Because this movie was so awful, I entertained myself by watching for bechdel test signifiers. The two named female characters are not in the same scene until at least an hour into the film and the closest they come to a conversation is where they each have a line of dialogue, one after the other, that may or may not be related (in context one or both of them may have been talking to themselves). This is at one hour and 14 minutes.
It's a strange zombie apocalypse where the ratio of survivors is greater than 7 to 1 male/female.
Probably this goes without saying, but the film passes the reverse Bechdel in its first five minutes.
