Countries belonging to the group of BCG⁺FluVac⁻ display the lowest COVID-19 deaths/million and the most delayed transmission of infection: Countries were grouped based on the coverage of BCG and flu vaccination and analyzed for COVID-19 deaths/million and COVID-19 mortality rate. These vast majority of countries were divided into four groups firstly based on the availability or non-availability of BCG or flu vaccination, designated with ‘+’ and ‘-‘ respectively. Next, the groups were further classified based on the extent of coverage of a particular vaccination. Countries with >50% coverage of a particular vaccination were considered having high vaccination and denoted with ‘hi’ whereas countries with <50% coverage were considered having low vaccination coverage and thus denoted ‘lo’. The four major groups were analyzed for mean differences at three different time points: (a). 17^th May 2020, (b). 1^st October 2020. and (c). 31^st December 2020. (d). The major groups out of 83 countries were also compared with respect to the time required for the first 10,000 cases to occur. One-way ANOVA was used to calculate the statistical significance, *p < .05 **p < .01, ***p < .001 and ****p < .0001
