Dave had a bunch of vaccines the past two days. The two I can remember are Anthrax and Small Pox. Man, that Small Pox one is not one to mess with. He'll be dealing with the injection site for weeks. He has to keep in totally dry at all times which he plans to do using duct tape. Thats a tough Army Ranger for ya!!
The injection site will first swell then the next 4 weeks it'll blister, pus, itch and finally heal.
Soldiers with pregnant wives or small children can't get their vaccines until they reach Afghanistan. Kinda makes me nervous wondering what the heck could happen if I was exposed to it. Scary.
