Hmmm, so vaccines are being put to the test by the Delta variant. It will be very interesting to see if China can bring this new outbreak under control with the tough lockdowns and other public health measures, that were so successful against the earlier strains.

I don't know what the vax rate is in China but if they can't bring Delta under control them Australia is completely forcked.

Hundreds of thousands locked down in China during biggest outbreak in months

By Rozina Sabur

China is fighting its biggest COVID-19 outbreak in months fuelled by the Indian/delta variant while the United States is intensifying efforts to combat the strain which officials believe is more contagious than chickenpox.

Hundreds of thousands of people in Jiangsu province were in a coronavirus lockdown yesterday (Fri) after a cluster of infections were detected in the provincial capital Nanjing.

The outbreak was linked to airport workers who cleaned a plane from Russia this month.

By yesterday, infections were detected in Beijing and five provinces. At least 206 infections across China have been linked to the cluster and the outbreak is geographically the largest in several months.
