The Phys who took ur examination have these records, they won't just give u in quick fashion, most of img examination have no computer records. but the lab who gives u Vacine also give a small card to keep up to you and you wonn't need these vacince in ur life. may be u missed the vacine or card.
solutions is noone believe on oral claim. so either redone and do mention that u already have done last year so if dosage is important they would take care of it. or try to find the old rec or proof from ur phy office.
Good Luck
