Almost two years since the first case of Coronavirus 2019. Vaccine development in many
countries have been accelerated due to the suffering of COVID-19 pandemic. We analyzed
the daily data related to new cases, new deaths, and vaccinations in United States of
America, European Union, and Japan. Each country or area representing one continent in
order to evaluate the impact of COVID-19 vaccination. We conclude that the vaccination
did help decrease the daily new cases in all those three countries or area at the beginning.
However, due to the group of population who refused to take vaccination, the impact of
the vaccination in controlling the virus decreased as time goes by, situation that happened
in all those three countries or area. We would highly suggest the government in each
country to take all possible action to encourage people to be fully vaccinated as soon as
possible and maintain other practices of COVID-19 infection control.
