BACKGROUND This phase II study evaluated the immunogenicity and reactogenicity of primary vaccination with a novel Hib-MenC conjugate vaccine (GlaxoSmithKline [GSK] Biologicals) coadministered with DTPa-HBV-IPV (GSK Biologicals) at 2, 4 and 6 months. METHODS Healthy infants were randomized to receive Hib-MenC coadministered with DTPa-HBV-IPV (N = 117) or(More)
BACKGROUND This phase I/II partially blinded, randomized, dose-ranging study assessed the safety and immunogenicity of a novel human immunodeficiency virus type 1 (HIV-1) vaccine candidate consisting of a recombinant fusion protein (F4) containing 4 HIV-1 clade B antigens (Gag p24, Pol reverse transcriptase, Nef, and Gag p17) adjuvanted with AS01 in(More)
This report describes the genetic and antigenic variability of bovine viral diarrhea virus strains isolated in Belgium. Part of the 5' untranslated region and the 5' end of the gp53 (E2) coding sequence were amplified by PCR and sequenced. Phylogenetic analysis showed that most field isolates segregated into genotypes Ib or II. Only one out of 28 field(More)
BACKGROUND This study evaluated the concurrent use of meningococcal C tetanus conjugate (MenC-TT) vaccine (NeisVac-C) with DTaP-based combinations, according to 2 vaccination schedules, one of which included hepatitis B vaccination at birth (Trial DTaP-HBV-IPV/Hib-097). METHODS Healthy infants were randomized to receive either DTaP-HBV-IPV/Hib (Infanrix(More)
The human immunodeficiency virus type-1 (HIV-1) vaccine candidate F4/AS01 has previously been shown to induce potent and persistent polyfunctional CD4(+) T-cell responses in HIV-1-seronegative volunteers. This placebo-controlled study evaluated two doses of F4/AS01 1-month apart in antiretroviral treatment (ART)-experienced and ART-naïve HIV-1-infected(More)
After a birth dose of acellular pertussis (aP) and diphtheria (DT)aP-hepatitis B virus (HBV)-inactivated polio vaccine (IPV)/Haemophilus influenza type b (Hib) at 2, 4, and 6 months, a booster dose of DTaP-HBV-IPV/Hib at 12 to 23 months induced strong anti-pertussis booster responses. Thus, neonatal aP priming did not lead to immune tolerance to pertussis(More)
Intracellular cytokine staining (ICS) assay is increasingly used in vaccine clinical trials to measure antigen-specific T-cell mediated immune (CMI) responses in cryopreserved peripheral blood mononuclear cells (PBMCs) and whole blood. However, recent observations indicate that several parameters involved in blood processing can impact PBMC viability and(More)
Safety, reactogenicity and immunogenicity of GSK Biologicals' hexavalent DTPa-HBV-IPV/Hib vaccine (Infanrix)hexa) was assessed when used for primary vaccination at 3, 4 and 5 months of age (N = 2163), compared to the separate administration of DTPa-IPV/Hib and HBV vaccines (N = 720). A similar safety and reactogenicity profile was demonstrated for both(More)
OBJECTIVE The availability of a hepatitis A virus vaccine for infant and early childhood immunization could reduce the transmission of hepatitis A virus in the United States. This study evaluated the immunogenicity and safety of a hepatitis A virus vaccine (Havrix, GlaxoSmithKline Biologicals, Rixensart, Belgium) administered concomitantly with(More)
Phase IIb or III HIV-1 vaccine efficacy trials are generally large and operationally challenging. To mitigate this challenge, the HIV Vaccine Trials Network is designing a Phase IIb efficacy trial accommodating the evaluation of multiple vaccine regimens concurrently. As this efficacy trial would evaluate a limited number of vaccine regimens, there is a(More)
