Filter by:To assess the anti-PRP antibody response one month after vaccination in the groups receiving a fourth consecutive dose of two formulations of DTPw-HBV/Hib vaccine
To evaluate and standardize umbilical cord specimen collection and laboratory procedures to evaluate cellular and serological immune responses in neonates and young infants
The purpose of this study is to evaluate the safety of administering a combination vaccine (DTaP-HepB-IPV; Pediarix™) to infants at birth, 2 and 6 months compared to the administration of a HepB vaccine at birth and the same combination vaccine at 2, 4, and 6 months of age. Additionally, researchers will assess the body's antibody response (proteins produced by the body's immune system that help fight infections) following each vaccine dose. The study will enroll 5 healthy newborns, ages 0-5 days. Participants will be involved in study related procedures for up to 288 days, including blood sample collection and 5 study visits.
The purpose of this study is to evaluate the safety, tolerability, and immune response of an investigational vaccine being evaluated to reduce the incidence of diphtheria, pertussis, tetanus, hepatitis B, poliomyelitis, and Haemophilus influenza type b.
The purpose of this study is to determine if 2 doses of Pneumococcal Conjugate Vaccine (PCV) followed by 1 dose of Pneumococcal Polysaccharide Vaccine (PPV) in HIV-infected children on anti-HIV therapy is helpful and safe in fighting pneumococcal infections in this group of children. This study will also look at the protection provided by childhood vaccination against measles, pertussis, and hepatitis B virus. Pneumococcal infections are the most common AIDS-related infection in HIV-infected children. PCV may help reduce the chances of HIV-infected children getting pneumococcal infections. This study will look at whether pneumococcal vaccines are safe and effective in HIV-infected children receiving HAART. It will look at whether HIV-infected children are protected by childhood vaccines received previously and if more doses are safe and improve protection.
OBJECTIVES: I. Compare the efficacy of 2 acellular pertussis vaccines vs. whole-cell pertussis vaccine vs. placebo in infants living in Italy. II. Compare the relative protection of each of the acellular vaccines vs. the whole-cell vaccine vs. laboratory-confirmed pertussis. III. Assess the relative efficacy of the acellular vaccines with respect to one another. IV. Assess the immunogenicity of acellular vs. whole-cell vaccines in the study population. V. Compare the frequency of adverse events with each vaccine. VI. Compare the frequency of adverse events attributable to the pertussis component in each of the 3 vaccines. VII. Assess alternative laboratory diagnostic techniques for pertussis in estimating vaccine efficacy, i.e., mucosal immune response, DNA probes, or antibody response to other components of the organism. VIII. Assess the relative efficacy estimates of each vaccine, using clinical criteria to compare the relative incidence rates in each vaccine group.
OBJECTIVES: I. Compare the safety and efficacy of acellular 2-component vs. acellular multicomponent vs. whole-cell pertussis vaccine vs. placebo in infants living in Sweden. II. Compare the relative protection of each vaccine against atypical or subclinical pertussis infection. III. Analyze possible laboratory correlates to vaccine protection.
OBJECTIVES: Assess the efficacy of a single infusion of a high titer pertussis immune globulin for the treatment of severe pertussis in children.
