There was a clip I thought I saw on here at one point but it explained that when you create a bioweapon you always create a vaccine in case you are exposed to it. If you are sending soldiers into areas where access to medical care is unlikely and the soldiers may be assaulted with a bioweapon, the purpose of the vaccine is to prepare their body for the encounter so it responds efficiently in the field should they encounter the bioweapon and not have immediate access to medical care. We can argue all day about how that program may have gotten off track and used for fraud, but to do so would require a greater understanding of what is coming into our country (are people being used as bioweapons?) and what people are actually being exposed to. I do not have that information and most would agree we do not have a good handle on the border so it would be a tough discussion.
