It’s long been understood that our immune systems get worse as we age.
But, recently scientists conducted a study for a virus that causes a different effect. In the study, the virus can trigger an older persons immune system to fight other pathogens.
The new study was conducted on the virus called Cytomegalovirus, or CMV. Not only does the virus prove helpful, but also very common in humans. According to the CDC, the virus infects one-third of children before they turn five.
