Strategic National Stockpile Enhancement and Transparency Act This bill requires the Department of Health and Human Services (HHS) to establish, and award grants to states for the implementation of, the National Emergency Biodefense Network. HHS must coordinate with the Strategic National Stockpile and the National Biodefense Science Board in this effort. The network consists of state entities responsible for tracking and maintaining adequate supplies of drugs, medical devices, and other items necessary for the emergency health security of the United States. The network must be developed and implemented using a private blockchain (i.e., a distributed ledger technology).
