Active clinical trials for "Diphtheria"

Primary objectives: To demonstrate that REPEVAX and VAXIGRIP administered concomitantly in subjects 60 years of age and older are at least as immunogenic as REPEVAX or VAXIGRIP administered separately. Secondary objectives: •Secondary immunogenicity objectives: To describe the immune responses 28 days after concomitant or separate administration of REPEVAX and VAXIGRIP in subjects 60 years of age and older To describe the immune response of VAXIGRIP according to European Medicines Agency criteria in subjects 60 years of age and older (Note for Guidance, 1997: 28) •Secondary safety objective: To describe the safety profile after vaccination in each group

This study will evaluate the safety and efficacy of 9 different vaccines containing aP (acellular pertussis) and TdaP (acellular pertussis, tetanus and diphtheria) in healthy subjects 18 to 40 years of age.

This study will evaluate immunogenicity, safety and tolerability of fully liquid pentavalent vaccine (DTwP-Hib-HepB Vaccine) in infants 6-8 weeks of age.

The purpose of this study is to describe the safety and immunogenicity of repeat administration of Adacel vaccine approximately 10 years following initial administration of the vaccine. Antibody levels prior to revaccination will also be used to characterize antibody persistence following initial vaccination 10 years earlier. Primary Objectives: To compare seroprotection rates against tetanus and diphtheria induced by Adacel vaccine to those induced by Td Adsorbed vaccine. To compare booster response rates against tetanus and diphtheria induced by Adacel vaccine to those induced by Td Adsorbed vaccine. To compare anti-pertussis geometric mean antibody concentrations (GMCs) induced by Adacel vaccine to the GMCs induced by Daptacel® vaccine given to infants. Secondary Objectives: To describe the rates of immediate reactions, solicited reactions, unsolicited adverse events (AEs), and serious adverse events (SAEs) following vaccination with Adacel or Td Adsorbed vaccine. To describe booster response rates for pertussis antigens following revaccination with Adacel vaccine.

The purpose of this study is to look at the safety and immunogenicity of a combination vaccine that includes tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap). The study will be conducted in 48 pregnant women and 32 non-pregnant women. Safety of the newborn infant and the effect of the mother's vaccination on the infants' immune responses prior to vaccinating infants with another combination vaccine to protect against diphtheria, tetanus, and pertussis will be evaluated. Participants will be 18-45 years old. Pregnant volunteers will be 30-32 weeks pregnant and at a low risk for pregnancy complications. Pregnant volunteers will receive 2 injections (1 vaccine and 1 placebo, inactive substance); non-pregnant volunteers will receive 1 injection of vaccine. Blood samples will be collected from the mother and infant, along with the baby's growth measurements. Participation for mother infant pairs is about 15 months and about 7 months for non-pregnant women.

The purpose of this clinical trial is to describe the safety and immunogenicity of one or two doses of Menactra® (TetraMenD) administered in children less than 2 years of age. Primary Objective: To describe the immunogenicity profile of one or two doses of Menactra® (TetraMenD) when administered to subjects aged 9, 12, 15, or 18 months in comparison to the immunogenicity of one dose of Menomune® when administered to children aged 3 years to <6 years of age.

Primary Objectives: To present the safety profile after a 5th dose of DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™. To present the pre-Dose 5 and post-Dose 5 antibody responses to the antigens in DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™. Observational Objectives: To compare under equivalence criteria the pre-Dose 5 and post-Dose 5 antibody responses to the antigens in DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™. To present the pre-vaccination anti-poliovirus GMTs and seroprotection rates. To present the post-vaccination anti-poliovirus GMTs and seroprotection rates among subjects receiving a 4th dose of IPV concurrently with the 5th dose of DAPTACEL and a 2nd dose of MMR.

The present clinical study will assess the immunogenicity and reactogenicity of the subsequent administration of Aventis Pasteur's DTacP-IPV//PRP~T combined vaccine (PENTAVAC™/PENTAXIM), as a three-dose primary vaccination in 6, 10 and 14 weeks of age schedule followed by a booster vaccination during the second year of life with the aim to cover the WHO EPI primary vaccination schedule at this age for diphtheria, tetanus, pertussis, poliomyelitis and Hib vaccines. WHO EPI vaccination schedules for hepatitis B (either 0, 6 and 14 weeks or 6, 10 and 14 weeks of age) will be also assessed in infants born to HBsAg seronegative mothers. To assess the safety of Pentaxim.

This study was designed to assess the lot comparability of DAPTACEL, as well as the safety and immunogenicity of DAPTACEL when co-administered with other recommended infant vaccines. Stage I Primary Objectives: To assess the lot-comparability of immunogenicity of DAPTACEL by when co-administered with other recommended vaccines. To compare the immune response to DTaP-IPV/Hib (Pentacel) with those of three lots of DAPTACEL when co-administered with other recommended vaccines. To compare the immune response of PRP-T antigen in Pentacel with that of ActHIB concurrently administered in a different injection site with DAPTACEL when these vaccines are co-administered with other recommended vaccines. Stage II Primary Objectives: To compare the immune response of DAPTACEL when the 4th dose is co-administered with Hib or other infant vaccines. To compare the the immune response of Pentacel with those elicited by DAPTACEL when co-administered with ActHIB in toddlers.

The present trial is a follow-up of AL203 study (NCT00343889). Primary Objectives: To describe the antibody persistence at 15 to 18 months of age and the booster effect of a dose of DTaP-HB-PRP~T or Tritanrix-HepB/Hib™ (given concomitantly with Oral Polio Vaccine [OPV]). Secondary Objective: To describe the safety profile of a booster dose of DTaP-HB-PRP~T or Tritanrix-HepB/Hib™ when administered concomitantly with OPV in each vaccine group.
