Chicken Pox

So I think that htere are a few kids in my town that have chicken pox - I alreayd had the chicken pox but what aobut all of those people htat jujst got the vaccination for it - I relaly do not think that that is a great idea to get his vaccination because when you get older and hte vaccine is wearing off in your 30's and 40's you'll end up with shingles or something!
