What are the advantages of chickenpox?

Some studies have indicated that the risk of shingles in older adults is reduced by exposure to children who have chickenpox during the adult's life. This results in a boost of immune responses against the virus and delays the waning of immunity which would eventually lead to shingles.

Is getting chicken pox good?

Complications from chickenpox exposure are especially dangerous — and likely — for children under 1 year old, people older than 15 years, and immunocompromised persons, according to the CDC's Epidemiology and Prevention of Vaccine-Preventable Diseases booklet on the varicella virus.
