Not necessarily. We aren't all walking smallpox factories because we have a vaccine. Odds are we would cause severe flu like symptoms because colds are so prevelent. And our bacteria would be brutal.

But remember while we still likely carry bits of resistance to shit from eons ago we would also likely get fucked by their
dieases.

It's probably be more likely that you'd catch some weird, pre-sanitation disease and die with your antibacterial compromised immune system.

probably, theres also the chance that your vaccine is different than the type found when you travel back in time

This is the correct answer. You'd probably get smallpox, in fact.
