O-1 visa and Form I-693 — vaccinations from the USSR: what to do if you don't have documentation?

I received an O-1 visa and am now applying for adjustment of status and ran into Form I-693 — it requires vaccinations. I had them as a child back in the USSR, and of course no records survived. How do people usually handle this situation? What does the doctor do at the medical examination in such cases?

Without any paperwork, a civilian surgeon orders antibody titer tests — these are used to determine whether there is immunity to specific diseases. If the titers are within the normal range, they don’t revaccinate; they simply record the results on the form.

Do these antibody titers take a long time to process? I have an interview in a month — I’m afraid I won’t make it if I still have to wait for the test results.

A month is fine — results are usually ready within 3–7 days. Some doctors don’t order titers for every vaccine at all — that’s their personal practice, not a USCIS requirement. So you should make it to the interview without any problems.
