BACKGROUND AND METHODS Several conjugate vaccines against Haemophilus influenzae type b have been developed in the search for one that induces protection even in young infants. We evaluated the safety and efficacy of a conjugate vaccine that links the H. influenzae type b capsular polysaccharide to the outer-membrane protein complex (OMPC) of Neisseria(More)
Immunochemical and immunocytochemical techniques have been used to identify and characterize glucagon-related peptides of the rat central nervous system. These peptides show immunoreactivity with antiglucagon sera directed towards the central portion of the hormone, but not with antisera specific for the free COOH terminus of glucagon. Highest(More)
The extent of the H1N1 pandemic has been estimated from case counts and deaths but the proportion of exposed populations with inapparent infections has not been described in detail. We analysed haemagglutination-inhibition (HI) antibody titres of pre-vaccination sera from pandemic vaccine trials conducted in six countries on four continents to provide an(More)
A potentially deadly A/H7N9 avian-origin influenza virus is currently the cause of an ongoing outbreak in China. Preparedness plans have thus been initiated to preempt the spread of this virus, which appears to have substantial pandemic potential. To effectively prevent a pandemic from unfolding, rapid production of an immunogenic vaccine with an acceptable(More)
BACKGROUND AND OBJECTIVES Staphylococcus aureus is a leading cause of infection in patients with ESRD. Clinical and economic outcomes associated with S. aureus bacteremia and other S. aureus infections in patients with ESRD were examined. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Laboratory, clinical, and hospital billing data from a randomized trial(More)
BACKGROUND There is a critical need for an effective Staphylococcus aureus vaccine for the prevention of staphylococcal disease. In this study, we investigated the impact of S. aureus conjugate vaccine comprised of capsular polysaccharides 5 and 8 (CP5, CP8) on nasal colonization with S. aureus. METHODS Healthy adults recruited from one academic medical(More)
BACKGROUND The highest risk for invasive meningococcal disease (IMD) is in infants aged <1 year. Quadrivalent meningococcal conjugate vaccination has the potential to prevent IMD caused by serogroups A, C, W and Y. This phase 3b, multinational, open-label, randomized, parallel-group, multicenter study evaluated the safety of a 4-dose series of MenACWY-CRM,(More)
BACKGROUND Infants are at the highest risk for meningococcal disease and a broadly protective and safe vaccine is an unmet need in this youngest population. We evaluated the immunogenicity and safety of a 4-dose infant/toddler regimen of MenACWY-CRM given at 2, 4, 6, and 12 months of age concomitantly with pentavalent diphtheria-tetanus-acellular(More)
Antibody titers in rabbits immunized with glucagon conjugated to albumin using difluorodinitrobenzene rose rapidly. Under conditions of immunoassay, less than 2 nl of serum from two of four animals and approximately 4 nl from the other two was required to bind 50% of the 10 pg of [125I]iodoglucagon 100 days after immunization. The dissociation constants of(More)
BACKGROUND In the development of pediatric A/H1N1 influenza vaccines, this study was performed to identify antigen and adjuvant doses providing optimal immunogenicity and antibody persistence to ensure long-term immunity after immunization with an adjuvanted A/H1N1 vaccine in children 3 to <9 years of age. METHODS Healthy children (N = 1357) were(More)
