so I had my blood test and am immune to chicken pox, MMR and even though I have had my Hep B shots before they didn't take and I didn't show any immunity to it. The GP said that sometimes it happens. So I had another hep B shot just to see if this one works and I also had meningacocyl (sp?). I have to go back for the tetnus booster one and also polio next month. Gosh the taste in my mouth after I had the shots was just disgusting!!!!!
