Why this App?

This web application is intended to help people interested in following COVID-19 vaccination trend across countries. Data are constantly up-to-date (thanks to “Our World in Data”) and can be visualized in a customizable plot or downloaded after selection of:

  • Countries of interest
  • Dates
  • Number of vaccine doses received by each person:
    • “All” includes partially and fully vaccinated people
    • “Fully” refers to people who completed the vaccination course

In the plot, for better comparison between countries, data are shown as a percentage of the total country population, but hovering on it allows to see the actual number of vaccinated people.
Moreover, mean global values for partially and fully vaccinated people are shown as a grey area on the plot, and can be downloaded as well in a separate tab.

App is hosted at https://elenena810.shinyapps.io/covid_vaccine_world

R code for this app can be found on GitHub
