Chinese authorities are targeting students as part of their latest vaccination campaign, as China sees its biggest virus surge in months.
A vaccination campaign for minors aged 12 to 17 is being expanded to try and combat the spread of the highly contagious delta variant.
The latest cases have now spread to at least 16 provinces and municipalities.
It is unclear how many in China are fully vaccinated, although authorities say more than 1.6 billion doses have been administered so far, BBC reported.
China's Ministry of Education has asked local authorities to implement a programme targeting vaccinations of school students.
Several provinces are already giving school students the jab, but the pressure is on to achieve the government's target of having 80 to 85 percent of the entire population vaccinated by the end of the year.
