She adopted a baby, named Shogo Lee, because you know, a floating timeline actually moves on and Jubilee was a young adult.
As for her trying to bite characters, she was tempted, but no, she didn't. Being one of Wolverine's sidekicks and proteges gave her an insight in the savage beast inside. And yes, every character in the X-men knew she was a vampire, they couldn't really hide it when she had fangs and red eyes.
But really, other than a few storylines, I think Vampire!Jubilee just faded into the background between 2011 and 2018, she didn't have the prominence of other characters.
