US agency offers legal immunity to Ebola vaccine makers (opens in new tab)

Well, by definition all vaccines start out as experimental ones.

This action is designed to protect companies in their initial Phase 1 safety testings, which for obvious reasons is done with 1st World volunteers before they move to Africa.

Vaccine engineering is also a fairly well understood technology by now.

So on the slight chance the people involved are seriously unethical, you're willing to dice with a disease that could well kill billions prior to discovery/proof of effectiveness, mass production, and mass distribution of a vaccine, all together which will take years at best?
