We agree with the authors that it is essential to conduct rigorous preclinical testing of low dose radiation therapy. With old but relevant clinical data and research suggesting anti-inflammatory effects of radiation at very low doses that may affect key inflammatory cells involved in the hyper-inflammatory host response to COVID-19 [9], we do not agree that preclinical studies are require for radiation therapy and should be treated differently than the other therapies being tested. ./cache/cord-314889-lo3kkrfp.txt ./txt/cord-314889-lo3kkrfp.txt
