Fig. 1: Posterior predicted trajectories (95% credible interval) of anti-spike IgG levels from 28 days post-first dose by prior infection status.

From: SARS-CoV-2 antibody trajectories after a single COVID-19 vaccination with and without prior infection

a 59,101 participants who received at least a single ChAdOx1 vaccination. b 35,638 participants who received at least a single BNT162b2 vaccination. c 2597 participants who received at least a single mRNA-1273 vaccination. Plotted at reference categories: 50 years, female, white ethnicity, not reporting a long-term health condition, not a healthcare worker, and deprivation percentile = 60. Black dotted line shows the upper quantification limit of 450 BAU/mL. Orange dotted lines in panel a and b were predicted trajectories starting from 21 days post-second dose for 92,584 and 51,034 participants who received two ChAdOx1 and BNT162b2 vaccination without prior infection reproduced from our previous analysis, plotted at the same reference categories16. m1273-RNA was not included in this previous analysis due to insufficient data at the time.
