Researchers found that taking a daily spermidine supplement improved vaccine responses in older adults. The study involved 40 healthy adults aged 65 and older who received their third COVID-19 vaccination. Spermidine reduced biological signs of immune system aging, making it easier for the body to fight infections and respond fully to vaccines.
The immune system becomes less efficient as people grow older, making it harder for the body to fight infections and respond fully to vaccines.
A naturally occurring compound called spermidine may help strengthen vaccine responses in some older adults. Spermidine is produced naturally by human cells and is also present in foods such as wheat germ, mushrooms, parmesan, and cheddar. Researchers from the Max Delbrück Center and the University of Oxford led a study to investigate whether spermidine could improve vaccine responses in older adults.
The researchers enrolled 40 healthy adults aged 65 and older who received their third COVID-19 vaccination. After receiving the vaccination, participants took either six milligrams of spermidine or a placebo each day for 13 weeks. The results showed that taking spermidine improved several measures of immune response following COVID-19 vaccination.
The study found that spermidine reduced biological signs of immune system aging and increased autophagy, a natural recycling process that allows cells to remove damaged material and maintain normal function. Autophagy is a key process in cellular maintenance that becomes less active with age. The researchers also found that spermidine lowered markers associated with immunosenescence and increased autophagy.
The study's lead researcher, Dr. Katja Simon from the Max Delbrück Center, said, 'Many older adults respond well to vaccines, but some do not develop strong protection, even after repeated vaccination. Biological aging of immune cells may be one reason why this happens.' The researchers caution that larger studies are needed to determine whether spermidine can consistently improve vaccine responses and whether similar effects are seen with other vaccines.
Why It Matters
This study is important for older adults in India who want to stay healthy and protected from diseases. As the population ages, it's essential to find ways to improve vaccine responses in this age group. Spermidine may be a potential solution to help older adults respond better to vaccines.
Key Facts
- Spermidine is a naturally occurring compound produced by human cells and found in certain foods.
- The study involved 40 healthy adults aged 65 and older who received their third COVID-19 vaccination.
- Participants took either six milligrams of spermidine or a placebo each day for 13 weeks.
- Spermidine reduced biological signs of immune system aging and increased autophagy in the study participants.
- Larger studies are needed to determine whether spermidine can consistently improve vaccine responses.
Key Terms
- Immunosenescence
- The gradual decline of the immune system with age, making it harder for the body to fight infections and respond fully to vaccines.
- Autophagy
- A natural recycling process that allows cells to remove damaged material and maintain normal function.
Implications
