happyforest (1083.2 days ago) i wouldnt tell someone whether to get a vaccine or not, bc i know that they are controversial, but i will tell you that chickenpox is one of those diseases that is worse to get the older you are. you arent `old` at 30, but if you havent had it yet, you could get it later, and just like it would be dangerous to a young child, it would be dangerous for you also.
