Birth Certificate: you will need to go to the local police station in China(pai chu suo) or your parents work place to get the Dang An(which ever one has it.) Then go to the local notary office to get it notarized, they will do the translation. For the vaccination, you can call the immigration appointed Dr. to get the information(list). The relationship between you and your parents should be supported by your birth certificate which you should already have when you applied for green card and US citizenship.
