While overall immune responses were not significantly changed, older adults who had previously shown little or no vaccine response experienced notable improvements in anti-spike antibodies, neutralizing activity against multiple variants, and memory B-cell responses. The findings suggest that spermidine may help enhance immune resilience in vaccine non-responders by supporting cellular health and autophagy, a key process that declines with age. #LELearn #EDULiveforeverish","meta_description":"Spermidine Shows Promise for Boosting Vaccine Response A 2026 Aging Cell pilot study found that daily supplementation with 6 mg of spermidine was safe and…","key_points":[],"chapters":[],"topics":[],"duration_seconds":240,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/live-foreverish-71917/episodes/353-summary-spermidine-shows-promise-for-boosting-vaccine-response-life-extension/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/live-foreverish-71917/353-summary-spermidine-shows-promise-for-boosting-vaccine-response-life-extension.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
