Active clinical trials for "Whooping Cough"

This study aims to determine the sero-prevalence of anti-pertussis antibodies among healthcare professionals at hospital centres in Spain.

A multicentre study to evaluate the impact of timing of whooping cough (pertussis) vaccination in pregnancy, with participants randomised to receive whooping cough vaccination at one of three time points in pregnancy.

Pertussis is resurging worldwide. In Africa alone it is estimated that there are 2.1 million cases and 542,000 deaths from pertussis in infants under 1 year with the highest rates of morbidity and mortality in infants <3 months old, before possible prevention via the infant immunization programme1. To protect these most vulnerable infants, the World Health Organisation (WHO) recommends Tdap vaccination as safe in pregnancy and recommends the use of wP vaccines within the EPI. Maternal antibody following aP vaccination can interfere with infant anti-pertussis antibody responses post infant EPI vaccination, which is of concern in high burden settings such as Uganda. There are therefore multiple factors in this population which may influence the effect of pertussis immunization in pregnancy, and which have not been studied, most notably HIV infection and interference with wP vaccines in infants. The immunogenicity of Tdap in HIV-infected pregnant women has not yet been examined. In addition, to date, the effect of maternal vaccination, placental transfer and infant antibody responses in HEU infants have not been studied at all. There are no studies examining the immune response to wP vaccine administered to infants (EPI recommendation) whose mothers received aP in pregnancy.

A prospective, open-label, interventional phase IV study to assess the safety of EupentaTM Inj.{fully liquid pentavalent vaccine, Adsorbed Diphtheria-Tetanus-whole-cell Pertussis-Hepatitis B (rDNA [recombinant-deoxyribonucleic acid])-Haemophilus influenzae type b conjugate vaccine}

This study will aim to recruit at least 70 children who participated in the iMAP2 study whose mothers received a pertussis vaccine in pregnancy as part of the iMAP2 trial and at least 15 children born to mothers who did not receive a pertussis vaccine in pregnancy. Blood samples will be obtained prior to and one month after the routine preschool booster vaccination and vaccine responses compared between children whose mothers received one of two pertussis vaccines or no pertussis vaccine in pregnancy. Children will be vaccinated with the routine booster vaccines by the study team on the same visit as the pre-vaccination bloods are taken.

Implementation of organizational adjustments can enhance involvement of healthcare teams in carrying out flu and pertussis vaccinations, and optimizing access to vaccines for women and their families. Pertussis vaccination of pregnant women is envisaged by the French Health Autority, considering that, given international experiences, vaccination during the second trimester of pregnancy is safe, effective, and would aim to protect babies during the first months of their life. Before considering such a recommendation in France, the acceptability of this strategy by pregnant women and health professionals must be considered.

The purpose of this study is to evaluate safety of GC3111 and to describe immunogenicity of a single dose of GC3111 versus Boostrix® vaccine among healthy adults in 19 to <65 years of age.

Due to waning of infectious as well as vaccine immunity and lack of vaccination boosters, a large number of adolescents and adults are no longer immunized against Bordetella pertussis, the agent of whooping cough and consequently may contract whooping cough. Furthermore, these populations represent a reservoir of the infectious agent from which the dissemination to non-immune infants is possible, causing severe illness, or even death, in this age group. Few studies have been carried out on whooping cough in developing countries (incidence, contaminator's age, etc.) and, specifically, none have assessed the duration of protection induced by the whole cell pertussis (wP) vaccine mainly presently used in these countries. However, data on the duration of vaccine induced protection are essential to determine i) the usefulness of vaccine boosters and ii) the target age group for these boosters. The aims of the present study are: To evaluate the proportion of confirmed pertussis cases in infants presenting whooping cough syndrome (WP1a) To evaluate the proportion of confirmed pertussis cases or healthy carriers among contact cases To determine origin of the infant's contamination (WP1b) To determine the duration of protection induced by the wP vaccines used in contact cases and the child population aged 3 to 15 yo (WP1b and WP2) To bring new scientific evidences documenting the potential need for initiating boosters (WP1b and WP2) To allow a comparison of the results with those obtained using the same methodology for the acellular pertussis vaccine and/or in other contexts. Potential implications for the use of pertussis vaccines in low and moderate income countries. To increase local capabilities by the transfer of materials and expertise that will make the diagnosis of pertussis possible in the centres of reference and strengthen a pertussis monitoring network in the implicated countries. To improve children's health through a better match of the vaccination schedule according to the reality of the situation.

This study aims to determine the burden of pertussis infection among adolescents and adults with prolonged cough in four Asian countries, namely Malaysia, Philippines, Taiwan and Thailand. This study also aims to assess the health economic (HE) impact of pertussis.

To compare the reactogenicity of ADACEL® vaccine given at intervals of 2 to 9 years with the reactogenicity of ADACEL® vaccine given at an interval of 10 or more years following the last previous administration of vaccine containing Diphtheria and Tetanus Toxoids (referred to as TD/Td).
