Functional disability and antibody response to influenza vaccine in elderly patients in a Dutch nursing home

摘要

Serological studies have yielded conflicting results about the antibody response to influenza vaccines in elderly people-hence the association of advanced age with declined protection is in question. Differences in subjects' state of health may be one reason for the divergent findings. We therefore investigated the influence of chronic disease, drug treatment, and functional disability on the immune response to influenza vaccine in elderly people.
