Forums > Living in Kunming > Cant find vaccine certificate of 2nd dose

I received my 1st vaccination shot in Shanghai (I have the certificate) and the 2nd shot in Kunming (near chenggong) but I wasn't given any receipts or certificates of my 2nd shot.
Where can I find information about my 2nd shot received in Kunming? Is there an online database , App (doesn't show on alipay) or should I call the CDC?
