You need to get your antibody titer checked.

There’s no other way to check whether a vaccination worked in causing immunity, and no other way to tell whether you still have sufficient immunity.

In most cases a fresh vaccine course will yield sufficient protection against infection.

Also: the bats do need to bite you. Any other contact doesn‘t risk infection.

If bitten depending on your local health care system they will either determine tigers to see whether you have sufficient immunity, or do a refresher course of the vaccination, with or without immunoglobulin depending on further circumstances (immunocompromised, vaccination a decade old etc)
