Filter by:Phase III, open, mono-center study in 177 infants who received a dose of Hep B vaccine at birth or within 1 month after birth. Infants will receive Sanofi Pasteur's DTaP-IPV-Hep B-PRP-T combined vaccine (study vaccine) at 2, 3, and 4 months of age. All subjects will provide blood samples for immunogenicity assessment at baseline (pre-vaccination) and at 30 days following the third vaccination. Regarding safety, solicited reactions and unsolicited non-serious adverse events (AEs) will be collected up to 7 days and up to 30 days after each vaccination, respectively. Serious adverse events (SAEs) will be collected throughout the study trial (from Visit 1 to Visit 4)
This study aims to assess and confirm the adequate immunogenicity and safety profile of the Sanofi Pasteur's DTaP-Hep B-IPV-PRP-T fully liquid combined hexavalent vaccine administered in HIV-exposed uninfected infants and in HIV-exposed infected infants. The primary objectives of the study are: - To evaluate the immunogenicity of the study vaccine 1 month after the 3-dose primary series in HIV-exposed infected and in HIV-exposed uninfected infants. - To describe the persistence of all antibodies before receipt of the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. - To evaluate the immunogenicity of the study vaccine 1 month after the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. The secondary objectives of the study are: - To describe the safety profile after each and all doses of the study vaccine administered as a 3-dose infant primary series in HIV-exposed infected and in HIV-exposed uninfected infants. - To describe the safety profile of the study vaccine administered as a booster in HIV-exposed infected and in HIV-exposed uninfected infants.
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.
This study has three purposes: To investigate whether the immune response to pertussis is increased when TDaP-IPV is given together with BCG vaccine, compared to when it is given alone. To investigate whether BCG vaccination modulates the immune response to non vaccine target antigens (i.e., antigens/pathogens not used in the vaccine itself). To investigate whether TDaP-IPV vaccination modulates the immune response to non vaccine target antigens.
This is a multicenter extension study of two European randomized, double-blind studies (V419-007 and V419-008). It describes long-term persistence of hepatitis B and pertussis antibody responses in healthy 4- to 5 year old children previously vaccinated with Vaxelis® or INFANRIX® hexa
This was a dose and formulation ranging study to assess the safety and immunogenicity of SP0173 in healthy adolescents, adults, and older adults in the United States (US). Primary Objective - To describe the safety profile of each SP0173 investigational formulation. Observational Objective: - To describe the immunogenicity of each SP0173 investigational formulation.
This study is being conducted to assess impact of maternal immunisation against pertussis in infants ≤12 months of age before and after introduction of pertussis maternal immunisation in Bogota, Colombia from January 2005-December 2014.
The purpose of this protocol is to generate a set of data that will be analysed by integrated systems biology approach, for validation in subsequent clinical trials or in animal models. 240 healthy participants (18-45y) will be enrolled, 200 will be administered a dose of Boostrix on Day 0, 20 will receive a placebo on Day 0.
The trial includes groups receiving various combinations of meningitis C and pertussis containing vaccines, to be administered concomitantly in adolescents due their school leaving booster vaccinations (as per UK routine immunisation schedule at 13-17 years of age). Immunogenicity and reactogenicity will be assessed.
Young infants are most vulnerable to severe disease and even death when infected with Bordetella Pertussis. The current vaccines and vaccination programs do not guarantee protection of neonates. During the last weeks of pregnancy, maternal IgG antibodies are transferred actively to the fetus. Administration of a pertussis containing vaccine during pregnancy offers protection through high titers of maternal antibodies transferred to the child. Since transplacental transport is immature, infants who are born prior to 37 weeks of gestation, might be vulnerable to pertussis infection even though maternal vaccination was administered, but specific data are lacking. The primary aim of this observational study is to measure whether vaccination during pregnancy offers protection to preterm born infants through higher titers of maternal antibodies, despite immature transplacental transport. Four cohorts of mother-infant pairs will be recruited: term versus preterm born infants, born from either vaccinated women or not vaccinated women. These mother-infant pairs are recruited according to the vaccination status of the mother and to the gestational age at delivery. Pertussis specific antibody titers (anti-Pertussis Toxin, anti-Filamentous haemagglutinin, anti-Pertactin titers) will be monitored in blood samples of the mothers at delivery to measure the possible influence of both gestational age and maternal vaccination status. In order to measure the decline of maternal antibodies in the first weeks of life, blood will be taken from cords as well as from infants at 8 weeks of age, before the first infant pertussis vaccine is administered. Pertussis antibodies to the same antigens will be measured in all infants after a primary series of acellular pertussis vaccines administered at 8,12 and 16 weeks of age and before and after a booster dose in the second year of life. In addition, cellular mediated immune responses will be evaluated in a subgroup of infants before and after a primary series of infants vaccines. A last goal is to measure whether vaccination during pregnancy could offer additional maternal antibodies through breast milk. Again a comparison is made between preterm and term born infants, born from either vaccinated or unvaccinated women. The amount of lactoferrin and pertussis toxin specific IgA in breast milk samples will be measured in samples taken at birth (colostrum), and at several time points afterwards as long as breastfeeding is continued.
