UC immunization deadline?!

Hi guys I’m wondering what would happen if you fail to complete the immunization form before the deadline on August 1st?
The reason I’m asking this is because I will be out of the country until mid August and I don’t have my immunization record with me.

I couldn’t find anywhere online about the consequence of failing to provide the immunization form, what would the school do in that case? Would they rescind their admission decisions?

any input is welcomed and appreciated!

P.S I’ve already emailed the school about accepting foreign documents as proof for immunization record and so far I haven’t heard back.
