It is better to have that book. Otherwise, you have to re-take all the immunizations (Td, MMR, Hepatitis B, Varicella). You can't finish all of them in one visit. It takes many months to finish. However, according to my understanding, as long as you promise to finish the rest of the shots, the doctor will clear you. He will mark the "applicant is not current on immunization..." on the I693 form. But I think it should be ok.
Your university here in US should have your immunization record on file. You can ask them for a copy.
