Add auto-updating values and figures to Vaccines

[rando2]

A few components here:

• We can automate components of this sentence: As of March 6th, 2021, approximately 319 million vaccine doses have been administered in at least 118 countries worldwide using 10 different vaccines using data from https://github.com/owid/covid-19-data/blob/master/public/data/vaccinations/locations.csv
• Can potentially automate global vaccination rate. Will need to pick a date with a lot of data and sum. Data is in daily_vaccinations_raw column in https://github.com/owid/covid-19-data/blob/master/public/data/vaccinations/vaccinations.csv
• Can also potentially add a figure to support this sentence: In North America, the majority of vaccines distributed until March 2021 have been produced by Pfizer-BioNTech and Moderna. Using the data sources above.

There may be a few other possibilities to use these data in this text as well.

I think this might be auto-updated in another manuscript? SARS-CoV-2 has infected over 125 million people and cost the lives of 2.8 million people globally
