Im currently living in China with a residence permit and planning to take a 6 week trip back to the US in august. Is there any indication that a vaccine in China or a vaccine in the US will provide any benefit to travel? I’m assuming it’s still going to be a firm “no” but I may sign up for a Pfizer vaccination x2 just in case something changes shortly after.

I am expecting the world to be chaos for international travel for another few years minimum with China being the least likely to end quarantine.
