Extended Data Fig. 1: Longitudinal Omicron/BA.1 and Delta neutralization capacity in Omicron/BA.1 infected participants.

Neutralization of Omicron (blue) and Delta (red) at all study visits. Participant number is as in Extended Data Table 1. Top three rows are participants vaccinated with Pfizer BNT162b2 (n = 8) or Johnson and Johnson Ad26.CoV2.S (n = 7) and bottom five rows are unvaccinated participants (n = 24). X-axis is the time post-symptom onset when sample was collected, and y-axis is neutralization as FRNT₅₀. Dashed line is the most concentrated plasma tested (LOQ, limit of quantification below which FRNT₅₀ values are extrapolated). All participants recovered except participant 29, who died.
