China prepares for new wave of COVID cases from XBB variant, raising global concerns.

China is preparing for a new wave of Covid-19 cases caused by the XBB variant, which is expected to peak in June and infect up to 65 million people per week. Two new vaccines for the XBB variant have received initial approval, with three to four more expected to be approved soon. While officials say the new wave will be less severe, public health experts recommend an aggressive vaccine booster program and a ready supply of antivirals to prevent another spike in deaths among China's large elderly population. Restrictions like those seen during the "zero covid" policy have not been revived, and most residents appear to be continuing life as usual.
