An additional one to three doses of hepatitis B vaccine are recommended for nonresponders to an initial standard three-dose series. We compared the safety and immunogenicity of an investigational hepatitis B surface antigen vaccine (HBsAg-1018) with a phosphorothioate oligodeoxyribonucleotide adjuvant that targets toll-like receptor-9 to a commercially(More)
BACKGROUND Because adolescents and adults act as a primary source of pertussis infection for infants, vaccination of mothers immediately postpartum is a potential strategy to reduce transmission (cocoon strategy). For this to be effective, high levels of antibodies must be achieved rapidly after vaccination. We sought to determine whether the antibody(More)
BACKGROUND More severe influenza disease and poor vaccine immunogenicity in HIV-infected patients necessitate improved immunization strategies to maximize vaccine efficacy. METHODS A phase III, randomized trial was conducted at 4 Canadian sites. Two dosing strategies (standard dose vs standard dose plus booster on day 21) were assessed in HIV patients(More)
Healthcare workers' (HCWs) knowledge, attitudes, and beliefs regarding pertussis immunization were assessed and compared to the rate of vaccine uptake. A questionnaire was distributed to employees at a paediatric and maternity tertiary care centre. Respondents were then offered a dose of the tetanus, diphtheria, and acellular pertussis vaccine (Tdap) at a(More)
During the 2013/14 influenza season in Canada, 631 of 654 hospitalisations for laboratory-confirmed influenza enrolled in sentinel hospitals were due to Influenza A. Of the 375 with known subtype, influenza A(H1N1) accounted for 357. Interim unmatched vaccine effectiveness adjusted for age and presence of one or more medical comorbidities was determined by(More)

Interim estimates of 2014/15 influenza vaccine effectiveness in preventing laboratory-confirmed influenza-related hospitalisation from the Serious The 2014/15 influenza season in Canada has been characterised to date by early and intense activity dominated by influenza A(H3N2). A total of 99.0% (593/599) hospitalisations for laboratory-confirmed influenza(More)
BACKGROUND Concern arose in 2010 that reactogenicity, particularly febrile seizures, to influenza A/H1N1-containing 2010-2011 trivalent seasonal inactivated influenza vaccine (TIV) could occur in young children who had been previously immunized and/or infected with the pandemic strain. We conducted a pre-season study of 2010-2011 TIV safety and(More)
BACKGROUND Two pentavalent infant vaccines that contain either 5 or 3 component acellular pertussis antigens are authorized in Canada. Because of changes in vaccine use by provinces over time and movement of families across jurisdictions, it is possible that children are exposed to different combination vaccines during the primary infant immunization(More)
Tetanus, diphtheria, and acellular pertussis vaccine (Tdap) is recommended for all adults in Canada but uptake is low. This study measured the knowledge, attitudes, beliefs, and behaviors of Canadian adults to identify potential barriers and facilitators to Tdap uptake. A survey was undertaken on a geographically representative sample of Canadian adults(More)
