It looks like an ordinary commercial warehouse, only much bigger. When the lights come on, hundreds of thousands of shrink-wrapped boxes of medicines emerge from the gloom, stacked on shelves nearly five stories high. This [warehouse] and several others across the country are part of the $7 billion Strategic National Stockpile, a government repository of drugs and supplies ready for deployment in a bioterrorism or nuclear attack, or ... other major public health emergency. For nearly two decades, the repository has been almost exclusively managed by the Centers for Disease Control and Prevention. That will change under a Trump administration plan to shift oversight of the $575 million program. Public health officials and members of Congress ... worry the move will disrupt a complex process that relies on long-standing relationships. Experts also question whether the administration's plan will politicize decision-making about products bought for the stockpile. The office of the assistant secretary for preparedness and response (ASPR) oversees the process by which the government awards contracts to private biotechnology companies that develop and manufacture medicines. The CDC then is responsible for buying and replenishing the materials. Come October, however, the ASPR will be in charge of choosing the products and then purchasing them for the stockpile. Critics say it will allow biotech companies to lobby for more of their specialized, and often more expensive, drugs to be included.
