How does our immune system change as we age, and what role can vaccines play in supporting healthy longevity? In this informative episode of Growing Older Living Younger, Dr. Gillian Lockitch welcomes physician, healthcare executive, and medical writer Dr. Michael Myers for a thoughtful, evidence-based discussion about immunosenescence—the age-related decline of immune function—and its implications for healthy aging. Together they explore how vaccines work, why vaccine recommendations evolve throughout life, and the importance of understanding both the science and the uncertainties surrounding public health recommendations. Listeners will gain practical insights into immune health, healthspan optimization, brain health and aging, and informed healthcare decision-making.
