Abstract
Pneumococcal, influenza and herpes zoster infections cause significant morbidity and mortality in the aging population. Effective vaccines are available in Canada to prevent and minimize illnesses caused by these infections. The purpose of this review is to provide an overview of the epidemiology of pneumococcal, influenza and herpes zoster infections in older adults, as well as available vaccines and recommended immunization schedules. In addition, the benefits of these vaccines on patient outcomes and the role of pharmacists in improving immunization rates are highlighted.
A literature review was conducted to examine the clinical outcomes related to the use of pneumococcal, influenza and herpes zoster vaccines in adults 65 years and older. All 3 vaccines are beneficial in reducing complications of these infections and are well tolerated in older adults. Studies have shown that the uptake of these vaccines remains suboptimal and the burden of illness caused by these infections continues to affect the quality of life of older adults. Pharmacists are well positioned to screen seniors for vaccine indications during routine assessments, as well as provide education to improve patient awareness, vaccine uptake and health outcomes in older adults.
