China publishes how many doses administer each day without breaking down how many people have fully vaccinated. However, it does ocassionally release the total number of people who receive at least one dose. Just a few days ago, Chinese official mentions that over 600 million people receive at least one dose.Seriously, don't know why China isn't publishing statistics on how many shots broken down by first shots and second shots. Every country is doing it. I thought Sinopharm and Sinovac were single shots but apparently they are double shots. This info shouldn't be hard to collect too.
As for the reason why China doesn't break down the number, China has many different vaccines. Sinopharm(2), Sinovac, and Shenzhen Kangtai all are two doses inactivated vaccines, CanSino is one dose viral vector vaccine, and Zhifei is three doses subunit vaccine. In the end of the day, it is difficult to keep track of how many people who got fully vaccinated until much later.
