Hmm. I heard about something similar almost eight months ago, although I don't think it was developed to the point where they could administer it in any widespread amount. In any case, it would need to go through testing, then get approved by the FDA and other similar organizations, and then they would need to be able to find a way to make it affordable and whatnot. Hopefully they can make this available en masse; it'd definitely take away one major cause of fear in today's world, not to mention prevent countless deaths.
