TL;DR: The population-based incidence of admission to hospital with laboratory-confirmed pandemic (H1N1) influenza was low in the first five months of the pandemic in Canada and the risk of a severe outcome was associated with the presence of one or more underlying medical conditions, age of 20 years or more and a delay in hospital admission.

TL;DR: This study emphasizes the need for local surveillance for invasive pneumococcal disease before the development and evaluation of protein-polysaccharide conjugate vaccines for children, especially in an era of increasing antimicrobial resistance.
Journal ArticleDOI
Incidence of hospital admissions and severe outcomes during the first and second waves of pandemic (H1N1) 2009
TL;DR: The epidemiologic features of the first and second waves of the 2009 pandemic differed; the second wave was substantially larger and, although the patients admitted to hospital were older and more of them had underlying conditions, a smaller proportion had a severe outcome.
Journal Article
Serum antibody response to pneumococcal vaccine in children with nephrotic syndrome
TL;DR: Pneumococcal vaccine is immunogenic in children with steroid-responsive nephrotic syndrome and may protect these patients from disease due to pneumococcal types contained in the vaccine.
Journal Article
Invasive Streptococcus pneumoniae infections: serotype distribution and antimicrobial resistance in Canada, 1992-1995.
TL;DR: The high frequency of antimicrobial resistance observed requires more complete investigation and confirmation; however, taken from a global perspective, it supports the need to develop better control strategies, including greater use of new and existing vaccines.
