  1. The estimates are obtained from the fits to the serology data from 2020 shown in Fig. 1. Numbers in the parenthesis indicate 95% credibility intervals of the estimates, obtained by taking the 2.5% and 97.5% quantiles of the posterior probability of the bayesian fit
  2. aEstimates for the youngest ages may be underestimated by the assumption of a logistic relation between age and severity, see section S1 in Additional file 1 for further discussion and complementary estimates
