Table 1.

Assay characteristics of select vaccine, convalescent plasma, and variant entry inhibition studies [1, 2, 3, 4, 5, 6, 7,8^••,9^•,10, 11, 12, 13, 14, 15, 16, 17, 18,19^••,20, 21, 22, 23, 24]

To facilitate interpretation of the studies included in these tables, the characteristics of the studies have been color coded within each category and further annotated for additional information. Abbreviations for live or pseudotyped virus: P (Plaque Reduction Neutralizing Titers or PRNT), F (focus forming units or FFUs), RG (Reporter Genome), MN (Microneutralization), LV (Lentivirus), ΔG (VSVΔG), rV (replication competent VSV), or other. Cell line abbreviations: Vero-C/E (CCL81 or E6; when absent, this indicates that the study did not denote the clone utilized), 293T-A (ACE2 stably expressing; A^# denotes 293Ts transfected with ACE2 before infection), 293T-AT (ACE2 and TMPRSS2).
