BusinessWorld By Bienvenido S. Oplas, Jr. One of the promises or hypotheses of all these hurried vaccines is that as more people are vaccinated, COVID-19 cases and deaths will decline as people will no longer suffer severe cases of infection. Has this been achieved? I personally wanted to see a quantitative answer to this question. I got data on vaccination by country from https://ourworldindata.org/covid-vaccinations. I chose countries with high vaccination rates. Then I checked their respective COVID-19 cases by country from https://www.worldometers.info/coronavirus/#countries. The result is interesting, or confusing. There are countries with high vaccination rates (at least one dose) of 45% to 69% of their total population and yet have rising cases. These are the Seychelles, the Maldives, Bahrain, and Mongolia.
