Congress finds the following:
(1)
A public health emergency regarding the COVID–19 pandemic was first declared on January 31, 2020, and has been subsequently renewed repeatedly, most recently on July 19, 2021, by the Secretary of Health and Human Services under both Republican and Democratic administrations.
(2)
In the spring of 2020, the only tests available to determine whether a person had a recent or prior infection of SARS–CoV–2 were serology tests which could identify whether a person had antibodies specific to the SARS–CoV–2 virus.
(3)
On May 8, 2020, the Centers for Medicare & Medicaid Services (CMS), citing the ongoing COVID–19 public health emergency, issued an interim final rule which recognized on an interim basis that certain Food and Drug Administration-authorized serology tests fall under the Medicare benefit category for diagnostic laboratory tests.
(4)
On March 5, 2021, the Food and Drug Administration issued the first authorization for the emergency use of a cellular (T-cell) immune response COVID–19 test intended for use as an aid in identifying individuals with an adaptive T-cell immune response to SARS–CoV–2, indicating recent or prior infection with SARS–CoV–2.
(5)
CMS has yet to update its May 8, 2020, interim final rule or provide separate guidance to clarify that Medicare coverage extends to other Food and Drug Administration-authorized tests, including T-cell tests, that are intended for diagnosing recent or prior infection with SARS–CoV–2.
(6)
In research and development related to infectious diseases and vaccines, including SARS–CoV–2, historically the antibody response, which is only half of the adaptive immune system, has been the primary tool for assessment.
(7)
The other half of the adaptive immune response, the T-cell response, has historically been more difficult to assess, but scientific and technological advances now allow for standardized and sensitive methods to measure T-cells.
(8)
The National Institutes of Health have integrated T-cell testing into certain studies regarding the impact of T-cells in detecting and defending against SARS–CoV–2 variants, and there exist additional research opportunities regarding the cellular immune response to SARS–CoV–2, including—
(A)
identifying the type and duration of T-cell response that confers immunity (including to variants) following natural infection, vaccination, or both;
(B)
understanding the T-cell response in different populations, including children, the elderly, and immunocompromised individuals; and
(C)
understanding the T-cell response in patients facing long-term COVID–19 symptoms.
(9)
Evidence shows T-cells play an important role in the immune response to COVID–19 and points to the need for a concerted research effort, which could have profound consequences on public health, such as policies on boosters or the development of therapeutics for patients suffering from post-acute sequelae of COVID–19 infection.
