You may own had a mild crust, you may have a intuitive immunity. Best to check near your doctor. he can to a test to see if you are immune . If you are not, you should own the vaccination. occasionally , associates get seriously in poor health from chicken pox, and you should take lead of the vaccine.
there is no source American children should get chicken pox. in attendance is a vaccine that prevents the disease. talk to your doctor just about a booster shot.
It could mean that you have a mild case beforehand and did not note it, or more possible its because your immune system is too strong for the virus right now. I remember my entire family circle got except for my brother, eventually he get it 10 years later.
