Fig. 3: Pseudovirus neutralization antibodies (ID50) to the D614G variant and Omicron sub-lineages at Day 1 (pre-booster) and Days 29 and 91 post-NVX-CoV2373 booster in individuals, stratified by prior exposure to SARS-CoV-2 as detected by N protein.

The spaghetti plot depicts (a) Ad26.COV2.S-primed, (b) mRNA-1273-primed; and (c) BNT162b2-primed participants boosted with NVX-CoV2373. Each line represents the PsVNA at Days 1, 29 and 91 in individuals with detectable anti-N protein antibody by ELISA prior to NVX-CoV2373 boost (red) or without detectable N protein (blue). The dotted gray line depicts the lower level of detection.
