U.S.C. § 360bbb-3(g)(2)(C)), FDA is reissuing the April 3, 2020 letter with certain revisions.3
Specifically, FDA has revised the April 3, 2020 EUA for clarity and to address concerns about sub-standard products, which includes revising the third criterion for eligibility and adding a process for removal from Appendix A.
