Could a routine vaccine help protect your brain? In this episode, we explore emerging research on the association between shingles vaccination and reduced dementia risk. Ron Swan shares his perspective as a community advocate focused on aging and accessibility, while Dr. Dawn Bowdish (Professor, McMaster University) breaks down what the science says, and what it doesn’t, about how vaccines may influence brain health. Together, they unpack what shingles is and what “promising but early” research about shingles vaccination could mean for reducing dementia risk.

Guests:
Ron Swan is a retired business development professional and entrepreneur with a strong focus on accessibility and aging-in-place. He founded Home Safe Living, a company that provided independent living and accessibility solutions across the Maritime region before selling the business to Lawton’s Drugs, a Sobeys company. A passionate advocate for older adults, Ron continues to contribute through leadership roles, including Chair of the Board of CARP Nova Scotia and past Chair of the Seniors’ Advisory Council of Nova Scotia. He is frequently called upon to speak on aging, accessibility and community well-being.
Dr. Bowdish is a Professor at McMaster University and Executive Director of the Firestone Institute of Respiratory Health. Her research focuses on how aging affects the immune system, particularly how inflammation alters immune cell function and increases susceptibility to infections. Her work also examines how the aging immune system interacts with the microbiome and how these processes influence healthy and unhealthy aging. Dr. Bowdish leads the Preclinical Studies in Aging Laboratory and serves on the Board of Directors of the Lung Health Foundation, where she advocates for improved lung health and research funding for older adults.
