Also, September 10th (tomorrow) is verified by hospital vaccination staff at Calmette.

A friendly reminder for those who got vaccinated on August 20, your second Sinovac jab at Calmette International Hospital is tomorrow. Remember to bring 100 rmb cash. For those taking subway, get off at Linyu Qiao Station of Metro Line 2.
