Vaccines for elementary school transfers

I will be moving to Los Angeles this spring for an expatriate assignment, and
my two elementary school children will be transferring to a local elementary school.

I was wondering if anyone knows
how to certify vaccines for the transfer process.
I checked the vaccines required for transfer and all of them were already administered in Japan.
In this case, will the Japanese mother-child handbook be proof ？
Do I need to see an American doctor additionally ？
Please let me know if you have any information, anything.
