I was not talking about China and their main method of early control was immediate and harsh lockdowns that are quite difficult to implement and enforce in free societies. It is also not completely gone in China as they have had a recent spat of new cases.The only think that refutes this is that they got rid of it in China without a vaccine. So it is possible...
In addition, without a vaccine, China could easily have issues moving forward as this virus is unlikely to just disappear on it's own - which is why China has already given experimental vaccines to over 1 million healthcare workers and other high risk individuals and plans to roll out a large scale vaccination program.
