Is it possible that i catch the chickenpox from my daughter's vaccination?

Unlikely: If you're 30 years old, you've probably either had chickenpox or been vaccinated against it, so there should be nothing to worry about.

Depends: If you had never had chickenpox, your exposure to the weakened virus carried by your kid may "vaccinate" you. Your chances of breaking out would be minor.You likely had chickenpox as a kid, and her vaccination would not reactivate your past illness.
