Fast forward, 1 year from now, let's say a "safe" vaccine becomes available for the Covid-19 virus.
Is it possible that, for example, it will work only for a human being in Russia, Italy, and Africa, but not for people in the USA, México, Brazil, etc?

The short answer is yes, it could have varying efficacy, but it is unlikely to be due to location. Preexisting conditions can effect the efficacy of vaccines. Second, there are likely to be several vaccines, all of which are likely to have varying efficacies.
