Guangzhou has suspended residents' personal appointments for the COVID-19 vaccine, and accepts vaccination group appointments for key population and industries first, so as to ensure adequate numbers of medical staff.
Guangzhou have locked down compounds and streets and ordered some travellers to furnish negative COVID-19 test results, as health officials battle to control outbreaks.
All 10 of China's locally confirmed mainland cases on June 1 were in southern Guangdong, the National Health Commission said on Wednesday, seven in the provincial capital of Guangzhou and three in the nearby city of Foshan.
The two cities have ordered home quarantine for residents of some neighbourhoods, and asked people leaving by air, rail or long distance road journeys for proof of a negative COVID-19 test within three days.
The cases have spurred city residents without vaccine appointments to flock to inoculation sites. Crowds have been "severe" at some spots.
