Adding Middle East Respiratory Syndrome to the FDA Priority Review Voucher Program Act This bill amends the Federal Food, Drug, and Cosmetic Act to include Middle East respiratory syndrome under the priority review voucher program for tropical diseases, which awards a voucher to the sponsor of a new drug or biological product that is approved to prevent or treat a tropical disease. (A voucher entitles the holder to have a future new drug or biological product application acted upon by the Food and Drug Administration within six months.)
