BACKGROUND Infants born at 33 through 35 completed weeks of gestation (33-35GA) are at risk for severe respiratory syncytial virus (RSV) infection, and palivizumab prophylaxis lowers hospitalizations for RSV infection by as much as 80%. The 33-35GA cohort comprises 3-5% of annual births; thus expert panels recommend limiting prophylaxis to situations in(More)
BACKGROUND The tocopherol-based oil-in-water emulsion adjuvant system family (AS03) improves antigen sparing with split-virion H5N1 influenza vaccines, representing an important development for pandemic preparedness. In this phase 1/2 randomized, controlled, observer-blinded study in 680 adults, we assessed the immunogenicity and safety of A/Indonesia/5/05(More)
OBJECTIVE To describe differences in patients hospitalized with respiratory syncytial virus (RSV) lower respiratory tract infection (LRI) at nine Canadian tertiary care hospitals. In addition, this study describes the variation in use of drug and other interventions. METHODS Data on patients hospitalized with RSV LRI and their outcomes were prospectively(More)
BACKGROUND Group A streptococcus (GAS) causes illness ranging from uncomplicated pharyngitis to life-threatening necrotizing fasciitis, toxic shock, and rheumatic fever. Attempts to develop an M protein-based vaccine have been hindered by the fact that some M proteins elicit both protective antibodies and antibodies that cross-react with human tissues. New(More)
The number of deaths attributable to influenza is believed to be considerably higher than the number certified by vital statistics registration as due to influenza. Weekly mortality data for Canada from the 1989/1990 to the 1998/1999 influenza seasons were analysed by cause of death, age group, and place of death to estimate the impact of influenza on(More)
OBJECTIVES To determine the relationship between receipt of aerosolized ribavirin and the hospital course of high-risk infants and children with respiratory syncytial virus (RSV) lower respiratory infection (LRI). METHODS The 1993-1994 Pediatric Investigators Collaborative Network on Infections in Canada (PICNIC) RSV database consists of prospectively(More)
OBJECTIVE We wished to compare outcomes of respiratory syncytial virus (RSV) infection in children with bronchopulmonary dysplasia (BPD) with those with other pulmonary disorders: cystic fibrosis, recurrent aspiration pneumonitis, pulmonary malformation, neurogenic disorders interfering with pulmonary toilet, and tracheoesophageal fistula. METHODS(More)
BACKGROUND Nosocomial urinary tract infection (NUTI) occurs with varying frequency in children and is thought to be associated with urethral instrumentation. In response to changing infection control resources at our facility, we reviewed NUTI to determine whether the frequency of NUTI, associated complications, or presence of a remediable risk factor(More)
CONTEXT Immunization with a meningococcal tetravalent (serogroup ACWY) glycoconjugate vaccine is recommended for all US adolescents. However, the currently licensed vaccine is poorly immunogenic in infancy, when the highest rates of disease are observed. OBJECTIVE To determine the immunogenicity of a novel tetravalent CRM(197)-conjugated meningococcal(More)
