To track the vaccination efforts, I scrapped vaccination data from the web using publicly available data sources.
Data from: Our World in Data, https://ourworldindata.org/.
Location and Date (YYYY-MM-DD) data was last updated:

However, this graph is slightly misleading because it does not put into account the total populations of the Locations being observed, when it comes to the total vaccinations per 100 people the graph looks like this.
