Considerably less effective than the ineffective vaccines we have here against contagion. Yeah, China's going to blow up. Xi was hoping to get through a formal reelection before easing up on the zero covid policy. I'm one of the few that thinks they have been honest about the numbers. Hard to lie about numbers and have a zero covid policy. So I'm confident they have little in the way of immunity from disease, only from vaccination and a vaccination that isn't very effective.
