Vaccination records

[rscowboy 0]

As we review the Moscow embassy vaccination requirements, my fiance (46) has not had any shots in the last 10 years and is unable to obtain any records from her past (childhood forward) vaccinations. There are only a couple vaccinations that appear to require current proof (based on the age requirements). I also recall reading somewhere that the true vaccination requirements apply at AOS, after marriage.

Two questions:

Can she avoid vaccinations (until we marry -- ie, after entry under a K-1)?

If the embassy requires vaccinations prior to issuance of the K-1, are just the adult ones required or must she get shots that are childhood shots because she cannot locate her Soviet-era records?

Thanks in advance.
