From: Differences between Frequentist and Bayesian inference in routine surveillance for influenza vaccine effectiveness: a test-negative case-control study

Fig. 1

Point estimates and 95% confidence or Bayesian credible intervals for influenza vaccine effectiveness (VE) for any influenza vaccine in 2015/16 and 2017/18 and for live attenuated influenza vaccine (LAIV) and inactivated influenza vaccine (IIV) among children in 2013/14. Bayesian prior indicates estimated VE prior to collecting each season’s data, based on studies from prior seasons against the specified influenza subtype; Bayesian posterior indicates updated VE estimates after collecting the study data; Frequentist indicates estimated VE based solely on the study data without prior season information
