If someone kissed someone with possible exposure to rabies (bat bite) before the full course of the pep was finished could they contract rabies?

Rabies transmission: Per the Centers for Disease Control: The most common mode of rabies virus transmission is through the bite and virus-containing saliva of an infected host. Transmission has been rarely documented via other routes such as contamination of mucous membranes (i.e., eyes, nose, mouth), aerosol transmission, and corneal transplants.
