Vaccination of Older Adults with Dementia Against Respiratory Infections
Jiehui Kevin Yin,
People with dementia are at a greater risk of complications from respiratory infections therefore can benefit
from vaccinations against influenza, pneumococcal disease and pertussis. This review aimed to evaluate the uptake and
impact of vaccination in older adults with dementia against respiratory infections and identify knowledge gaps. Key databases
were explored, search results were assessed, relevant studies identified, and data were synthesised and summarised.
Most available data suggest that older adults with dementia are less likely to receive influenza or pneumococcal vaccine
while a few studies indicate an increase in vaccination uptake but poor immunogenicity. Among dementia patients, community
dwellers have a lower vaccination rate than home care residents. However, vaccinations against influenza and
pneumococcal disease can benefit individuals with dementia by reducing both mortality and morbidity. Health professionals
caring for patients with dementia could play a role in fostering vaccination of these individuals.
