In France, it has been recommended since 2022 that pregnant women be vaccinated against pertussis from 20 to 36 weeks' gestation. This vaccination schedule is inspired by the Anglo-Saxon model and studies showing the effectiveness of this practice. The aim of this vaccine is to protect the newborn by transferring antibodies from the fetus to the placenta, because Pertussis is a particularly serious disease in newborns.
The resurgence of pertussis is associated with an evolutionary mechanism under the pressure of current acellular vaccines, with a possible impact on vaccine effectiveness and disease expression. Little is known about the mechanisms involved in the clinical variability of pertussis, including its most severe malignant form observed in infants (mortality between 50-80%). The main challenges are: (i) the lack of knowledge about the gene expression of B. pertussis strains currently circulating during human infection, incorporating evolutionary changes and vaccine-induced selective pressure; (ii) the poor understanding of the variability in clinical expression of pertussis, and (iii) the lack of biomarkers to predict disease severity or prognosis in infants. An integrative strategy combining a clinical, microbiological, immunological and 'omic' approach from a prospective cohort of children with pertussis will be used to identify 1. 'in situ' expression profiles of B. pertussis genes and proteins incorporating recent evolutionary changes and 2. a systemic and respiratory immune signature in B. pertussis-infected children according to severity. Results should furthermore serve as a prerequisite for the identification of severity biomarkers and new vaccine antigen candidates taking into account specific immune responses in infants.
The overall objective of the project is to identify the determinants of antibody-mediated immunity in infants born to mothers immunized during pregnancy. Using maternal pertussis immunization as a model, the project will identify key predictors and potential determinants of vaccine responses in pregnant women, of the transfer of maternal antibodies to the newborn and of vaccine responses in infants. A systems biology approach will be used to delineate pre-vaccination and post-vaccination cellular and molecular correlates of the immune response to pertussis immunization in peripheral blood and in breastmilk.
The purpose of this study is to evaluate immunogenicity and safety of different doses of candidate hexavalent vaccine in comparison to co-administration of Pentavalent vaccine and Poliomyelitis Vaccine (Inactivated) in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants and thereby to select the optimal dose of candidate vaccine(Stage 1) and to demonstrate lot-to-lot consistency of three lots of LBVD (Stage 2)
Pertussis (also known as whooping cough) is a highly contagious, vaccine-preventable respiratory tract disease, caused by the bacteria Bordetella pertussis. It can affect people of all ages, however young unimmunised or partially immunised infants are the most vulnerable group with the highest rates of complications and death. Recent surveillance data and an increase in the number of pertussis outbreaks being reported nationally, indicate an increase in the incidence of pertussis disease in South Africa.To date there is no data on the effect of vaccinating HIV-infected pregnant women with pertussis-containing vaccines, although there is no reason to think that vaccinating these women would be harmful for them or their foetus. The knowledge gaps on the immunogenicity, safety and VE of pertussis vaccination of HIV-infected pregnant women should be addressed. Adacel which is a registered and licensed vaccine manufactured by Sanofi Pasteur, will be tested in this study.
A prospective, multi-center, observational clinical trail. Aim to evaluate the real incidence of COPD pertussis and the impact of pertussis on subaute cough.
A prospective, multi-center, observational clinical trail. Aim to evaluate the real incidence of chronic obstructive pulmonary disease (COPD) pertussis and the impact of pertussis on COPD exacerbation.
The purpose of the study is to evaluate immunogenicity and safety of three different doses of candidate hexvalent vaccine in comparison to co-administration of EupentaTM Inj. and Imovax® Polio in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants and thereby to select the optimal dose of candidate vaccine
