ĭespite recommendations for uptake of PPV in seniors and a target goal of 80% immunization rate among adults aged 65 years or older by the year 2010 in Canada, immunization rates remain low with only 42% of Canadians over 65 years of age reported being vaccinated. While the efficacy of the pneumococcal vaccine in preventing pneumonia remains inconclusive, there is evidence that administration of the vaccine can play a critical role in reducing the severity of the disease among older adults. PPV is 50-80% effective in the prevention of invasive pneumococcal disease among immunocompetent patients. The pneumococcal polysaccharide vaccine (PPV-23) immunizes against 23 strains of the pneumococcus bacteria. The most common causative pathogen worldwide of CAP is Streptococcus Pneumoniae, accounting for approximately 30-50% of all cases. Seniors with cardiopulmonary disease, poor functional status (such as limitations with activities of daily living), weight loss or recent changes in weight are at increased risk for CAP. Furthermore, case fatality rates of pneumonia with invasive pneumococcal disease increase sharply from 20% (for person 65 years or older) to 40% (for persons 85 years or older). CAP is a leading cause of hospital admissions and mortality in Canada and with increasing age, there is a corresponding increase in morbidity and loss of independence for older adults. With the pending demographic influx of seniors, the prevalence of CAP is expected to substantially increase, resulting in a greater burden for older adults, their caregivers and the health care system. In Canada, CAP poses a considerable threat to the health of older adults and the incidence of CAP almost triples among those aged 65 years or older. Community-acquired pneumonia (CAP) refers to pneumonia acquired outside of hospitals or extended-care facilities.
