I can see it poCan anybody shed light on the reasons why China doesn't seem to be working on a vaccine, and seems to have virtually eradicated the covid without needing one? Or if they are working on a vaccine why we hear nothing about it. sing a massive problem for travelling to other countries and I can understand the rationale behind that, for example somewhere like NZ who have virtually eradicated it, but it seems a lot of people will refuse to take it. Will businesses really refuse people when it could impact them?
