15. Because back in the day, that was how parents thought they could stop an epidemic from continuing.

This is how my mom explained it.
First kid that gets serious measles, every kid in the neighborhood who didn't have measles yet gets sent over for a sleepover with pot-luck and drinks.
After the sleepover, the measles house is quarantined for two weeks.
Then one of two things happens:
- If you went to the party and no one in your household had measles, or if someone is bedridden due to a serious health condition you get quarantined with the rest of the measles house and has to stay there through quarantine. Fun.
- If you went to the party and most of your family had already had or already gone through a quarantine, you returned home and your house was pretty much quarantined for a week to see if you become symptomatic. However, any infant or adult in your house who had never had measles, or has an internal organ or chronic health problem but is not bedridden needs to leave before you can come home from the party and don't come home until the all clear.

My parents went through that; they also never put me or my brother through that, because vaccination, treatment and quarantine procedures had advanced significantly from the time they were kids.

On edit - both my parents knew kids who never came out of quarantine or came out blind, deaf, or with organ or nerve damage from measles. In the 1960's, I had a classmate die and her older sibling go blind from measles because their parents weren't concerned about vaccinations.
Measles is a FAFO disease.
