Estimated VE over time. VE was estimated based on the odds ratio of positive SARS-CoV-2 PCR tests and negative SARS-CoV-2 PCR tests, relative to this odds ratio for individuals that just received a first vaccine dose (1 to 6 days after dose 1, left most datapoint). VE was estimated for: 2-dose BNT162b2 recipients (blue), 3-dose BNT162b2 recipients (orange), 2-dose mRNA-1273 recipients (green), and 3-dose mRNA-1273 recipients (red). Error bars indicate 95% CI.
