Local authorities in China have ramped up mass vaccination drives to contain the latest resurgence of COVID-19 attributable to the highly contagious Delta variant.
The National Health Commission said Sunday that over 1.77 billion doses of COVID-19 vaccines had been administered in China by Saturday.
The country is orderly propelling its vaccination program among senior citizens and minors aged between 12 and 17, on the premise of ensuring safety.
In Beijing, over 90 percent of adults aged 18 and above had been fully vaccinated against COVID-19 by July 20.
A 103-year-old man from eastern Shandong Province was given his first dose of COVID-19 vaccine at home.
Shan Zhigao is the oldest resident to get the jab in his town. Since July 1, a local health center has been sending teams to vaccinate thousands of inhabitants aged over 60.
"Vaccination has been proved effective in COVID-19 prevention," said Zhang Wenhong, head of the Center for Infectious Diseases at Shanghai's Huashan Hospital, Fudan University.
In the latest wave of COVID-19 resurgence, 15 out of 31 provincial-level regions on the Chinese mainland have reported COVID-19 infections.
The total number of confirmed COVID-19 cases on the mainland reached 93,701 by Saturday, including 1,507 patients still receiving treatment.
