When I was little, my mother was very insistent that I be up to date on all my vaccinations. The chicken pox and hepatitis B vaccines did not exist, but I got the polio, MMR, and all that other good stuff. My mother had a huge fight with my pediatrician when he tried to tell her that the smallpox vaccine was no longer necessary. (I did not receive the vaccine.)
I got the hepatitis B vaccine while I was in college. I seem to recall that it was free or really cheap.
I had the chicken pox when I was in 4th grade, over Christmas break. I couldn't get it when school was in session so I could miss a week of classes. Nooo... I had to miss Christmas.
