Filter by:The purpose of this study is to describe the immunogenicity and safety of Sanofi Pasteur's DTaP-IPV-Hep B-PRP-T fully liquid combined hexavalent vaccine (Hexaxim®) administered at 2, 3, and 4 months of age and at 16 to 17 months of age in infants and toddlers who received a dose of Hep B vaccine at birth or within 1 week after birth. Primary Objective: - To describe the safety profile after each and all doses of Sanofi-Pasteur's DTaP-IPV-Hep B-PRP-T combined vaccine in Vietnamese infants and toddlers. Secondary Objective: - To demonstrate the non-inferiority of the immune response to all antigens induced by the study vaccine in Vietnamese infants one month after the third dose in a 3-dose primary series with the immune response to all antigens induced by the same study vaccine outside Vietnam. - To evaluate the immunogenicity of the study vaccine one month after the 3-dose primary series. - To describe the persistence of all antibodies before receipt of the booster vaccination. - To evaluate the immunogenicity of the study vaccine one month after the booster.
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 from this disease. Maternal acquired pertussis-specific antibodies show low concentrations with short persistence in newborns creating a susceptibility gap for infection between birth and the first vaccinations. A possible strategy to protect infants from birth is pertussis vaccination during pregnancy, which will increase the amount of passively transferred maternal antibodies. However, little is known regarding the effect of high titers of maternal antibodies on the infants immune responses to different pertussis vaccines (whole cell versus acellular). Humoral immune responses will be assessed in infants receiving whole cell versus infants receiving acellular pertussis vaccines. Functionality of the antibodies will also be analyzed.
The purpose of this study is to evaluate the persistence of immune response against the three pertussis antigens (anti- pertussis toxoid (PT), anti-filamentous hemagglutinin (FHA) and anti-pertactin (PRN)) in subjects who received a booster dose of either aP or Tdap study vaccines or Boostrix® during V113_01 study. There was only one Clinic Visit at day 1. Eligible subjects went undergo a single blood draw after which they were observed for approximately 15 minutes. Approximately 10.0 mL of blood was withdrawn. No vaccine was administered and no safety data was collected in this study.
Maternal immunization with tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) is a potential strategy to protect young infants against pertussis before they are fully vaccinated because maternal antibodies may cross the placenta and passively protect her infant. The proposed study is a randomized, blinded, controlled, vaccine trial of maternal Tdap vaccination during the third trimester of pregnancy (Tdap vaccination at 27-36 weeks gestation). Pregnant women will be recruited from the prenatal care clinics at the Hospital Nacional Occidente and the Health Centers in Quetzaltenango, La Esperanza, San Juan Ostuncalco and Concepción Chiquirichapa. Enrolled women and their infants will be followed up until 7 months post-partum.
Primary objective: - To demonstrate the non-inferiority in terms of seroprotection rates (Hib antigen (PRP), Diphtheria, Tetanus, and Pertussis antigens (PT and FHA), and polio types 1, 2 and 3 antigens) of investigational arm (Group A: DTaP-IPV/Hib) versus control arm (Group B: DTaP-IPV and Hib vaccines administered at separate sites), one month after the primary vaccination (all antigens). Secondary objectives: - To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4) in the two study groups (Group A and Group B). - To describe the safety after each dose of each vaccine in the two study groups (Group A and Group B). - To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4 (Group C)
The purpose of this observational study is to evaluate the safety of Tetanus Toxoid Reduced Diphtheria, Toxoid, and Acelluar Pertussis Vaccine (Tdap) in pregnant women at ≥ 20 weeks 0 days gestation receiving Tdap as part of standard practice. Prior Tdap/Td/TT history will be verified by medical record review when possible. There will be an emphasis on enrolling women who have received Tdap before the current pregnancy, to the greatest extent possible. Non-pregnant women who are receiving their initial Tdap will also be recruited. Injection-site (local) and systemic reaction data will be assessed on the vaccination day and during the 7 days following vaccination using either identical web-based or paper diaries, depending on the preference of the study participant. Pregnant women will be followed until delivery with comprehensive obstetric and neonatal outcomes obtained from review of the electronic medical record.
This study is designed to assess the immunogenicity and safety of DTaP vaccine (BK1301) as a booster dose in adolescents. The purposes of this study are as follows: - To confirm the non-inferiority of BK1301 to Adsorbed Diphtheria-Tetanus Combined Toxoid (DT toxoid) with respect to booster responses for anti-diphtheria toxoid (anti-D) and anti-tetanus toxoid (anti-T) antibodies - To confirm that booster responses for anti-pertussis toxoid (anti-PT) and anti-Filamentous Hemagglutinin (anti-FHA) antibodies are more than 80% of participants received BK1301
The purpose of this Registry is to detect and describe any abnormal pregnancy outcomes, including teratogenicity, in females intentionally or unintentionally exposed to Boostrix during their pregnancies in the US. The Registry requires voluntary, prospective reporting of eligible pregnancies by patients and health care providers (HCPs). Data such as vaccination with Boostrix during pregnancy or within 28 days preceding conception, potential confounding factors (such as exposure to other medications) and information related to the outcome of the pregnancy will be collected prospectively
The aim of this study is to evaluate the immunogenicity and safety of a novel DTaP-IPV-Hep B-PRP~T fully liquid combined hexavalent vaccine (study vaccine) administered at 2, 4, and 6 months of age compared to Sanofi Pasteur's DTaP-IPV//PRP~T combined vaccine (Pentaxim™) given at 2, 4, and 6 months of age and Hep B vaccine (Euvax B®) given at 1 and 6 months of age in South Korean infants that received a birth dose of Hep B and born to mothers documented to be serum anti-HBs Ag negative. Primary Objective - To demonstrate the non-inferiority in terms of seroprotection (Diphtheria, Tetanus, poliovirus types 1, 2, and 3, PRP-T, Hep B) and vaccine response for pertussis antigens (pertussis toxoid [PT] and filamentous haemagglutinin [FHA]) of Group A versus Group B, one month after the third dose of combined vaccines. Secondary Objectives: - To further study the immunogenicity of the two vaccination schemes, before the first dose and one month after the last dose of vaccines. - To study the safety after each and any dose of vaccines administered in the two vaccination schemes
The aim of the study is to generate additional safety and immunogenicity data to support the registration of the product in Japan. Primary objectives: - To demonstrate the non-inferiority of SP306 versus DT (DT BIK® 0.1mL) vaccine in terms of diphtheria and tetanus booster response rate (proportion of subjects with booster responses) and seroprotection rate (percentage of subjects with antitoxin concentrations ≥0.1 IU/mL) at 28 days (window 28-35 days) after one injection in Japanese adolescents 11-12 years of age. - To evaluate the immune response of SP306 against the pertussis antigens PT and FHA in terms of booster response rate (proportion of subjects with booster responses) at 28 days (window 28-35 days) after one injection in Japanese adolescents 11-12 years of age. Secondary objectives: - To further evaluate the immune response of the study vaccines against diphtheria, tetanus and pertussis antigens. - To assess the safety of the study vaccines after one injection in Japanese adolescents 11-12 years of age.
