Abstract: Senior citizens who continually misplace their glasses can still recall childhood episodes in vivid detail. The immune system's "memory" seems to age similarly, according to new work. The study shows that immunological memories etched early in life persist, but those established in old age fade. The findings could explain why vaccines often are ineffective in older folks.
