Aging Alters T Cell Function, Weakening Vaccine Protection
Aging Alters T Cell Function, Weakening Vaccine Protection Aging weakens how the immune system responds to vaccines, according to a new study from the Allen Institute published in Nature on Oct. 29. By analyzing more than 16 million immune cells from adults aged 22 to 65 after influenza vaccination, researchers found that aging reprograms memory T Cell function, limiting their ability to support antibody production and defend against infection.
