More than 900 million doses of COVID-19 vaccines have been administered across China as of Monday, the National Health Commission (NHC) said Tuesday.

The NHC vowed to ensure a steady vaccine supply and continue to facilitate mass vaccination.

China hit the landmark figure of 100 million vaccinations on March 27. The number reached 200 million on April 20, 300 million on May 7,  400 million on May 16, 500 million on May 23,  600 million on May 28, 700 million on June 2 and 800 million on June 8.

The pace of inoculations has significantly accelerated after fresh locally-transmitted cases were reported in several places across China since mid-May.

China aims to vaccinate at least 70 percent of the target population by the end of this year, according to Zeng Yixin, deputy head of the NHC.
