Difficult to determine, the most affected district in China is open again. Now, the world is waiting for them to come and give the vaccine, antidote and any help that will solve this crisis quickly.
Not sure how many people are going to trust a vaccine imported from China. Other drugs are different because you can do chemical tests to determine what they contain but I think vaccines are a little different. There's still a chance also that Europe will come up with some sort of vaccine before the end of this... (I'm not versed in licensing laws they may have to trial it in every customs area).
Valid points.
But some countries that are near to China might not think twice in these times. They'll desperately want to get rid of it and if it's the actual vaccine that helped them to overcome the virus, they might give it a try.
I've heard about Russia and Australia too experimenting for the possible vaccine.
