Chickenpox (varicella) was once considered a rite of passage for most children. Before routine chickenpox vaccination, virtually everyone had been infected by the time they reached adulthood, sometimes with serious complications. Today, the number of cases and hospitalizations is down dramatically.
However, when chickenpox does occur, it's highly contagious among people who aren't immune. Most people think of chickenpox as a mild disease — and, for most, it is. Unfortunately, there's no way to know who will develop a severe case.
The chickenpox vaccine is a safe, effective way to prevent chickenpox and its possible complications.
