6 leading vaccines globally. Which one is the best?

There are several different COVID-19 vaccines in various stages of authorization, approval, and development around the world.

Here is a comparison of the 6 leading vaccines globally, including which countries have authorized or approved each for use.

I follow the topic with interest and I notice that each country tries to cope with the limited number of vaccine doses and to manage the resources as well as possible, offering citizens one or more vaccine options.

How do you see the Vaccine situation in your country?
