The performance of SNS before and during the COVID-19 pandemic may raise issues of congressional interest The FY2024 HHS Administration for Strategic Preparedness and Response budget request prioritizes funding for sustainment of current product lines and procurement of products previously supported by the Biomedical Advanced Research and Development Authority (BARDA) that lack a significant commercial market, including certain anti-neutropenic drugs necessary to treat acute radiation syndrome. As Congress . As Congress
considers future support for the SNS, it may considers future support for the SNS, it may consider other issues as well, including
 the scope and purpose of the stockpile,
 its long term sustainability,
 the appropriate role of the PHEMCE,
 whether lessons can be learned from similar federal programs,
 whether to clarify the process by which tribal authorities can request supplies,
 how the stockpile inventory is managed, and
 the appropriate role for subfederal stockpiles.
This report provides background information on the SNS, including the authorities, structure, and appropriations history
associated with the stockpile, as well as a review of select issues for Congress.

To address whether the scope and purpose of the stockpile is sufficiently defined in order to meet stakeholders’ expectations compared to the SNS’s actual capabilities, Congress may consider amending the establishing statute to make explicit the role it intends the SNS to play. Other considerations could include the long-term sustainability and whether appropriated resources are sufficient to balance the scope and purpose of the stockpile, including how to balance the life-cycle costs of countermeasures with preparedness goals. Congress may also choose to examine whether to endorse the new PHEMCE Strategy and Implementation Plan or choose to impose a different decision-making structure. Congress may consider whether lessons learned from other federal programs that have analogous stockpiling needs and have implemented unique approaches to meeting them can be applied to the SNS. Tribes, tribal organizations, and urban Indian organizations reported difficulties accessing the SNS during the COVID-19 pandemic. The Consolidated Appropriations Act, 2023 (P.L. 117-328), clarified that the HHS Secretary must consult with and provide assistance to tribal officials related to SNS management and deployment. Congress may consider the SNS’s ability to meet the needs of Indian tribes and tribal organizations during public health emergencies and other emergency situations where SNS contents are requested and deployed. Additionally, Congress may choose to evaluate how the SNS is managed and whether the tools HHS has developed to inform deployment of SNS resources is appropriate. Other congressional options include more explicitly directing HHS to assign operational control of inventory management systems and providing more direction over how inventory data are collected, reported, and shared among jurisdictions. Currently, there is no requirement for state, local, tribal, or territorial governments to maintain their own stockpile of medical and ancillary equipment to prepare for and respond to a health emergency. The Consolidated Appropriations Act, 2023, established a pilot program to support states in establishing, expanding, or maintaining their own stockpiles of supplies necessary to respond to a public health emergency, major disaster, or emergency. Congress may choose to evaluate the efficacy of such a program and whether and how to expand, maintain, or amend such a program. Congress could also consider whether investments made by other ASPR programs in certain vaccine platform technologies may impact how the SNS operates. If successful, these types of platform technologies could reduce the need to store certain quantities of vaccines by enabling rapid development, production, and deployment based on the threat. However, until such technologies are proven successful the SNS would need to stockpile countermeasures to meet its stated objectives.

The Strategic National Stockpile: Overview and Issues for Congress

Some supplies are managed through vendor-managed inventory and user-managed inventory,
otherwise known as pre-positioned caches.31
Vendor-Managed Inventory (VMI)
Replacing expiring SNS supplies incurs a significant cost. To reduce this cost, the SNS has Replacing expiring SNS supplies incurs a significant cost. To reduce this cost, the SNS has
developed the VMI process to have vendors store and manage some SNS supplies, called the developed the VMI process to have vendors store and manage some SNS supplies, called the
vendor-managed inventory program. Under this program, the SNS pays vendors to store and vendor-managed inventory program. Under this program, the SNS pays vendors to store and
manage a specified amount of the product intended for SNS deployment.32 This arrangement manage a specified amount of the product intended for SNS deployment.32 This arrangement
allows the vendor to rotate its product through this inventory on its way to other commercial allows the vendor to rotate its product through this inventory on its way to other commercial
markets. Thus, fresh product remains available to the SNS and the government need not pay for markets. Thus, fresh product remains available to the SNS and the government need not pay for
replacing expired supplies. Delivery of supplies from vendor-managed inventory takes between replacing expired supplies. Delivery of supplies from vendor-managed inventory takes between
24 and 36 hours. 24 and 36 hours.
One of the limitations of the VMI program is the need for a commercial market sufficient to One of the limitations of the VMI program is the need for a commercial market sufficient to
support selling the products before they expire. The size of the SNS requirement for some support selling the products before they expire. The size of the SNS requirement for some
supplies complicates this issue. For example, according to HHS, the SNS requires too much of supplies complicates this issue. For example, according to HHS, the SNS requires too much of
some oral antibiotics for the vendors to rely on commercial marketplace demands to sell them some oral antibiotics for the vendors to rely on commercial marketplace demands to sell them
before SNS deployment or expiration.33 According to GAO, HHS terminated all of its VMI before SNS deployment or expiration.33 According to GAO, HHS terminated all of its VMI
contracts in 2017, citing that they were not cost-effective or were insufficiently meeting other contracts in 2017, citing that they were not cost-effective or were insufficiently meeting other
preparedness goals.34 As part of its COVID-19 response, the SNS began reissuing VMI contracts. preparedness goals.34 As part of its COVID-19 response, the SNS began reissuing VMI contracts.
According to HHS, VMI contracts account for about 10% of current SNS contracts.35 According to HHS, VMI contracts account for about 10% of current SNS contracts.35

