“Look, the chicken pox vaccine comes with some risks. The chicken pox vaccine is a live attenuated vaccine. It can cause a mild case of the chicken pox or shingles. Plus, it’s not necessary.

And if a pregnant women gets chicken pox, a lot of really nasty things can happen to her baby. I know it takes two shots, I know you don’t want to spend the money, and I know you hate shots. But you really ought to get vaccinated, for yourself and for the other people here at work.”
