The FDA’s emergency use authorization (EUA) program is still active in the area of tests and test kits, which is due in part by the emergence of the Delta variant of the SARS-CoV-2 virus and the associated warnings that the effectiveness of vaccines may be declining. One example of the sustained emphasis on testing is the EUA granted to Thermo Fisher Scientific Inc. for two PCR test kits that can detect the latest variants of the virus, a demonstration that the demand for these updated tests seems unlikely to ebb anytime soon.
