Filter by:A multicenter, observational study to evaluate the safety of Euforvac-Hib vaccine for active primary immunization against diphtheria, tetanus, pertussis, hepatitis B and Haemophilus influenza type B in infants.
The objective in this observational cohort study of young adults sampled at three intervals during the academic year is to ascertain if there is carriage of B. pertussis in asymptomatic individuals. We hypothesize that in asymptomatic college students there is no carriage of B. pertussis detectable by polymerase chain reaction (PCR) assay.
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.
Preterm neonates are fragile to infections. Their immune system is immature, yet in France, primary vaccines are injected at two months of age, as in term infants. Recommendations for vaccinations in infants have changed in France in 2013, suppressing the second injection at three months after birth. Preterm and full-term born infants are now vaccinated at two and four months of age, but no data regarding efficacy in very preterm infants have been registered. The investigators hypothesize that two vaccine injections (at two and four months) would be less efficient than three injections (two, three and four months) in very preterm-born infants.
Due to an unexpectedly high number of infant deaths from whooping cough in 2012, the Department of Health acted to protect newborns between birth and completion of primary immunisations, the period with greatest risk of disease. Vaccination of pregnant women with whooping cough vaccine in the third trimester of pregnancy was instigated nationally, so that antibodies produced by the Mum would cross the placenta to the unborn child, giving them passive protection at the most vulnerable time. This antibody transfer has been known for some time but has not been compared between the two whooping cough vaccines being used in pregnancy. Any effect the raised antibody might have on infant responses to the vaccines given in the first few months of life has also not been measured. This is particularly important as the infant immunisations include some of the same components as the whooping cough vaccines, which include diphtheria, tetanus and polio. Previous studies have shown that high levels of antibody prior to vaccination may affect subsequent antibody responses. It is therefore important to assess whether administration of the whooping cough vaccine in pregnancy adversely affects the protection afforded by the infant vaccines, particularly to those which are similar, namely tetanus and diphtheria as well as meningitis C and Hib vaccines which include diptheria and tetanus components in their structures. This study will assess immune responses of mothers and their babies (~200 pairs) to their vaccinations and will allow the comparison of two whooping cough vaccines being used in pregnancy. This will be done by taking small amounts of blood, which is the only way to measure antibody levels (the proxy of the immune response), before and after the vaccinations. A group of unvaccinated women and their babies (50 pairs) will also be recruited to allow comparison of their immune responses.
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
This study will assess the seroprevalence of hepatitis A virus (HAV), hepatitis B virus (HBV) and Bordetella pertussis (B. pertussis) in adolescents and young adults in Mexico.
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.
