Then the option would be to make the vaccination mandatory. CCP doesn't like to do unpopular things, but the lockdowns are not popular either.
China also requires everyone to have an app which gives you a color coded status based on the results of COVID tests taken by you and by those in your family and neighborhood, which defines what activities you’re allowed to engage in and what areas you’re allowed to access. Basing that off vaccination status would be far more palatable and would be far less disruptive.
