You might have a situation where countries outside of China can decide whether or not to take a vaccine that was produced through in a process where prisoners were volunteered against their will and thus publicly affirm that they are fine that China does such things with their prisoners or let thousands of people die in their countries while public pressure builds up to accept the Chinese vaccine.
To me that seems like a good position for Xi to be in politically and not a problematic scandal.
