In Chengdu, capital of southwest China's Sichuan Province that has recently reported a cluster of local COVID-19 infections, parents have been keen to get their children inoculated since the megacity extended its vaccination program to minors in early August.
"The Delta variant is very infectious, and I will feel safe after my kid gets vaccinated," said a Chengdu resident surnamed Chen, who took her 12-year-old daughter to a local hospital for inoculation.
As of Tuesday, more than 3.6 million doses had been administered to minors aged between 12 and 17 in Sichuan, according to the provincial health commission.
China's top medical experts have pointed out that COVID-19 vaccines are effective against the Delta variant.
Shao Yiming, a researcher with the Chinese Center for Disease Control and Prevention, said in a recent interview that although no vaccine can provide 100 percent protection against viral infections, various COVID-19 variants can still be controlled with existing vaccines.
Citing evidence-based studies, Shao noted that China's domestic COVID-19 vaccines can effectively reduce rates of hospitalization, severe cases, and deaths.
Preliminary studies on the latest COVID-19 outbreak in south China's Guangdong Province show that China's homegrown vaccines are effective against the Delta variant, China's top epidemiologist Zhong Nanshan said Saturday.
The protective effect of China's domestic vaccines is 100 percent effective against severe cases, 76.9 percent against moderate cases, 67.2 percent against mild ones, and 63.2 percent against asymptomatic carriers, respectively, Zhong added.
