There is some kind of adaptation at play, although I think it's likely a social rather than immunological one. The specific mechanisms aren't as important as the fact that the West is generally worse affected by the pandemic. I also didn't take the comment as implying any deliberate ill intent on China's part. European germs decimated indigenous populations whether or not they were spread intentionally. It is an interesting point, although I think if pandemics become more common the West will adapt. As TFA mentioned, a promising vaccine was created in Boston within two days of receiving the digital sequence of the virus DNA (not even a live sample!). As the risks of pandemics become more widely understood, there will be increasing pressure to accelerate vaccine rollout for future events.
