Food Compound May Enhance Vaccine Efficacy in Older Adults

21 Temmuz 2026Science Daily

A naturally occurring compound, spermidine, found in foods like wheat germ, mushrooms, and aged cheese, may enhance vaccine efficacy in older adults. In a pilot study, researchers administered spermidine supplements to individuals over 65 after their third COVID-19 vaccine dose.
Notably, those with initially weak immune responses showed significant improvements in antibody levels and activity against various virus variants.
As the COVID-19 pandemic continues to affect older adults disproportionately, understanding ways to improve vaccine responses is crucial. This study adds to the growing body of evidence that nutrition can play a significant role in immune health, particularly in aging populations.
This research highlights the potential of dietary compounds in augmenting vaccine responses, particularly in vulnerable populations such as older adults. The findings suggest that incorporating spermidine-rich foods into the diet could be a simple yet effective strategy to bolster immunity, especially for those who…
