexual and Reproductive Health Care centres of the Metropolitan Nord area of the province of Barcelona, part of the Catalan Institute of Health...

Since the global Expanded Program on Immunization (EPI) was launched in 1974, vaccination against six diseases (tuberculosis, polio, diphtheria, tetanus, pertussis, and measles) has prevented millions of deaths and disabilities (1). Significant advances have been made in the development and introduction of vaccines, and licensed vaccines are now available to prevent 25 diseases (2,3). Historically, new vaccines only became available in low-income and middle-income countries decades after being introduced in high-income countries...

Whooping cough (pertussis) is a highly contagious respiratory infection caused by Bordetella pertussis. Although availability of effective pertussis vaccines seems to decrease the incidence of the disease, B. pertussis circulation in population has not been eliminated. Thus, finding new protein candidates with high immune protective capacities is necessary to enhance the efficacy of current acellular pertussis (Pa) vaccines. In this study, iron superoxide dismutase (FeSOD) gene (sodB) was cloned, expressed in Escherichia coli and recombinant FeSOD protein was purified...

ACT is an essential virulence factor of Bordetella pertussis and antibodies to ACT protect against B. pertussis infection in mice. The toxin is, therefore, a strong candidate antigen for addition to future acellular pertussis vaccines. In order to characterize the functionality of the immunologic response to ACT after infection, we have developed an assay for testing the ability of serum samples from subjects infected with B. pertussis to neutralize ACT-induced cytotoxicity in J774 macrophage cells. Baboons develop neutralizing anti-ACT antibodies following infection with B...

OBJECTIVES: In Lao People's Democratic Republic (PDR) the high burden of vaccine preventable diseases is thought to be mainly due to low vaccine coverage. Here, we investigated the seroprotective response against diphtheria-tetanus-whole cell pertussis-hepatitis B-Haemophilus influenzae type b (DTPw-HepB-Hib) vaccine in children. METHODS: Serum was collected from 1131 children aged 9 to 50 months and their mothers in a cross-sectional study between December 2013 and July 2014...

BACKGROUND: Highest rates of pertussis occur in infants <3 months old, too young to be fully vaccinated. The 2012 national outbreak provided a valuable opportunity to study sources of infection for these infants at highest risk of severe complications and death. METHODS: Households of infants <3 months old with laboratory-confirmed pertussis between 08/2012 and 10/2013 were invited to complete a questionnaire with information on household members' demographics, relationship with the infant, chronology of cough onset where relevant, and vaccination history...

BACKGROUND: World Health Organization recently reviewed the possible nonspecific effects of diphtheria-tetanus-pertussis (DTP) vaccine. The results were considered inconsistent though most studies suggested deleterious effects. We examined whether inconsistencies in results reflected differences in effect of DTP or differences in the methodology used in different studies. METHODS: If children remain unvaccinated because they are frail or if children (including dead ones) with no information on vaccination status are classified as "unvaccinated," the mortality rate becomes unnaturally high among "unvaccinated" controls...

In Belgium, pertussis vaccination is recommended for all pregnant women in every pregnancy. Adults in close contact with young infants are equally advised to receive a pertussis containing booster dose. Maternal influenza vaccination is likewise recommended in Belgium in the second or third trimester of pregnancy, within the influenza season. A quantitative multicenter survey study has been performed between October 2014 and May 2015 in both postpartum women (N=823, response rate=89.2%) and health care workers (HCWs) (N=261) to assess the coverage of both vaccines during pregnancy along with the coverage of the pertussis cocoon strategy, and to evaluate the knowledge and recommending attitude of HCWs towards the maternal vaccination strategies and the cocoon strategy among surveyed women and HCWs...

BACKGROUND: Diphtheria-tetanus-pertussis (DTP) may be associated with increased female mortality; the effect of co-administration with BCG is not known. METHODS: Between 1989 and 1997, we examined female and male mortality rates in rural Senegal where 7824 infants received the first dose of DTP and inactivated polio vaccine (DTP-IPV) with BCG. Subsequent doses of DTP-IPV were administered alone. We analysed mortality according to sex and number of doses of DTP-IPV vaccine...

Infants born to human immunodeficiency virus (HIV) infected women are HIV-exposed but the majority remains uninfected [i.e., HIV-exposed uninfected (HEU)]. HEU infants suffer greater morbidity and mortality from infections compared to HIV-unexposed (HU) peers. The reason(s) for these worse outcomes are uncertain, but could be related to an altered immune system state. This review comprehensively summarizes the current literature investigating the adaptive and innate immune system of HEU infants. HEU infants have altered cell-mediated immunity, including impaired T-cell maturation with documented hypo- as well as hyper-responsiveness to T-cell activation...

CONTEXT: Universal immunization against Bordetella pertussis has partially controlled the burden of the disease and its transmission. However, according to recent data, the epidemiology of this vaccine-preventable disease has changed. Now, younger infants, adolescents, and adults are at greater risk of infection. This article has studied the interaction between the various factors involved in the changing epidemiology of pertussis and the major obstacles faced by the current strategies in its prevention...
