Anti-ageing drugs could fight COVID-19
The human immune system is mind-bendingly complex, and ageing affects nearly every component. Particularly pressing amid the current pandemic is ageing’s impact on the immune system, which can leave people prone to infection and less responsive to vaccines. Some researchers are tackling this by tweaking vaccines to elicit a stronger response in older people, but others are taking a different tack entirely: rather than working with the limitations of the ageing immune system, they are planning to rejuvenate it.
