China prepares for second COVID wave as vaccine stocks rise.

China is expected to face a new wave of COVID-19 cases, with Omicron variant XBB likely to infect around 65 million people weekly by the end of June. The wave could become the country's second-largest, but it will be "largely invisible" due to low rates of testing and reporting. Increased circulation of XBB variants in China and elsewhere is likely to result in the evolution of new XBB variants. Hospitalizations can be expected to rise if variants that combine the transmissibility of XBB with the lung involvement of Delta catch on. People everywhere need to "go back for regular checkups, and bring their kids in for vaccinations."
