1, find a book for vaccination when I was a child. This original one is the best.
2. If you can't find it, go to the vaccination unit where you were vaccinated when you were a child. If you have a deposit, I can also give you a replacement card.
3. If the above two points fail, you can try to get the vaccination certificate from the vaccination unit, hehe.
If the above reply is helpful to you, please adopt it.
