Why is chickenpox bad for adults?

Adults are 25 times more likely to die from chickenpox than children. The risk of hospitalization and death from chickenpox (varicella) is increased in adults. Chickenpox may cause complications such as pneumonia or, rarely, an inflammation of the brain (encephalitis), both of which can be serious.

How long does passive immunity to chickenpox last?
