Filters are available below that chart: - *Filter by Continent*: Only show countries in a specific continent (e.g. Asia, North America) - *Filter by Min Population (country as reference)*: Only show countries with specified minimum population, excluding countries with low population. The countries with their population count are for reference. - *Filter by dosage*: Be default, chart shows **fully vaccinated people**. Use this to show people with **at least one dose**. **Data: [Our World in Data](https://ourworldindata.org/covid-vaccinations) (always fetched from source)** Citation: Mathieu, E., Ritchie, H., Ortiz-Ospina, E. et al.
