China prepares for massive XBB variant COVID wave with vaccine rollout

China is facing a new wave of Covid-19 infections that could peak at 65 million cases per week by the end of June, according to respiratory disease specialist Zhong Nanshan. The surge comes about six months after Beijing dismantled its Covid control protocols. The latest omicron variant, XBB, is fueling the resurgence in cases. The Chinese government's response is subdued as it tries to revive the economy and reassure foreign businesses. The government has given preliminary approval to two vaccines aimed at the XBB subvariants, and others could be approved soon.
