As noted by Ita Here, the effectiveness is adjusted from reported efficacy according to shelf life and defined as "efficacy x shelf-life period in day". The final cost per effectiveness, cost-effectiveness value, is calculated. According to the analysis, the results are shown in Table 1 . According to the analysis, different cost-effectiveness values are derived, and this might be a good data for decision making for selection of appropriate new COVID-19 vaccine for usage in each setting. Nevertheless, the data on the safety and reported adverse effect of the vaccines must be continuously collected for further repeated reappraisal analysis after the post marketing real use.
