While thankfully C19 is apparently at a low level on the mainland compared to Influenza, mycoplasma and RSV, but numbers are rising driven by JN.1
But China CDC appears to be minimising the risk.
Since JN.1 is growing fast the whole world over (now dominant in USA), much more caution is needed. Especially as the latest pre print shows the old boosters no longer protect against hospitalisation!
The news is that American hospitals are being overrun!
China needs the new XBB variant vaccines for all, not just in certain cities.
