Question

Before the chickenpox vaccination was available, children were often purposely exposed to the virus at

young age. What was the reason for doing this?

Answer 1

ANSWER: Children were purposely exposed to the virus at a young age because once this virus enters in a human body, the body gradually develops immunity and a resistance to this virus, and hence, later after it's cure there are almost no chances of getting the virus of chickenpox again in a same body.
