Lyme vaccine?

Don't know much about this, but how would I know if I got a Lyme vaccine (if it even exists) when I was younger? And if I did, could this be producing false positives on the Lyme c6 peptide test and western blots?

Thanks, I definitely do not have them or know where to get them if I got the vaccine 20 years ago.

There's an Ospa vaccine for Lyme. And I recently tested positive on IgM 31 band (Ospa) which doesn't make sense since I would have chronic Lyme but it does make sense if I received the vaccine for Ospa since I think this will make a positive result.

Good news is from my reading the Lyme C6 peptide test is very good because even if you have the vaccine, it will not produce a false positive and I tested positive for this twice.