The Strategic National Stockpile: Overview and Issues for Congress

Project BioShield increases the stockpile’s maintenance costs, because the products need to be stored and eventually replenished when they expire. Typically, SNS appropriations are used to procure or replenish expiring countermeasures that are FDA-approved, and Project BioShield funds are used to procure or replenish expiring countermeasures that lack FDA approval. However, BioShield funds have been used to replenish some expiring FDA- approved countermeasures, including anthrax vaccine and anthrax antitoxin.50 Increasing costs associated countermeasures, including anthrax vaccine and anthrax antitoxin.50 Increasing costs associated

Investments in other program areas of ASPR may impact how the SNS operates and makes future strategic investments. For example, the FY2024 HHS Administration for Strategic Preparedness and Response budget requests $47 million to support the Biomedical Advanced Research and Development Authority’s (BARDA’s) “mRNA vaccine platform technology to support American Pandemic Preparedness Plan (APPP) goals and cover increasing sustainment costs for manufacturing capacity for pandemic response readiness.”55 BARDA also plans to invest additional resources into its agnostic advanced development portfolio.

Congress may choose to take these considerations into account when determining funding levels
for regular SNS and Project BioShield appropriations.
Shelf Life Extension Program
Various materials maintained in the stockpile—such as medications, vaccines, and some PPE—
have expiration dates. Acknowledging that many medical products may be effective and safe after
their stated expiration date, depending on storage conditions, the U.S. Department of Defense
(DOD) and the FDA established the federal Shelf Life Extension Program (SLEP) in 1986.55 This
fee-for-service program allows for the deferment of replacement costs of specific stockpile items
if they pass periodic FDA stability testing.56 If granted, a Shelf-Life Extension applies only to
products under the same lot number kept in identical storage conditions.

However, until such platform technologies are proven successful, the SNS will need to stockpile countermeasures to meet its stated objectives. Congress may choose to take these considerations into account when determining funding levels for regular SNS and Project BioShield appropriations.

The authorizing statute for the SNS requires in the annual threat-based review that the HHS Secretary shall provide “appropriate protocols and processes for the deployment, distribution, or dispensing of the countermeasure at the State and local level” for each new or modified countermeasure procurement or replenishment.77 Further, preparedness guides indicate that state or territorial health officials and/or governors can request SNS deployment through their respective emergency management agencies in the case of a presidentially declared disaster, or through the appropriate federal emergency operations center in absence of such a declaration, but the guides do not specifically and explicitly indicate how tribal organizations would request SNS deployment.78 70 Defense Logistics Agency, Defense Logistics Agency, Press Release, “DLA’s Warstopper Program Makes Medical Supplies Available for , “DLA’s Warstopper Program Makes Medical Supplies Available for

SNS assets. The authorizing statute for the SNS requires in the annual threat-based review that
the HHS Secretary shall provide “appropriate protocols and processes for the deployment,
distribution, or dispensing of the countermeasure at the State and local level” for each new or
modified countermeasure procurement or replenishment.74 Further, preparedness guides indicate
that state or territorial health officials and/or governors can request SNS deployment through their
respective emergency management agencies in the case of a presidentially declared disaster, or
through the appropriate federal emergency operations center in absence of such a declaration, but
the guides do not specifically and explicitly indicate how tribal organizations would request SNS
deployment.75
