Freshmen in ludong university said that they should bring vaccination certificates when reporting for duty. What if they don't? Do you really need a new injection? Voluntary or compulsory?
Just go to the local health department and get a new certificate. I see. Every year, the school will give you a new vaccination. It doesn't matter whether you have a vaccination certificate or not. School is not bad. After school starts, you will be tested for antibodies. I will supplement it for you according to the situation. Be sure to bring something to prove your identity and a few more photos.
