It's possible, but still not likely. Over the years, this has probably happened before--she's likely to already have been exposed to the virus. In any case, there's nothing you can or need to do about it now. I wouldn't be too concerned. The incubation period is 5-10 days or so, by the way, so if it hasn't happened by then, you're in the clear.
Best.

Thanks Dr. Rockoff - I guess I was under the assumption that you are contagious when you have the blisters and not before they appear, and then I read about this asymptomatic shedding which kind of scared me (after all it was just one quick kiss). It has been 5 days since I kissed her and no cold sore.
