Vietnam closed their borders, kept kids home from school, had a month-long lockdown in April, and stopped COVID in its tracks. No magic immunity required, they just did the few things that were necessary to top the spread of an infectious airborne disease. They lived through SARS, everyone knows the consequences of failure to contain a new virus. There's no need to look for explanations in exposure to bat coronaviruses when there's so much Vietnam did that the USA, UK and Europe didn't do. This isn't just about government actions, but the individual actions of the population too.
