a, Genome copies (left) and infectious virus (right) for pre-VOC and Delta unvaccinated patients. Infectious titers (FFU > 0) were detected in 94 pre-VOC and 112 Delta unvaccinated patients; no titers (FFU = 0) were detected in 24 pre-VOC and 15 Delta unvaccinated patients. Error bars indicate mean ± s.d. Two-tailed t-test was used to determined differences of means. *P = 0.0373 and ***P = 0.001. Genome copies (b) and infectious VLs (c) measured for pre-VOC-infected and Delta VOC-infected patients at different DPOS. The solid lines represent the fitted curve calculated using the LOESS method. Error bars represent 95% confidence bands of the best-fit line. LOESS, locally estimated scatterplot smoothing.
