Here we take a look at 10 countries that have administered the most number of COVID-19 vaccine doses per 100 people in the total population as of 21st March 2021. It must be noted that this is counted as a single dose, and may not equal the total number of people vaccinated, depending on the specific dose regime (e.g. people receive multiple doses).

1) Israel --- 112.52
2) United Arab Emirates --- 73.8
3) Chile --- 44.31
4) United Kingdom --- 43.99 (Mar 20, 2021)
5) Bahrain --- 38.39
6) United States --- 37.22
7) Serbia --- 31.89
8) Hungary --- 21.42
9) Qatar --- 20.64
10) Morocco --- 18.12 (Mar 20, 2021)  

The mass vaccination campaign of the United Kingdom and the United States have been most impressive as these countries have relatively much larger populations than other countries listed.

As far as Pakistan is concerned, the country has vaccinated only 0.16 per 100 people (Data till March 14th, 2021). Neighboring countries have been carrying out immunizations much more effectively. India has administered 3.27 COVID vaccine doses per 100 people in the total population, while Bangladesh (2.89) and China (5.21) have also driven their vaccination campaigns at a faster rate.
