Analysis of Herd Immunity Using Vaccination and Recovery Data Sets

The Covid-19 pandemic that created a situation of public health emergency worldwide called for an urgent requirement of vaccine to prevent further spread of the disease. Successful vaccines started coming into view publicly since December 2020 with Pfizer-BioNTech vaccine being the first with a 95 percent efficacy. The primary purpose of the research is to conduct a statistical analysis of the effect of the covid-19 vaccines on herd immunity. Different countries that have used similar vaccines have been paired and analyzed based on the number of the new cases, recovered cases and the amount of vaccines taken. A comparative study on the herd immunity of the countries before and after the intake of the vaccination is made, to analyze the effect of the vaccines.
