Vaccine Nationalism During the COVID Pandemic?

Vaccine nationalism is a word-related problem. People are not realizing the fact that everybody has to do that. You can only control the pandemic. Most vaccine doses in 2020 and 2021 were estimated to be produced in rich countries like the US or South Korea. Each of these pharmaceutical companies had agreements to sell their vaccine depending on what they were getting from each other. And so now, I'm pretty sure they're alarmingly new for all those poor countries who actually unfolded during the COVID pandemic.
